The microwave does not heat food - a list of possible reasons
Simple faults
There are cases when a failure is caused not by a breakdown of the "inside" of the microwave, but for reasons such as:
- Low voltage - less than 220 V. Even a small deviation (at 20 V) can affect the performance of the microwave oven, including the possibility of heating. As a result, the plate may be heated, and the food in the center will be cold. To solve this issue, it is recommended to install an uninterruptible power supply unit.
- Going on network congestion as a result of the operation of two or more powerful electrical appliances from one outlet. In this case, it is necessary for each consumer to bring a separate outlet.
- The door broke, or rather its latches. As a result of incomplete closing, the microwave slightly warms the products. The solution is to repair or completely replace the latches.
- Maybe the wrong mode is selected. For example, if before that you set the oven to defrost, then you forgot to switch back. The defrost function will not be able to heat food to a high temperature, as a result of which you will think about how to repair equipment that is already working.
If not one of the listed options is suitable, the most likely reason that the microwave does not heat food is the failure of the fuses, capacitor, magnetron or high-voltage diode. Next, we will consider options for solving each of the problems.
Breakdowns are more complicated
So, we will consider how to correctly identify a malfunction and, accordingly, repair a microwave oven with your own hands.
Before proceeding to independent troubleshooting, be sure to unplug the microwave from the network and find instructions for it. The instruction is needed in order to know where all the elements of the circuit are located, which you will check.
Fuse
The first thing you should do when removing the cover is to check the fuses are working. If they turn black or the filament inside is blown, then you just need to replace the fuse with a new one. Typically, two fuses are installed inside.
We draw your attention to the fact that when buying a new fuse, it is best to take the old one with you (which burned out) from the house to buy the exact same type of product. We strongly recommend not using so-called “bugs” made of thin wire, which can save the situation. In this case, the probability of a fire is extremely high, in addition, the cost of a normal fuse does not exceed 50!
Video instruction for finding the possible cause of the malfunction:
Installed and did not help? Consider what else you can do if the microwave does not heat food.
Capacitor
If you hear a buzzing sound or abnormal noise from the inside when you turn on the equipment, the capacitor may be broken. Its performance is not at all difficult to verify. To do this, you need an ohmmeter that connects to the part itself.
If the arrow of the ohmmeter deviates, the capacitor is in order, if not, it is out of order, so the microwave oven makes noise during operation.It should be noted that before checking (in fact, as well as replacing), the capacitor must be completely discharged!
If suddenly, during the operation of the equipment, you notice that something is cracking inside the camera and at the same time you can hear the stink of the burner, we recommend that you look at what broke in this case:
High voltage diode
Usually testing a high voltage diode is not carried out, citing the complexity of the work. Indeed, it is much easier to buy a new product, the main thing is to make sure that the problem is in it.
To determine the malfunction of the diode, you can use a high-voltage capacitor (it should not heat up). Two more obvious signs are the fuse blowing and the buzzing of the microwave oven when it is turned on (if the equipment is humming harder than usual).
Magnetron
If you checked all the elements of the circuit and there were no malfunctions, most likely the reason that the microwave does not heat is in the magnetron. Its purpose is the generation of a high-frequency electric field, which carries out the heating of products in the chamber.
A characteristic sign indicating a malfunction of the magnetron is an increased hum during the operation of the equipment. If the microwave is buzzing but not warming, you must visually inspect the part for carbon deposits and cracks. If there are no defects in appearance, check with an ohmmeter (the housing should not ring out with a feedthrough capacitor). A burnt magnetron must be replaced with a new one, with exactly the same dimensions and specifications!
Reasons for Failure
So, we told you what to do if the microwave does not heat food. However, it is much more important to answer the question: “Why did the microwave oven stop heating?”. The answer is quite simple - most likely, you misused the equipment.
The main reasons why the microwave does not warm food are:
- heating food in metal utensils (objects also belong here, for example, a spoon);
- inclusion of equipment in idle mode (without products inside);
- wear of spare parts over time;
- warming raw eggs and liquids in closed containers that explode when heated.
It should also be noted that cheap Chinese equipment breaks down due to poor-quality assembly, so if you buy a questionably cheap device, remember that “the avaricious pays twice”. Finally, we draw your attention to the fact that if the microwave oven is under warranty, in no case do not open the casing and do not do it yourself. Better immediately go to the service center, where experienced specialists will test and repair the device at the expense of the company.
