refrigerator turns into a piece of ice products, layers of ice and snow on the walls of both chambers, frost even in the fresh area wherethe temperature should not fall below 2 degrees - all these symptoms indicate that the refrigerator is freezing too much. The reason for this phenomenon is not necessarily lies in the failure of the unit. Sometimes a problem arises due to the fact that its owner is concerned about the safety of products in hot weather and turns the temperature regulator to maximum. In such a situation, the compressor starts working for wear, as a result of which the refrigerator begins to freeze.
If this is the case, we can recommend changing the settings, setting the average value for the regulator, which will ensure reliable protection of food from summer heat. Otherwise, you will need to carry out diagnostics to identify the causes of incorrect operation of the device.
There are a number of malfunctions, due to which the refrigerator can freeze too much, blocking off whole ice hummocks on the walls. Below we look at all possible options, as well as troubleshooting methods.
Problem with sensors and temperature control
To deal with this problem, you will need minimal knowledge about the principle of operation of the refrigerator. In each of its cameras are installed special sensors. They constantly monitor the air temperature and, when it is raised or lowered to a certain limit, they send a signal to turn on or turn off the compressor. If one of these sensors fails, the temperature control stops, which leads to the following consequences:
- compressor starts to work without stopping, which can cause its rapid failure;
- , even when the temperature is correctly adjusted, the refrigerator refreezes food;
- intensive load over time leads to the failure of the motor-compressor.
If you set the thermostat to a middle position, but the engine does not turn off for a long time, do not expect the problem to disappear by itself. Contact the service center to diagnose and replace the sensor to restore normal operation of the refrigerator.
Violation of the tightness of one of the chambers and the formation of condensate
Low temperature in the chambers of the refrigerator is maintained due to the complete tightness of the chambers. She, in turn, is ensured by the presence of a rubber seal located on the door. With its normal wear or mechanical damage, warm air gradually begins to penetrate into the chamber.
To compensate for the lack of cold, the compressor begins to produce it much more actively, because of which there are layers of ice and frozen products. In addition, due to the excess heat in the chamber condensate forms, significantly increasing the level of humidity in the refrigerator. Replacing the seal and restoring tightness helps to solve both problems at once.
Clogging of the capillary system
To maintain the temperature in the refrigerator, refrigerant is constantly circulating through special tubes. But from time to time the capillary system becomes clogged, which is why normal circulation is not possible. Because of the arisen cork, freon cannot get into separate channels, which leads to a sharp decrease in temperature in one of the chambers.
How to fix this problem? The only reasonable solution is to clean the system, which will allow to restore the refrigerant circulation and its uniform distribution throughout the system. In single-compressor units, valve repair may also be required, which alternately directs freon either to the refrigeration or to the freezer and ensures their stable operation.
Problems with defrosting refrigerators
Modern refrigerators with the “No Frost” system are automatically defrosted without the need to disconnect the refrigerator from time to time to remove accumulated ice from it. This is due to the heating element, which emits enough heat for spontaneous defrost. If the device suddenly fails, the refrigerator will not be defrosted, which will lead to freezing of food.
In addition, in devices with “No Frost” it is recommended to periodically clean the drainage hole intended to drain excess moisture. When it is clogged, the refrigerator starts to freeze too much, and an unpleasant smell can appear in the chambers.
