There are situations when the refrigerator does not freeze, but the compressor is constantly running. The normal operation of the equipment is considered to be a motor shutdown every 15-20 minutes. If it works for more than an hour - time to sound the alarm.
We will give examples of common problems in the refrigerator, tell you how to determine the breakdown, what signs to look for.
Why does the compressor run without stopping
If the refrigerator motor has been running for a long time and is noisy, the cause may be minor issues. First defrost the equipment during the day. The refrigerator did not start working normally? Then check:
- Correct installation. When the refrigerator body is mounted close to the wall, battery, gas stove, ventilation is not enough, overheating occurs. The engine runs loudly and without interruption, trying to compensate for the temperature increase. Therefore, it is important to maintain a distance of 7-10 cm between the body and other objects.
- The closure density of the chamber door. Perhaps the compartment shelves are overloaded, which prevents the door from closing normally. The cause may be an unsuitable seal or a loose hinge.
- Is the superfreezing mode on the Atlant, Indesit refrigerator with mechanical control turned on? The engine cannot turn itself off until you turn off the mode yourself.
After checking it turned out that everything is in order? So, the matter is in breakdowns requiring repair.
Door seal worn. The elastic should fit snugly against the body. If this does not happen, warm air enters the compartment, which leads to non-stop operation of the motor. The seal must be cleaned or replaced.
Thermostat or temperature controller is not working properly. Modern refrigerators are electromechanically controlled, all processes in the system are controlled by the main module. If the temperature information in the chamber does not come from the sensor to the module, then the board does not give a command to turn off the compressor.
Defective electronic module. Therefore, some nodes may not work correctly.
Refrigerant reduction. Due to the leakage of cooling gas, it is not enough for normal operation of the equipment. The cause of the leak is eliminated, after which the system is charged with refrigerant.
Compressor running for wear. When the engine loses operating power, the pressure in the discharge pipe does not reach a predetermined level, so cooling does not occur.
Refrigerator compressor not working: causes of breakdown
Everyone is used to the fact that the refrigerator is noisy when the engine starts. But if there was silence, and in the departments a complete “thaw”, take up the search for a malfunction.
How to proceed:
- open the camera door, see if the light is on;
- if there is no light, check the wiring and cable for damage;
- if the light is on in a new refrigerator (LG, Stinol), you need to check the location of the case. In case of leaky closure, warm air enters the chamber, so the motor does not start.
More serious failures require diagnosis and repair:
- The compressor burned out. It is audible how the engine tries to start, but is immediately turned off; the relay clicks, but does not give a result. The motor needs to be replaced.
- Faulty thermostat. Lighting in machinery with mechanical control ("Minsk", "Biryusa") can work, while the compressor has stopped turning on. The module does not receive temperature data, so it does not start the motor.
- Damage to the temperature sensor in models with an electronic system leads to similar consequences.
- The start relay, which is responsible for turning on the compressor, has broken or jammed. Parts are being repaired or replaced.
- Defective electronic module. Two compressors may not work at the same time. Since the operation of the equipment is impossible without a module, a flashing is carried out.

The refrigerator does not work, but the compressor is hot
How long should the compressor run in the refrigerator? As mentioned above, the motor should shut off 3-4 times in an hour. All breakdowns overlap with each other, although they have different signs. Why does the compressor heat up?
- Look, maybe you didn’t turn off the Super Freeze mode. It is used to quickly freeze vegetables and fruits, while the engine is constantly running, pumping cold. If the function is turned off at the wrong time, it overheats.
- The start relay is jammed, so the trip does not work.
- Damaged chamber wall or sealing rubber. This causes warm air to enter the chamber, so the refrigerator freezes without stopping.
- There is a refrigerant outlet.
- As a result of overvoltage, the control board burned out.
The reasons that the technique does not chill may be more commonplace. By putting a hot dish in the compartment, you doomed the motor to permanent operation. This negatively affects the details and components of the refrigerator.
Read the instruction manual carefully, do not avoid the rules described there. So you will help the technique to last for many years.