Finally, we recommend that you look at another useful repair manual:
We advise you to read:

Hello, my microwave does not work when I turn it on to warm food, it doesn’t get warm, and the lamp is infrared. It smokes! TELL THE PROBLEM
Can you specify the company and model of the microwave? In general, there are many reasons why a microwave oven is smoking. Most often, the problem is the failure of the transformer or magnetron. They need to be checked according to the methodology provided in the article.
Good afternoon. I have this situation: in the microwave, I thawed the meat, put it on defrosting, after which I put it to warm ordinary food in medium mode, the stove started from the inside. Heats food, but smokes. Smoke comes out through the upper air compartment. What is the reason? I washed bread crumbs from fat, etc.
Hello! Have you looked at the condition of the mica plate? Perhaps the reason is in it and it will just have to be replaced. Watch the video provided above in the article, there a completely similar problem is considered there!
Wash Ten
Good afternoon! The microwave does not spin or buzz, the light does not light either, but at the same time the menus and buttons work as they should, time goes by.
During start-up, they click (reels?) And the countdown goes on, but complete silence at the same time.
What could be?
As already written in the article, take a multimeter and alternately ring all the elements of the circuit. Perhaps the magnetron or the capacitor is out of order.
Hello! I have a Samsung microwave - -SE- is lit in the viewing window and not a single button responds to anything. What could be the reason? thank
Good afternoon! The Samsung SE “SE” error means that the touch panel button is locked. Most often this happens due to dust or moisture entering the sensor. Try to carefully disassemble the microwave and clean the touch panel with cotton dipped in alcohol. If after that the error does not disappear from the display, most likely you will have to replace the sensor with a new one.
Doesn't work at all Can the lamp be the cause?
Hello! Where does the lamp not work in the camera itself? And what about everything else - does the plate spin, does the display work, etc.?
Hello, I have a whirlpool microwave oven, I turn on the microwave, and after 40 seconds the fuse blows, I turn on the grill without a microwave everything works. What could be the reason? thank
Good afternoon! Please tell me which fuse is blown? There can be up to 3 pieces, with different parameters of the current strength (1.5-2 A or 8-12).
H520 10A 250V 5 * 20 glass, no more fuses.
So, most likely, the magnetron failed. Try ringing it with a multimeter!
The Elenberg microwave oven, worked for about 10 years, stopped heating, there are no burnt parts, like a new one, the circuit has not yet been tested. Many services with this company do not work. Does the basic elements of a microwave have a certain service life? How long will a repair last for a long time?
Good afternoon! Well, the warranty period has already passed, and a 10-year service life is not a very high indicator. Check the circuit with a multimeter and replace the defective element, maybe it's just a fuse. Repair will extend the life of the microwave oven indefinitely if used properly.
My Sanyo microwave is working but does not heat, visually checked the high-frequency fuse seems to be suitable
Good afternoon! It is necessary not only to visually look, but also to check the circuit with a tester. In addition, follow the rest of the recommendations that are outlined in the article!
The magnetron stinks, the fuse (high voltage) was burned out, replaced it. Magnetron kapets?
Hello! After replacing the fuse, the microwave began to work normally? Have you tried the tester to ring the magnetron?
In fact of the matter! The magnetron stinks, and it seems. For a long time I do not turn it on, suddenly a fire ?? I didn’t call a tester - I don’t know how. Magnets scroll - should it be? In appearance, the magnetron is ok - it’s not melted anywhere, everything is whole, as in your photo.
Here's how to do the verification - https://www.youtube.com/watch?v=0IEDsGtkJPE And what kind of magnets are scrolling?
the microwave oven is turning on, the light is on, the fan is working, everything is working as if the microwave was working, but it is not heating, voltage is 220, the network is not overloaded, they did not turn on the empty one, Daewoo company,
Hello! So, call with a multimeter all the elements of the circuit. In the video tutorials, the article examined in detail the verification technology.
Turn on the LG microwave, the light turns on, turns on, the timer is set on the timer, but the countdown does not go and the food does not heat up at all. He took off the lid, visually damaged on the insides, and there were no traces of soot. How to be?
