Often the food in the refrigerator covered with a thin layer of frost or even freeze, turning into icicles. Why does it happen? failures may occur in the work, responsible for regulation of the temperature regimes mechanisms.
Lowering the temperature in the refrigerator indicates malfunction in the unit. What to do in such a case? First we need to identify the reason for the failure has occurred. Adjust the temperature to the desired level or eliminate other faults can try yourself.
Before look inside the instrument cause mechanisms necessary to ensure the correct operation of the temperature controller. owners often are to blame for the fact that a strong frost refrigerator, and the internal temperature has dropped below an acceptable level. From this peremorazhivayutsya products. Often this is due to accidental pressing on the knob. Therefore, make sure that the regulatory lever is always in the center. An error tolerance for 1-2 division.
You need to rotate the crank a few times, because a failure could occur due to the fact that the regulator jammed spring.
In current models have an additional electronic menu, where a special regime responsible for superzamorozku Supercooling or placed in the refrigerator products. These modes can be established by default, and the walls will start the ice freezes. So check them and in which case, adjust manually.
Causes severe frost
The temperature regime in the cooling chamber can get off and other reasons. If regulators are normal, check the operation of additional mechanisms responsible for the operation of the temperature indicators.
the wear of the seal
On the refrigerator compartment doors have a special rubber gasket that eventually becomes unusable because of constant mechanical action. On the seal cracks, fractures, causing the warm air is supplied into the apparatus. Therefore refrigerator gradually lowers the temperature to compensate for the difference.
Because of this, the following happens:
- Camera start to frost up;
- is formed ice "coat".
As a consequence, gradually freeze all foods in the refrigerator.
Failure No Frost system
Most models are equipped with an automatic defrost system, with which the need for manual defrosting unnecessary. Samorazmorazhivanie occurs when the air sensor transmits a signal about the temperature decreases. If a sensor fails, the device receives incorrect information about temperature and continues to vigorously develop cold.
coolant leak
This arises as a result of gas emission from the host system. Therefore, the compressor starts to work strenuously, which affects the lowering of the temperature in the upper chamber art.
Blockage in the drainage system
This happens when plugging the drain hole. Accumulated condensate is not able to leave the refrigerator compartment, causing gradually accumulates in the bottom of the unit and the camera department freezes, turning into ice.
Broken air thermostat or sensor
Thermostat sensor or air are often broken due to contact with moisture or parts due to other mechanical damage. These elements are responsible for the correct display of the temperature in the refrigerating chamber. Because damage refrigerator receives no signals of temperature conditions, therefore it continues increasing cold.
Faulty valve
Detail is responsible for the temperature control and the relationship between the main card and the freezer. mode switching valve can sometimes sticky, causing violation occurs modes. The temperature in the freezing chamber becomes too high, and the main compartment is covered with ice.
If failure occurred in the temperature conditions of the refrigerator, eliminate breakage need as quickly as possible. Ignoring the problem can lead to increased operation of the compressor, which will trigger an emergency shutdown of all units.
In the case of damage, contact the service center if you do not have the experience and tools needed for such repairs. If you do not repair the parts at once, you can bring the technology to the major repairs, the price of which is not cheap. But what is more important - the risk of poisoning spoiled food increased in this case.
Easier to fix minor faults and defects in the work of the refrigerator, than to buy a new unit and allocate the money on it.
