The freezer does not turn off: why, what to do

It’s great when the refrigerator works without breakdowns. But when it does not turn off at all, this is no longer normal. The motor-compressor will not withstand long-term 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 keep running

Are you sure the compressor is not stopping to rest? Normally, the refrigerator should function for 20 minutes and rest for 5 minutes. Listen to the work: if it really works non-stop, then start looking for reasons.

If the Biryusa or Indesit freezer is constantly running, this does not indicate a serious malfunction. First of all, you need to check:

• Which mode is selected. Maybe you turned on superfreeze so that after washing, the compressor catches up with the temperature faster. In electromechanical models, the set mode must be turned off independently: just turn the knob. Whereas in electronic it turns off automatically after two to four hours.

• Thermal relay 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 higher value. If you have chosen the right technique for climate classshe can handle the load.

Important! The climate class is indicated in Latin letters on the body or in the device manual. Choose according to region and location.

If all indications are normal, but the freezing department does not turn off, then diagnostics of components and parts are needed. You can contact a specialist or try to fix the problem yourself.

Problems 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 know where to look for the problem.

The engine hums without shutting off, but there is no cold in the freezer compartment

The reason is the blockage 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 move through the system.

What to do:

• Clean the circuit, system.
• Check engine oil. Replace if it is not usable.
• Fill the system with freon gas.

The chamber freezes so that ice and snow grow on the walls

In electromechanical models, the problem may lie in the temperature controller. In electronic refrigerators, the evaporator sensor could break (Indesit, Ariston and other brands with No Frost).

Since the thermostat does not send a signal to the board about the temperature in the compartment, the board does not send a signal to shut down. Therefore, the motor runs without interruption.

To fix the problem, you need to replace the sensor or thermostat.

Also, the problem may be in the constant ingress of warm air into the chamber. Why is this happening:

• Worn door seal. 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 restore its shape. To do this, water the sealant with a thin stream. When worn out, a complete replacement of the element is necessary.

• Hinges sagged, door fasteners loosened. Tighten fasteners or replace doors.

In a refrigerator with one motor, the freezer overfreezes, and in the refrigerator section the temperature is increased

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 chambers is not getting proper cooling. The part is being replaced.
• The electronic board has failed. Then the motor does not receive commands and does not turn off.

In models with two motors, the freezer section refreezes food, the refrigeration unit operates in the usual mode.

The module is diagnosed again and replaced.

The freezer runs non-stop, but the temperature does not reach the set temperature

The point is the release of the refrigerant: the circuit is broken somewhere, and the gas flows out. To confirm your guess, defrost the appliance and leave it to stand for 24 hours. Then turn on the network. If the fridge or freezer won’t turn on, it’s a leak.

In the event of a freon leak, call the master 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 the equipment to work for a long time without stopping, otherwise you will have to carry out expensive repairs.