Apparently a malfunction in the electronics. Here you are unlikely to be able to solve the problem yourself and have to call the wizard. The only thing that I will advise, if the food does not heat up, check the fuses and magnetron!
My Elenberg microwave broke the microwave switch, it melted inside, tell me where to get the new switch
Avito to help :) In addition, you can travel to service centers, they often buy up broken equipment for parts. Perhaps this is how you can find the right spare part.
Samsung microwave burned out a high-voltage fuse in a plastic case replaced but without changes. The stove is buzzing and that's it. According to your stories, I understand that this looks like a high-voltage diode. Tell me?
The stove buzzes and warms up
Good evening! Most likely yes, try replacing!
Good day. I have a LIBERTON microwave oven, I tried to heat water in a glass but nothing happened, it turns, it shines, but it doesn’t warm. What can it be?
At the very first video in the article, your problem was just considered. The master is repairing a Daewoo microwave that has a fuse blown.
Dismantled the microwave, did not work. The light is on when the door is closed, I close the mikrik, the fan starts to work and nothing else seems to be working. Does not respond to start. MB fuse? He is there alone, so no, the display is on
There may be three fuses ... read the comments above, I described where it is installed. Check all circuit elements with a tester.
Hello, I checked the entire fuse chain, everything is normal, but the microwave does not heat and does not take the load from the network (I look at the voltage regulator in which it is connected). The light is on and the plate is spinning. Sometimes extraneous noises are heard, I checked the capacitor as shown in the video, it does not break. What is the matter?
Good day, Sergey! Check magnetron and high voltage diode. Usually, if these two elements of the circuit fail, you can hear extraneous noise. If you are convinced that the magnetron and the diode are intact, it is better to take the microwave for repair for expert diagnosis.
Good afternoon! The bolt inside, which held the grill, began to sparkle. Why?
Hello! Most likely, the microwave sparks due to severe contamination. If the bolt is grease, thoroughly clean it. The second reason may be a breakdown. In this case, you need to visually view all the connections for an open.
tell me, watched your video about the fuse, looked it burned out, made the thin wires and turned on the wires, it doesn’t burn out and the smoke starts to go from the motor, what devices to do
Hello, Eugene! In the article, we separately highlighted the phrase that we strongly do not recommend using wire bugs instead of fuses. We have attached the video in order to show where the fuse is installed in the microwave and how it looks. If there are no appliances, it will not be possible to repair the microwave oven yourself.
Hello, we have a Samsung m1712nr, the stove began to stink of plastic and did not heat the food. No one can hear the noise, the fuse in the plastic is whole, the other 2 are white. I didn’t notice any visible damage ... Tell me, what could be?
Good afternoon! Alternatively, the mica plate causes a breakdown. The article provides a video showing how to replace this spare part with your own hands!
Hello! The microwave only works in the morning and in the afternoon, and in the evening it works, but it doesn’t warm. What is the reason? Mb voltage drop? But before that it was all normal)
Hello! The situation is certainly interesting, it is possible that this is due to power surges! Does the light in the chandelier flash in the evening?
No, they are not blinking — voltage is 216 volts — just measured by a tester.
two years ago it was repaired, it worked fine for a year and then it became) day)
The situation is really very strange. You can try to put a voltage regulator. More than sure that the reason is still precisely in the tension. Morning and evening time in no way affect the operation of the magnetron and other elements of the circuit. If the voltage stabilizer does not save the situation, then it is better to take the microwave for repair, so that the masters make a more accurate diagnosis.
P.S.
It’s better to find other repairmen, and not those who did it last time :)
Hello! I have a Samsung microswitch. To make noise, the light is on in the window. but you turn it on to heat food, it doesn’t warm, and the plate does not spin. What is the reason?
Hello! In the article we described everything in detail. Have you tried to find the reason for our advice?
Good afternoon! If you can, tell me please, where are the fuses in the Whirpool AMW 480 microwave. I’ve already examined everything, but there’s nothing like in the video. Problem - the plate is spinning, the lamp is on, nothing is warming ... at the start a click is heard.
Hello! Unfortunately, I have not found a photo of your model disassembled microwave oven anywhere, so it will not work to show the location of the fuses. Look at the scheme, if it is in the passport.
