It’s great when the refrigerator works without breakdowns. But when it doesn’t turn off at all, this is no longer normal. The motor compressor will not stand long work without a “respite”, its parts will wear out and fail. What to do if the freezer does not turn off? Find out the causes and start troubleshooting.
Why does the freezer constantly work
Are you sure that the compressor does not stop to rest? Normally, the refrigerator should function for 20 minutes and rest for 5 minutes. Listen to work: if it really works without stopping, then start looking for reasons.
If the Biryusa or Indesit freezer is constantly working, this does not mean a serious malfunction. First of all, you need to check:
- Which mode is selected. Maybe you turned on super freezing so that after washing the compressor will catch up to temperature faster. In electromechanical models, the established mode must be disabled independently: it is enough to turn the knob of the regulator. Whereas in electronic, it turns off automatically after two to four hours.
- Thermostat position. For devices with mechanical control, the normal position of the regulator is 2.5-3.5. For electronic equipment, choose a temperature of -18-19 degrees. Even when the room is hot and stuffy, you do not need to set a larger value. If you have chosen the right equipment for the climate class, it will cope with the load.
Important! The climatic class is indicated by Latin letters on the case or in the instructions for the device. Choose depending on the region and place of operation.
If all indications are normal, but the freezing section does not turn off, then diagnostics of units and parts is needed. You can contact a specialist or try to fix the problem with your own hands.
Malfunctions that require repair
The causes of such breakdowns must be sought with the help of special equipment. Therefore, if you do not have such experience, it is better to contact the service. At least you will understand where to look for the problem.
The engine buzzes without shutting down, but there is no cold in the freezer compartment
The reason is the clogging of the capillary pipeline: as a result, the refrigerant cannot move normally along the circuit. Blockages can occur due to burnt compressor oil particles that also travel through the system.
What to do:
- Clean the circuit system.
- Check engine oil. Replace if unsuitable for use.
- Fill the system with freon gas.
The camera freezes so that ice and snow build up on the walls
In electromechanical models, the problem may lie in the temperature controller. In electronic refrigerators, the evaporator sensor (Indesit, Ariston, and other brands with Nou Frost) could break.
Since the thermal relay does not send a signal to the board about the temperature in the compartment, the board does not give a signal to shut off. Therefore, the motor runs without interruption.
To fix the problem, you need to replace the sensor or thermostat.
Also, the problem may be the constant ingress of warm air into the chamber. For what reason does this happen:
- The door seal was worn. Check if it is dirty, so it does not adhere to the case. Wash it with soapy water, wipe with ammonia. If the rubber is deformed, boiled water will help to restore its shape. To do this, water the seal with a thin stream. When worn out, a complete replacement of the element is needed.
- Hinges sagged, loosened door fasteners. Tighten fasteners or replace doors.
In a refrigerator with one engine, the freezer freezes, and in the refrigerator section the temperature is elevated
Possible reasons:
- The switch is stuck in one position. The valve switches the supply of cold to the upper and lower chambers alternately. If it sticks, one of the cameras does not receive proper cooling. Parts are being replaced.
- The electronic board is out of order. Then the motor does not receive a command and does not turn off.
In models with two engines, the freezer section freezes food; the refrigeration department works as usual
The module is again diagnosed and replaced.
The freezer works without stopping, but the temperature does not reach the set
The point is the refrigerant outlet: somewhere the circuit is broken, and the gas flows out. To confirm the guess, defrost the appliance and leave it to stand for 24 hours. Then plug in the network. If the refrigerator or freezer does not turn on, there is a leak.
If Freon leaks, call a wizard who will find the leak, fix the problem and refuel the system.
Now you know where to look for a problem in case of such problems. Do not allow prolonged operation of the equipment without stopping, otherwise you will have to carry out expensive repairs.
