For what reasons may the freezer not freeze?

Faulty freezerThe freezer, like any electrical appliance, is susceptible to malfunctions. However, incorrect operation of the device does not always indicate a breakdown. Sometimes this is a consequence of improper operation that can be easily and immediately corrected, which can be extremely important for the safety of food placed in the freezer. What are the possible reasons for the malfunction of freezing devices or their operation in a broken cycle?

The freezer does not freeze: reasons

If there is any malfunction in the functioning of the freezer, immediate action should be taken to correct the problem. Timeliness and correctness of actions are important.

Freezer won't turn on

In this case, first of all it is necessary to check the electrical network. If the socket is working - the light bulb that receives power from it is on, and the indication lights up when the device is plugged in, you can proceed to diagnosing the cooling system.

ATTENTION! Check the operating mode of the unit; it must be turned on for freezing.

Next we move on to the thermostat. If it is stuck in the off state, the electrical circuit will not close and the chamber will not begin to get cold.Replace the failed unit yourself, or call a service engineer.

The next step is to check the compressor motor. If for some reason it has become unusable, you must first replace it and then determine what could have caused the breakdown. If the freezer is quite old, the compressor may have simply reached the end of its life.

The freezer is not freezing, but it is on

There are many reasons why the freezer, when turned on, does not freeze well. Let's start with those that are easy to fix due to the absence of breakdowns as such.

  1. A large amount of content with high heat capacity is loaded into the chamber. For example, you decide to freeze a lot of meat at once or cool the water. The amount of heat that needs to be removed is directly proportional to the temperature difference (current and target), the specific heat capacity of the product and its mass. If the last 2 factors are significant, the device may not have enough cooling power. You will need to unload the chamber and fill it gradually, as the previously placed content freezes.Why is the freezer not freezing?
  2. The same thing will happen when too warm products are loaded - the cooler will not be able to cope with the removal of excess heat. The way out of the situation is to pre-cool the product naturally or in a refrigerator.
  3. Check the operating mode, it may have been accidentally disabled.
  4. The reason that the device does not freeze may be its forced shutdown by the thermal protection relay. It is triggered when too much current passes through the compressor motor winding, causing the conductor to overheat.This can happen when the refrigerator is running for a long time or when it overheats outside. Your actions are to remove the camera from the area of ​​direct sunlight and ensure the necessary convection, if necessary, moving the device away from the wall.
  5. The seal of the door is broken - close it more tightly; if this is not possible, you will most likely have to replace the seal.
  6. The freezer opens too often, resulting in constant heating of the chamber - change the access mode.
  7. Formation of a large amount of ice on the chamber evaporator. In this case, the ice will prevent the cold from spreading inside and the temperature in the area where the sensor is located will not reach the set level. To prevent serious damage, you need to defrost the camera.
  8. Exceeding the temperature range corresponding to the climate class of the device - turn on the air conditioner, ventilate the room, or take other measures to reduce the outside air temperature to an acceptable level.

The following reasons indicate a device failure that requires repair work.

ATTENTION! Not only minor, but also quite serious faults can be identified independently.

The formation of so-called thermal bridges in the insulating material of the equipment casing between the outer and inner walls can lead to parasitic release of precious cold to the outside. This occurs due to moisture penetrating inside the casing. To eliminate this defect, it is necessary to replace the area of ​​wet thermal insulation and seal the housing.

The tightness of the refrigerant circulation is broken - there is not enough carrier to eliminate thermal energy from the chamber to the outside.The malfunction is determined by adding dye to the refrigeration circuit. In this case, it is necessary to eliminate the leak and top up the system with freon. Such an intervention can be carried out manually only if you have the skills and special tools.

Clogged capillary tubes will also cause the freezer to be unable to get cold. It occurs during prolonged use without prevention. To fix the problem, you need to drain the refrigerant, change the oil, clean the system and refill it with freon.

If the compressor is faulty, the motor of the chest freezer or cabinet will work, however, by itself, no cooling effect will be observed in the chamber. The faulty unit needs to be replaced.

Another possible failure that affects the intensity of freezing is the failure of the fan that removes excess heat from the condenser radiator. The unit will operate in continuous mode without the required heat exchange. The repair in this case is quite simple and not expensive - replacing the fan.

Freezer won't turn off

Freezer won't turn offThe freezer will operate continuously if the temperature sensor does not sense the required temperature level has been reached. Therefore, all the faults mentioned above (with the exception of an incorrectly set mode) can lead to the camera not turning off, provided that the motor thermal relay does not reach the temperature at which a forced shutdown occurs.

Another reason for the constant operation of the refrigerator may be a breakdown of the sensor, thermostat or safety thermostat. In this case, the problem can be solved by identifying the failed element and replacing it with a working part.

The freezer turns on and then turns off immediately

If your freezer turns on for a few seconds and then shuts off, this may be a symptom of a problem with the condenser.

It is also possible that the error is related to a problem in the motor. If its power is not enough and it constantly overheats, a shutdown will occur when the thermal protective relay is triggered. Alternatively, try to provide more intensive cooling of the motor, but most likely it will have to be changed.

A quick shutdown of the device after a short-term switching on may indicate a malfunction of the control unit.

Comments and feedback:

My freezer didn't freeze because the door didn't close tightly.