Hello. Can a magnetron die suddenly? The heating abruptly disappeared, then it appeared and disappeared completely. All fuses are intact. I installed a capacitor and a diode that were known to be working, I checked the contacts, the lock switches, too, the magnetron itself looks normal, there is nothing short anywhere. Even the relay in the control unit checked. Moreover, the magnetron heats up, as if working. Samsung stove.
Good afternoon! Did you call him a tester? The situation is of course difficult, without a visual inspection it is difficult to answer, but if all the other elements of the circuit are working, then the magnetron probably broke. Although electronics may fail in this case.
Electronics live, I even pulled out the power relay and separately checked. And at work you can hear how it works. I don’t even know directly, it’s just amazing what happened so dramatically.
What clicks does not yet say that it is functioning. It is necessary to check how the contacts work, i.e. tester-norms closed and open, when turned on should work.
Magnetron, naturally, rang - as lively and looking good.
Well then, unfortunately, there are no more ideas. You just need to watch everything live!
Hello. Samsung microwave oven, after moving it began to work strangely, the light turns on, and the plate does not turn, you start to move the microwave, the plate starts to turn and warm food. What could be the problem? Thanks.
Hello! Maybe where the contact goes? Disassemble, check all connections. Most likely, when moving, the microwave oven either fell, or simply due to vibration, contact was broken.
Hello, I have such a problem of warming up food. After about half a minute, there were two loud pops like explosions and after that it works, but it doesn’t heat anything.
Hello! If the microwave oven does not heat food after the cotton, but the grill works, then with high probability we can say that the reason is the failure of the magnetron. Disassemble the microwave oven and visually inspect the magnetron. If it has soot and cracks, you can look for a suitable replacement.
I don’t know about the magnetron, I looked, a fuse with a speral was out of order and I don’t know where to get one in our village (((
the mechanical timer stopped turning off the microwave. LG
Hello! If the microwave does not turn off automatically, you need to disassemble the mechanical timer and inspect it. Most often, plastic gears are destroyed or the contact opening mechanism is damaged. Only a visual inspection will show what is the reason!
Hello! The LG MH-6342 BS microwave oven was turned on at high humidity, above the grill, soot appeared on the grill. And now, when turned on, there was a hum and a burning smell. What could be the reason?
Good day! If the microwave is noisy and a burning smell is heard, first check the mica plate. After that, a high-voltage diode, capacitor and magnetron. All in turn, as described in the article. Unfortunately, I did not find an example of this disassembled microwave oven to see what is on top of the grill. Disassemble the case and make a visual inspection, this will help to find the breakdown.
Thank! The plate is in order, visually the whole is on the body above the grill where the ventilation is direct these holes are burnt. Burnt and the grill body is safe and sound!
Hello! I have such a problem. Mikrovalkovka lg stopped warming, for about 10 years she decided to change the change apparatus. I bought Samsung 02/14/2016. One day I worked and all the same ceased to warm. The tension in the apartment is the norm! What could be the problem? Thanks in advance!
Hello! If both the old and the new microwave do not heat, the matter is definitely on the network. Try to check at night, so at 12, when there are no problems with power surges. Another reason is incorrectly selected dishes for warming up.
The dishes are used correctly and I’ll try today about 12! Thanks tomorrow I will unsubscribe. If the problem is in the network, then how to deal with it?
Here is the whole article in which we all described https://our.electricianexp.com/en/kak-borotsya-s-nizkim-napryazheniem-v-seti.html
As promised, unsubscribe. tried to turn on at 12, silence! I drove to the service replaced magnetron and candera. It all worked! Thank you very much for being so responsive !!!
Hello. Microwave lg when plugged in, no signs of work. Fuses are intact.It doesn’t ring on the board, I don’t know what it’s called, such a black rectangular plastic garbage with two terminals to which power is supplied on one side, and on the other it is soldered to the board, on it there are inscriptions 16a 277v, smh-112dm, can it does the microwave work and should it be called by the tester?
Hello! This thing is called a start relay. I recommend you take the microwave to a service center, as this kind of fault should be repaired by the master.
300 km to the service center, far to carry. Duck should this relay ring or not. I like a beginner electrician is interesting.
It is checked by connecting a 220 volt light bulb and a power supply. If the lamp is on, the relay is operational. You can even check by dialing, look at YouTube, there are several videos there, write “relay check”,
Good afternoon. Yesterday, 02.22.2016, the chicken was fried in the microwave whirlpool chef there was a strange noise from below under a spinning plate. The noise was like a crack. Tell me, please, what could be the problem?
