Causes of malfunctions of individual refrigerator models

It is hard to imagine a modern kitchen without a uniform rumbling of a refrigerator. This is perhaps one of the indispensable attributes of a modern home. Therefore, any signs of damage cause anxiety to the owners. One of the most common questions is why did the refrigerator start clicking? Let's try to figure out whether it is urgent to take the equipment for repair or is it a design feature.

Start of diagnosis

First of all, you need to see if the refrigerator turns on and does it hold the desired temperature. Three options are possible:

the refrigerator turns on, the motor runs, the desired temperature is reached;
the refrigerator turns on, there is a sound of the motor, but the desired temperature is not achieved;
the refrigerator does not turn on, the motor does not start.

In the first case, most likely, the clicks are associated with the deformation of the plastic parts during heating and cooling. This is a design feature that should not be disturbing. The clicking sound may be emitted by the temperature sensor. Some models are initially more “noisy” than others.

Worse if the refrigerator "does not chill" or the engine does not start at all. In this case, you can’t do without contacting the master. We consider all cases in more detail.

No worries

There are two main reasons for the refrigerator to click during operation, which do not affect its performance.

Plastic parts and tubes when heated and cooled change in size and deform, making unusual sounds. In this case, clicks will occur immediately after turning the unit on and off. The developers took such deformations into account, so they usually do not lead to breakage.
Clicks may accompany the operation of the thermostat. Some models initially make loud sounds. This is your option, if the new refrigerator began to crack from the very first day of operation.

If previously the equipment worked quietly, and now it clicks during operation or starts clicking very loudly compared to previous periods, you will need to contact the workshop.

Malfunctions

Here are the main problems due to which the refrigerator pops or clicks.

Symptom	Malfunction	Repair Needed
When you turn on the motor does not start, the refrigerator constantly clicks. The light in the camera is off.	Start-up relay failed.	It is necessary to replace the relay with a new one.
The lamp in the camera is on, but the motor does not start. The refrigerator periodically makes clicks.	The thermostat broke, which should give the motor a signal about the temperature difference. This part can click and in working condition - then at breakage the sound becomes louder. The Indesit and Ariston refrigerators are most susceptible to this problem.	Replacing the thermostat (temperature sensor).
When you turn on the unit makes a click, the motor starts to work, but immediately turns off. At the same time, a loud click is most often heard again (a start-up protective relay has tripped), but the equipment may turn off quietly.	The motor-compressor broke down - the main unit of the unit. He tries to start work, but then overheats. The protective relay makes an emergency stop.	Compressor replacement.
The equipment turns on, it works fine, a click is heard when it is turned off.	The compressor mounts loosened. This happens if the refrigerator is not installed at the level. Vibrations during operation weaken the mounts, and the motor starts to knock on the walls of the body when stopped. Most often, problems with the motor occur in Atlant refrigerators.	There are two possible solutions to the problem: install the refrigerator according to the level or adjust the mounting springs. The second method is preferable, since an incorrect position of the motor can lead to its breakdown.
After switching on, the unit first clicks several times, then the motor starts and then works normally: the light in the camera is on, the temperature is kept at the right level.	Low voltage. The motor is trying to start, but the voltage is not enough. Therefore, the relay emits characteristic clicks. Start-up attempts continue until the compressor is running.	It is necessary to tidy the wiring and purchase a voltage stabilizer. If a jump occurs during operation, the unit may break.

You can fix the problems yourself, but it is better to use the help of professionals. Refrigerators and parts for them cost a lot, and it will be a shame if the equipment breaks completely due to inept actions. In addition, now it is not necessary to give the unit to the workshop. The master will perform all necessary actions at home.

Causes of malfunctions of individual refrigerator models

In the comparison table - features of the most famous brands of household appliances and the main causes of clicks.

Brand of refrigerator	Features	Malfunction	Cause
Atlant	Available equipment of Belarusian production. The quality of the parts is good, but often there are problems with the mounts.	The most frequent failures: relay failure, loosening of motor mounts.	Initially weak fasteners, low margin of safety of "native" parts.
Bosch	One of the most reliable refrigerators.	The most common problems are with the thermostat and compressor.	Problems arise due to problems in the mains or equipment wear.
Indesit	Good technique, but there are some “weaknesses”. For example, not the best quality door seal, which is why the temperature in the chamber rises and the load on the motor increases. In models with the “Know Frost” function, the appearance of an ice “coat” on the walls, which interferes with air circulation, is not excluded.	Failure of the thermostat, fan, relay, compressor.	Power surges and “weaknesses” - poor seal and frost on the walls. In these cases, the load on all nodes increases, and the equipment quickly fails. Therefore, the owners of Indesit refrigerators need to monitor the condition of the seal and change it in a timely manner.
Liebher	Premium class refrigerators - the highest quality, the best materials, energy saving, unique design, lots of functions. Strict control at the factory eliminates factory defects and low-quality components.	Failure of the relay, compressor, loosening of the compressor springs.	The main reason is improper operation. Most often, the equipment suffers due to improper installation and power surges.
Samsung	High-quality and reliable equipment. The likelihood of factory defects is minimized.	Damage to the compressor, relay.	Breakdowns usually occur due to power surges.
Hotpoint Ariston	Equipment equipped in accordance with the latest technology. Ice displays, touch panels, sophisticated electronics are characteristic features of this brand.	Thermostat breakdowns, motor failure.	Failures arise due to the rapid wear of the "native" parts.

Like any appliances, refrigerators sometimes break. If you notice oddities in the operation of the refrigerator (clicks, crackles, extraneous sounds, or something else), do not wait for the final breakdown. If you contact the master on time, repair will be easier and cheaper. Contact specialized service centers, then the equipment will last for many years.
