Everyone knows what sounds the refrigerator makes during its operation. But it happens that new sounds are added to the already familiar, and therefore invisible, sounds - the refrigerator beeps, clicks, makes noise, buzzes. Naturally, many home appliance owners are concerned about this state of things. What can it be, how scary such sounds are, and what to do? Let's get it right.
What should be the noise level of the refrigerator
According to GOST 163-17-87, the noise level of a running compressor should be no more than 53 decibels. But this is the ultimate value, and in modern models it is almost never found. There are very quiet refrigerators with a noise of 20 dB. But most often on the market are models with a noise level of 30–40 dB. Approximately this level of noise has a human whisper.
Modifications equipped with the Nou Frost system work a little louder, which is associated with the use of a fan.
It would seem that devices with two motor compressors should work louder, since in this technique not 1 motor is preinstalled, but 2. But do not forget that in order to ensure normal cooling of the refrigerating and freezing chambers in a single-compressor refrigerator, it will be necessary to install a motor with a higher power . Accordingly, the 2 compressor representatives are still quieter.

And the last one. When a customer selects a suitable model in a specialized store, he does not hear the device’s operation. This is due to the fact that the mall and other stores themselves are noisy. Often the neighbors of refrigerators are plasma panels and LED-TVs, showing some content. For this reason, when you bring equipment home, install and connect it, you may be unpleasantly surprised by the increased noise level. That is why we do not recommend picking up equipment in stores “by ear”. All well-known manufacturers: Bosch, Beko, Indesit, Atlant, etc., without fail, indicate the noise level in the passport to the product. When choosing, it is better to focus on this indicator.
The new refrigerator is buzzing - reasons and what to do
The instructions for use indicate a small noise level, and your equipment is very noisy? Perhaps the reason lies in the improper installation of equipment. It is not allowed to have it close to the wall; The floor on which the equipment is installed must be level. In the next step, look inside the refrigerator. Perhaps you placed the products close to the walls? In this case, you can hear the ringing of metal utensils in cans. At the first connection, it will not be superfluous to make sure that the tubes do not contact each other. Otherwise, you will hear a noise.
Some users make the annoying mistake of forgetting to remove the transport bolts. As a result, the refrigerator is humming and very loud.

If the device has already been used for a certain time and suddenly began to work loudly, pops and fastens, we look for the problem further.
The refrigerator is noisy too loud: why is this happening
- The shock absorber mountings of the motor-compressor may become loose during operation. This creates noise, so the fact that the device rattles, rattles and buzzes is not surprising.Call the master or adjust the position of the parts, tighten the fasteners yourself. The problem will disappear.
- The refrigerant is noisy. This is not a malfunction. Freon circulates in the system at high speed and makes characteristic sounds.
- In refrigerators with No Frost technology, the fan blades make noise. But if the equipment began to make a lot louder noise than before, perhaps the ice around the blades of the knot froze. To get rid of the problem, it is enough to defrost the refrigerator.

The refrigerator clicks: it's a breakdown, why is this happening?
It goes without saying, if you hear clicks, the first thing that comes to mind is to check whether the device is working or not, whether there is sufficient cooling in the refrigerator and freezer compartment. The cause of this phenomenon also depends on this.
So, if you hear clicks, but at the same time the refrigerator works and normally cools, such sounds can occur due to narrowing-expansion of materials. The weeping type evaporator tubes or the housing plastic may crack. There is no malfunction in this. The design of the refrigerator provides for a slight deformation of the materials.
If your refrigerator clicks on and off (but it also works fine) - this is the sound of the thermostat. Some thermostats are too sonorous. Of course, you will hear such a sound from the first day of operation. Naturally, if this had not been observed before, and suddenly, for no reason, the thermostat began to click too loudly - this is not the norm.
Most likely, the reason is the loosening of the compressor mounts. If this is the case, do not postpone the repair, because further operation can lead to engine damage and, as a result, to expensive repairs.
If your refrigerator worked-worked, then it turned off, but can no longer turn on. The start relay clicks, but the engine does not start, possibly due to insufficient voltage in the household network. If your network is constantly sagging and the network has very low voltage or, on the contrary, there are frequent power surges, we recommend buying a transformer with a stabilization function. The device will provide the refrigerator with voltage with the desired characteristics, thereby ensuring the stable operation of refrigeration equipment.

If additional symptoms are added to the clicks: the compressor does not turn on, there is no cooling in the chambers, you are dealing with breakdowns. Let's look at what kind of malfunctions are associated with a similar problem.
Thermostat of an electromechanical refrigerator
- When you turn on the electromechanical type refrigerator, you hear clicks, but the compressor does not start. Most likely, there are problems with the thermostat. This sensor measures the temperature in the chambers. If it is insufficient, it sends signals to turn on the compressor. If the temperature has reached the set value - to turn off. The thermostat always clicks. But if, apart from the clicks, nothing happens, it has broken and will need to be replaced.
- When you turn on the refrigerator, clicks are heard. The compressor starts, but after a few seconds it stops. This indicates a malfunction of the motor. Due to a short circuit in the windings, the motor drones when it is turned on, it overheats. As a result of this, a protective relay is triggered and the equipment turns off. This assembly is not repairable.
- If clicks are heard periodically and the engine does not start, and the light does not turn on in the refrigerator, the problem is a start-up relay.
What to do if you encounter a problem? It is better to turn to the masters. In addition, it is not allowed to make changes to the design of the equipment yourself (even minor ones) if the warranty period of the service has not yet expired. Otherwise, you will lose the warranty.
Why does the refrigerator squeak even when the door is closed
In modern models, an alarm is provided with the door open.It works if the refrigerator is open for a long time. But if the squeak occurs with the door closed, something is wrong.
Store food in the refrigerator correctly.
So why is the refrigerator whistling:
- The door is not tightly closed. It is possible that food or utensils from the inside interfere with a snug fit.
- Loaded too hot products. For example, they cooked soup or stewed the roast, and, not waiting for the dishes to cool, put them in the refrigerator. Because of this, the temperature in the chamber rises sharply, the sensor recognizes this as an open door and alerts it with an appropriate signal. It is strictly forbidden to put unheated dishes in the refrigerator. Of course, situations are different. For example, you need to cook food for the whole family, and then immediately go to work - wait until everything cools down once, and without a refrigerator everything will disappear. But you need to find a way out of the situation. For example, ask them to put pans in the refrigerator later or not start cooking before leaving the house.
- The squeak is due to frost in the freezer. Because of this, the temperature sensor reads incorrect data. The problem is solved by defrosting.
- Also, the refrigerator can squeak until it reaches the desired temperature. This happens when you first turn on, as well as if there was a break in operation.
- A power surge has occurred. Try the following: unplug the plug, wait about 10 minutes, then plug the appliance back in.
The refrigerator beeps when the door is closed
If you follow all the recommendations for use, and the device still beeps, most likely there was a breakdown in the following nodes:
- Loose seal or wear of the rubber.
- Indicator failure.
- Malfunctions in the signal circuit of the indicator.
- Problems in the door position indicator. In this case, even with the door open, the light does not light.

How to turn off the sound
Attention! An alarm with an open door is a safety option developed by manufacturers specifically to extend the life of the equipment and ensure stable operation. If you hear a squeak, at least you need to figure it out. Muting is allowed if you are sure that there is no problem (for example, the device is gaining temperature).