Hello! The reason may be a failure of the plate rotation motor. In addition, as already indicated in the article, a microwave can crack when a magnetron, a high-voltage diode, or a capacitor breaks. All these circuit elements must be checked visually and by a tester.
The whirlpool microwave is not only noisy; even when the door is closed, the “growls” sound resembles a spinning top.
Good afternoon, tell me please, I boiled eggs in the microwave, they exploded, the microwave does not work at all, what could break in it? Thank you in advance!
The first step is to check the fuses. Most often, the fuse blows when the eggs explode in the microwave. If the fuses are intact, check the mica plate and magnetron.
Hello. I have a Scarlet microwave. It worked for about 8 years without problems, but recently, when the door was opened, the machine began to knock out and after turning on the machine it does not work, that is, nothing burns and does not move at all. I gave it for repair, the master looked, changed the magnetron and it worked. Arriving home, he plugged it into a power outlet, opened the door and again knocked out the machine and the stove stopped working. Tell me what can be and how to deal with it? Thanks in advance!
Hello! Most likely the matter is about microswitches of blocking, it is necessary to replace them, although fuses usually burn out, and not a magnetron. The magnetron itself most often burns out during power surges.
Good afternoon! I have a LG microwave, when I opened the door while the oven was working, an automatic machine suddenly flew out in the kitchen, i.e. for proper operation it was necessary to wait until the mode was completed or press the cancel button. And on one unlucky day, after the same pressing, before the end of the mode, my microwave broke. Tell me, does it make sense for an easy repair (maybe a fuse) or buy a new one?
fuses magnetron and viscera are clean, there is nothing that has not melted or burned down
In the repair of course there is a sense. If all the fuses are really clean, check the interlock microswitches. Most likely the reason is in them.
You have a mistake in the photo where the arrangement of the parts is signed ... There is no diode, there is a high-voltage fuse ...
Thank! That's right, error, the diode is slightly lower and to the right of the capacitor.
Hello, help me. I have a microwave LG. He doesn’t have a sensor. How can I check it? Thank you in advance
If you have experience, you can check by visual inspection and a tester.
Can he fix the torn contacts of the sensor?
The master thinks he can, often they make new tracks and restore old ones, and if you need to solder the contacts, this can be done accurately. The only thing - it all depends on the complexity of the damage. In general, you only need to look in fact. If you do not have experience with a soldering iron and microcircuits, it is better to take the microwave oven to the workshop.
Good afternoon. Tell me what to do. The old Elenberg Ms1700M microwave oven stopped heating food. When working besides the noise of the motors, periodic clicks are heard inside the microwave oven with an interval of 40-50 seconds, as if the relay is triggering. It is not visible inside the visible damage, the high-voltage fuse is intact, without a break. what could be the reason? Thanks in advance.
The reason may also be in the high voltage capacitor or diodes. You need to remove the cover and determine exactly where the click comes from. Rarely, it happens that a microwave clicks when a magnetron is faulty.
microwave LG with a grill, the food heats up normally, but there is a crackle and a burning smell, the whole mica, removing the case, found carbonization of the wire and the plastic fence at the point where the wire was connected to the heater. I do not use ten at all, what is the problem?
Hello! The microwave does not heat up, when you turn on the smell of burning (plastic). The master checked everything else, the worker said. Can a transformer fail? thank
And one more question. Are the R1S58A and R1S58B transformers interchangeable? Deo KOR634RA oven. thank
the problem is that the microwave does not warm, sinned on a magnetron, but here all the rules. it turned out that the fuse was blown, put a bug out of soft wire, one hair. he turned on the microwave, it worked for 4 minutes, smoke came from the secondary winding, began to sin on the capacitor, but it was as if without signs that he was dead. I checked the diode, the diode is not working, because when the current rings, there are 2 directions.
I want to change the diode, and the capacitor! do i think right ???
and have I burned the secondary winding ???
Hello
LG oven. When the door is opened, the light turns on, the saucer begins to rotate. I close the door and turn it on - the light does not light up, the saucer does not turn, and the food heats.
Opened checked all the fuses with a tester, all intact. I removed the cantacts from the door sensor, turn on the light, turn on and turn the saucer but do not warm.
