Several possible reasons and elimination methods of refrigerator not cooling

1, the refrigerator voltage is normal, but the compressor can't operate normally, with noise and rotating sound. Once the compressor fails, the refrigerator can't be cooled, so it is necessary to ask professional maintenance personnel to replace the compressor. If the fuse of the compressor is blown, first replace the fuse of the refrigerator, and then cool the compressor to avoid secondary blowing. If the life of the refrigerator has reached the age of replacement, get a new refrigerator.

2. Insufficient refrigerant

The refrigerator is short of refrigerant, and it is most likely that the condenser tube of the refrigerator fails, resulting in refrigerant leakage. At this time, a professional maintenance master needs to come to the door for maintenance, then repair the condenser pipe and add an appropriate amount of refrigerant.

3. The filter screen is blocked

The function of the filter screen is to absorb impurities, but after a long time, there will be a lot of impurities on the filter screen, which will increase the operating burden of the refrigerator and lead to abnormal operation. Therefore, the poor refrigeration effect of the refrigerator may be the blockage of the filter screen. It is best to clean the filter screen every once in a while.

The air outlet is blocked.

The refrigerator is really not the more food, the more stuff, the better. Once the refrigerator is full, you will find that the air outlet of the refrigerator will also be blocked, which will make the food unable to keep fresh.

5, thermostat failure problem

The thermostat of the refrigerator controls the temperature. Once the thermostat breaks down, the refrigerator won't cool. The thermostat of refrigerator is mostly installed in the cold room. If the temperature of the refrigerator can't reach the temperature of the thermostat, it will always be in operation. As long as the compressor does not stop, the temperature of the freezing room may be very low, which may lead to the frost freezing of the evaporator in the refrigerating room, thus causing ice blockage.
