Why is the refrigerator always hot?

The refrigerator is always hot, usually caused by excessive internal temperature or mechanical failure. Here are some possible reasons:

1. Improper temperature adjustment: proper gas needs to flow between the condenser and evaporator of the freezer to maintain the temperature. If the temperature is not properly adjusted, too much gas will flow into the condenser and cannot flow back to the evaporator, thus causing the condenser to heat up.

2. The fan doesn't work normally: The fan in the freezer is used to send the refrigeration gas circulation back to the evaporator to keep the temperature in the refrigerator adequate. If the fan does not work properly, it will cause the temperature of the front refrigerator to rise.

3. Circuit board failure: The control circuit board of the freezer may fail, making it unable to control the refrigeration cycle properly. In this case, the refrigeration cycle gas will flow to the wrong area, resulting in overheating of some components.

4. Incomplete cleaning: If the refrigerator is not cleaned regularly, dust, grease and other substances may hinder the normal operation of the refrigerator. These deposits will hinder the refrigeration cycle and eventually lead to overheating.

5. Refrigerant leakage: If the refrigerant in the refrigerator leaks, air will enter the refrigeration system and form an airbag. In this case, the remaining refrigerant cannot be circulated, forcing the refrigerator to overheat.

In short, there may be many reasons why the refrigerator is always hot, so it needs to be thoroughly checked to determine the cause of the failure and carry out maintenance. If necessary, it is best to recruit professionals.