I'm sorry Samsung oven
Great article! Thank you so much! We bought a fuse for 100, saved 6 thousand))
Good evening! Microwave Vitek VT-1681W. As usual, I decided to warm up the food, but when I turned it on after a second, there was a pop and the microwave began to buzz loudly and stopped warming the food. The display works, the light inside is on, the plate is spinning, but the food does not heat up.
Thanks in advance!
Hello! The article describes all the possible reasons. Have you tried the test, as we advise?
CHANGE DIODE AND CAPACITOR
I have a samsung microwave pg113ur for many years stood idle due to a breakdown of the grill mode switch, I thought of trying to repair it, it turned out that there are no such switches anywhere in the market. I found one local kulibin who restored the switch, it didn’t work out very well because half of the modes didn’t turn on, but half worked. I decided to try how the microwave itself would work, but it turned out that the masonry pad I had worn out many years ago was therefore discarded. I decided to try it to replace it with anything, in general, they closed the waveguide with a piece of semi-transparent plastic, put a 300 ml cup of water from the tap, 1.5 minutes were hammered in. The water in the cup was heated, but not very much. After that, the wife wanted to cook to eat zucchini in it, she has an Helenberg oven at work for 15 minutes, one of them is a wonderful dish. and here disappointment occurs, they chased her for half an hour, the stove warmed up inside and outside, but the products remained absolutely raw only slightly warmed up. therefore, the question is whether such nonsense can occur due to the lack of a mica plate, or is it necessary to look for a reason somewhere in the bowels of this monster?
Good day.
I’ll write about my problem because I searched the Internet for a long time and could not find anything.
Microwave Rainford (one in one with LG). Pretty old. Already there, the engine changed, and the high-voltage fuse, and the bulb.
But recently I encountered such a problem: the pallet does not spin and the lamp does not light. At the same time, the microwave itself warms up.
I reviewed a bunch of websites and a mountain of videos on repairing microwave ovens, but I couldn’t find an answer anywhere.
I decided to go through the nodes. The lamp is working. Pallet motor too (R ~ 10 Ohm).
I removed the control board (it is rather inconveniently removed), but I did not find any visible defects in the form of burnt parts. Once again went through the chains of the lamp and engine. Checked the microswitches. On average, there was a short circuit in the circuit (R = 0 Ohm), but the mikruha itself, when I got it out of the circuit, turned out to be quite working.
He climbed onto the Internet again, and again found nothing.
Then, having decided that he would nevertheless have to carry the microwave to the service, he decided once again, lastly, to walk along the chains of the light bulb and the engine.
The chains go to the engine and to the light from the control board (yellow wire), and no current flows from the beginning of the chain (from the control board) to the end parts of the chains (the multimeter showed 0 Volts of alternating current instead of 220 Volts).
He took off the control board again (since it remains only to sin), and finally saw that there was no part of the track on the control board (?!?!?!), Which is just going to the yellow wires (the beginning of the chains to the lamp and engine).
You see, for some reason (there may be a marriage on the printed circuit board itself - there is some kind of microcrack, or the board was not corrupted normally, but a speck of dust got in and caused a short circuit in this section, because it was the weakest), the track on the board was simply burnt out.
I soldered the contacts of the burned-out track with an insulated wire, and it all worked.
Good afternoon. LG microwave When you turn on, you hear a loud hum and after 3-5 seconds. The mains fuse 10A 250v burns out. The magnetron seems to be intact, the feed-through capacitors on the case do not show anything, the filament is a resistance of 0.9-1.0 ohms. Before this there was a burnout of mica and sparking on the body. He replaced the mica, cleaned the burnout place and covered it with heat-resistant paint, replaced the protective cap on the magnetron (it was scorched but not burnt) did not help. Please give repair advice.
Thank.
