Why does the refrigerator work loudly and what to do in this case?

Main reasons

The reasons that the refrigerator is working loudly quite a lot. A common problem is the contact of the water pan with the compressor. As a result, the vibration is transmitted to the plastic and because of this, increased noise is created.

This problem is solved quickly and easily, you need to feel the pallet with your hand and pull it a little towards you and the noise should disappear. If this does not happen, you need to look for other reasons why the refrigerator began to make noise:

• The equipment stands on an uneven surface and, as a result of tilting, the compressor comes into contact with other components, for example, tubes. How to eliminate noise? It is enough to adjust the legs, set them so that the unit is aligned and the compressor moves away from the surface in contact with it. This is done very simply on their own. Read more about proper installation of the refrigerator we told in the corresponding article.
• The shock absorbers were loosened and as a result, the device rattled and made a loud noise. Here it is necessary to gradually tighten the fasteners and seize the moment when the crack disappears.
• The compressor model, due to design features, makes noise, knocks or clicks loudly during operation. The reason is often a high refrigerant pressure. Only a specialist will help here.
• Shipping bolts have not been removed. This point should be paid attention immediately after the refrigerator is installed. Otherwise, it will work very loudly.
• A model equipped with two compressors, in any case, will work loudly, since the standard noise level is doubled.
• Compressor running out, wear or breakdown. In this case, it is necessary to contact the master, self-repair without experience, skill and a specialized tool will cause the old refrigerator to completely stop working.

Some of the listed malfunctions can be completely repaired by yourself. Below in the video we looked at how to fix the breakdown if the refrigerator hummed like a transformer or started knocking.

Other malfunctions

If the refrigerator works and does not turn off for a long time, then this is an alarming sign. The reasons for this:

1. Deterioration of the rubber seal, as a result of which the compressor cannot reach the required temperature and works continuously. If you do not take action, then soon it will fail. It is better to entrust the replacement of the seal to the master.
2. Refrigerant leak. Another sign of this malfunction is that the refrigerator is working and does not freeze. This problem should also be fixed by a specialist.
3. The device is located in a room where the air temperature is high, as a result of which it cannot reach the desired temperature and works for a long time without turning off. But here it should be borne in mind that after a certain period of time the compressor should turn off. But in this case, you must call the wizard.
4. Damage to the temperature control circuit or circuit board.
5. The thermostat does not work.
6. The relay is broken.

The last three reasons are most common to the question: "What to do in such cases?" there is only one answer - to call a qualified specialist. Actually, all of the above reasons are eliminated by the master, as they relate to the technical device of the refrigerator. What threatens to ignore the fact that the device works without interruption and at the same time makes noise, it’s not hard to guess - this is a serious breakdown and expensive repair, and it is quite possible to purchase a new device.

Psychological factor

In the modern technogenic world, the human body experiences stresses from excessive noise and information load. The logical result is the desire for absolute silence, which the slightest noise can disturb at home: the clock, the neighbors' loud phone ringing and the loud operation of the refrigerator itself. In this case, only rest will help. Also, you should not listen very much to how loud the old refrigerator is working.

Attention! There is no absolutely silent model. Any compressor installation at least a little, but noise and vibrates. These features are eliminated by technical means: shock absorbing devices and optimization of refrigerant pressure. Therefore, to expect from the refrigerator a complete absence of noise, even if it is new, is useless.

Common Misconceptions and Useless Tips

There are several tips and opinions of pseudo-professionals that you should not listen to. The most common myth is that if the new refrigerator is working loudly, makes a crack, makes noise, you need to let it work for a while, and these side effects will disappear. By the principle of a car that is being tested.

The only difference is that the refrigerator is much simpler than the machine and there are practically no moving parts that need to be rubbed in. This mythological theory was invented at service centers in order not to take deliberately defective equipment for repair or to bring it to the point of no return after 14 days after its purchase.

Attention! A working, new refrigerator initially works, making a moderate noise.

Another myth says that if the compressor is noisy, then it definitely needs to be charged with refrigerant. First, you should diagnose, and then take any action. The causes of the problem can be different, so you must first identify them, and then eliminate them. Do not immediately begin repairs.

It should be noted that the process of measuring the amount of freon and its refueling is carried out using specialized equipment. It’s cheaper and easier to pay a master than buying it and learning how to use it.

It should be remembered that in case of technical malfunctions it is better to contact a master whose qualifications are beyond doubt. We hope we helped you figure out why the refrigerator is noisy and what to do in this case!