Tell me please! Four days ago, they bought a Samsung microwave, it worked just last night, today they didn’t turn it on all day. I wanted to warm up the soup, but it does not make noise, the dish does not spin, only the light comes on
Hello! Please help, I will soon bite the stove, examined everything and measured it and ??? Samsung C105AFR. During the warm-up, something “cycled” and a rumble appeared, and the warm-up stopped. The network is normal, the control unit is normal, U is trans. arrives, R primary 3.2 OM. secondary 174OM, R diode 17MOM. to another 0, checked through a light bulb 40WT-floor heating, normal. Capacitor, there is no leakage to the body, the charge on the device with + on is normal, tested so through a light bulb, a very weak glow. Magnetron-R incandescent 1.35OM. There are no leakages on the 200MOM. Replaced mica in the chamber, there was a burn. When turned on, it buzzes, the trance heats up. and magnetron. I changed the magnetron from my native OM75P (31) to the second one. OM75S (31) - there is no drone, but it doesn’t work either. Well, in my opinion that's all, and maybe not at all. Your opinion? Thank you very much in advance!
Sorry, forgot, there was a blown 800MA fuse.
Good night. A microwave with a grill function and Samsung convection simply did not turn on on one “fine day.” The fuse in the shield was knocked out. As a result, with each attempt to turn on the microwave, the fuse in the entrance was knocked out, and the metal tips of the plug melted. What could be the reason, all 1.5 years of operation. We only warm in special dishes!
Hello. Microwave Samsung CE2813NR.
Problem: when you turn on the microwave inside the light turns on and nothing else happens. Neither buzzes nor buzzes, the pan does not spin and the stove does not heat. There are no extraneous odors. Everything is clean inside.What could be the reason?
Thank.
Hello. Microwave Sharp R-7A58 (1997 year).
The button for opening the door began to jam - I took it apart - one of the button locks broke, the splinter blocked a full press. Eliminated. At the same time, I decided to clean it (including using numerical means). Well cleaned - but to see in vain.
I suspect that a few drops could get somewhere on the wires or boards.
After assembly, a defect appeared - the microwave or oven starts up as usual, but after 2-3-4 minutes the backlight goes out, the turntable stops, and the heating stops. At the same time, the control panel continues to count the time and the magnetron fan is buzzing.
If you turn it off - turn it on - there is no heating.
If you turn off and on after a few hours, the microwave or oven works normally for 2-4 minutes.
I checked several times - after a long shutdown (until morning) - a short work, another moment - if you turn it on several times for a short time (for example, warming up breakfast, pastries, etc.), the total working time is longer, but if it "goes out" - all by a few hours.
I did not find any visual damage or traces of the strait.
There is no principle circuit.
Advise - what can give such an effect.
Hello! Yes, the problem is certainly not typical. It is very similar to a circuit, maybe on what board the cleaning agent got, that’s short of it during operation. Without a scheme, it is very difficult to say for sure. Try using alcohol to wipe all electronic components near the cleaning site. After that, let them dry out a little, well, then already test. It doesn’t help, it’s better to call the master until the microwave burns out at all.
Hello! Scarlett’s microwave, it stopped warming, everything else is on and on. It worked for 10 years without problems, once it failed, it stopped by itself and turned off. Turned it on, continued to work. What could be a prick?
Hello everyone!
On occasion, the Elenberg MG-2545D microwave oven did not work (does not warm).
After opening, I discovered the complete absence of a high-voltage diode (maybe someone used to open it and unscrew it before).
Tell me, who knows, the marking of the diode.
Hello, tell me please, after replacing the mica and the cap on the magnetron (the previous one was burned out), the microwave periodically makes clicks when it is turned on, almost every minute, the microwave heats up, everything turns, but these clicks lead to a dead end, they seemed to be before (before repair) but it seems not so loud. (Microwave DAEWOO). Thanks in advance.
Hello! You need to disassemble and see where the clicks come from. It’s difficult to guess here, especially if you replaced the mica and cap.
Dismantled, looked, closes nothing, and clicks go somewhere from the side of the timer. Maybe this is her norm?
In that case, perhaps yes.
and also tell me please, I have one more microwave oven -Grill Samsung, she has a fuse after work, when the door is opened, the fuse blows, everything works ideally. I read that they write that the whole thing is in the castle, it’s kind of sticking somewhere, sorted it out, looked - I don’t see anything, all of them probably need to be replaced? Thank.
Yes, it is better to replace all microswitches of blocking. Some craftsmen manage to open each and watch contacts. Where burnt - and they change.
Thank you very much, you helped me a lot)))
And if what to do when working inside the zipper, thanks
Tell me, LG MH6342BB. There is some kind of easy start click inside as usual, but it doesn’t spin the plate, it doesn’t warm. There is a backlight, the timer goes on, the buttons react.
I figured it out myself. In my case, apparently there were poor 220V transformer contacts.I disconnected them, hung a multimeter on them, turned on the microwave, saw that there was 220V, put them on again, turned them on again - and it worked.
Good afternoon, tell me please, the built-in microwave oven gorenje bm6250oraw has stopped heating food, and the grill is working, everything is spinning and glowing, there is no smell. But for some reason, when choosing the microwave mode, vibration starts, it used to work quieter.

Hello!
Microwave Panasonic NN-V320M. I have such a problem. The microwave does not turn on, the light does not turn on, the display does not work, the buttons do not respond, it is completely dead, but the plate is spinning. It starts spinning from the moment I insert the plug into the socket and spinning regardless of whether the door is open or closed. Do not tell me what could be the problem?
Good evening. Can you tell me the cause of the malfunction? The microwave is working. But ... when you put it on 360 and 600 it works very strangely, it drones very loud, then it can quietly on the contrary ... the sound changes a lot. But at maximum, there is one sound ... What then the differences ...
I can’t identify the reason for heating 2 resistors near the relay. repent until red. help identify and eliminate the cause. the microwave itself warms up, but does not manage to heat enough due to these resistors. have to turn off every 10 seconds.
the problem is resolved. replaced the relay and 2 of these resistors.
Good afternoon! The Daewoo microwave has been operating since 2001. Recently, there have been problems with heating food, the dishes are hot, and the food is cold. And the microwave goes off several times during the set time period. Please tell me what is the reason and whether it makes sense to repair it. It may be easier to buy a new one, although you cannot trust a new one now because of poor quality.
Panasonic microwave exposure mode, turn on for a few seconds, then displays error H 97. Please tell me what it is.
Hello! Thanks to your advice, I repaired the CANDY microwave itself. Everything also worked, but it didn’t warm ..., it turned out the whole thing in the fuse, which goes from the capacitor to the tansformer, burned out. I put a bug to check and began to warm, I’ll go now to look for such a fuse. But, here’s how to check the capacitor, I somehow didn’t understand, I inserted the dial into the contacts - it doesn’t ring, doesn’t break into the case either, is everything okay? ... Oh, but I already bought a new microwave with a fool, I wouldn’t have to climb on the Internet first) )) There will now be two)).Thank you for your good advice, but please write about the capacitor ...
Hello! Glad to help! We have a separate article about capacitor testing https://our.electricianexp.com/en/kak-pravilno-proverit-rabotaet-li-kondensator.html Check out if something is not clear, ask questions.
Microwave Panasonic. NN-C785JF. The lamp does not light, the plate does not spin, the food heats up. Tell me what to watch. The engine and lamp rang, workers.
Good afternoon, LG microwave
To begin with, I sparked, disassembled, unscrewed the steel cap from Megatron, it stopped, now everything is working now, but not for 15 seconds, then it’s disconnected itself, what’s the problem, tell me
if it just sparks, then most likely it is a protective plate, as a rule it is to the right of the door, it is easily removed, if there is a burn on the back side, then it’s the matter
The food does not heat up, but the plate is hot oh.
Try less salt. A friend came to me to cook soup, and the microwave does not heat it, he warms the plate. I disassembled it blew, shook out cockroaches. Everything is also a plate of hell, ice soup. Shoveled tyrnet 0. And glory to Kulibin, the nature of torture realized that just water without NaCl is heated to normal.
Hello, the microwave began to warm slightly, then after a while, and then completely stopped. I looked at the fuses and looked normal, the power to the primary winding is normal, it also goes to the magnetron, I did not have time to see anything else because I was in a hurry. Do not you say I think correctly that a malfunction is in the magnetron? 2013 LG Microwave.
Hello, help pzhl, the microwave works as before, but does not heat the food. The buttons work, the light turns on, there are no noises and no sounds, there are no smells, the door closes well. Food does not heat, but it can warm up several times when turned on and off, but there’s not always time to do this. Tell me what could be the reason.

The stove got very hot, I turned it off, it works - but it doesn’t heat, I have a Swiss company TRISA. Maybe right in the morning to call the master?
Here you have a Swiss company) That is, by "running" you mean that it turns on, the timer is ticking, but it does not heat? Of course, call the wizard, there may be a problem with the magnetron or with the control circuits.
