1, the temperature of the refrigerator is too low. 2. The door seal is not tightly sealed or the door is opened frequently or for too long, which leads to serious loss of cold air in the refrigerated room. 3. The freezer freezes because there is an evaporator on the back of the freezer liner, and the temperature of the freezer mainly depends on the evaporator to reach the set temperature.

Suggested treatment:

1. If the sealing strip is not tight, replace it with a new door seal, and try to reduce the number of times or time to open the door at ordinary times.

2. Fix the loose temperature sensor so that it is in close contact with the evaporator in the back wall of the refrigerator.

3. If the internal contacts of the thermostat are stuck, separate the contacts first, then adjust the gear to 1-2, and then turn on the power supply for commissioning after 5 minutes of power failure. If the compressor can be stopped, it means troubleshooting.

Reduce opening and closing doors. The best way to reduce the freezing is to reduce the humidity in the air inside the refrigerator. Therefore, in summer and in humid areas, reducing the number of refrigerator doors is one of the best ways to reduce the freezing inside the refrigerator.

4, fresh vegetables and fruits sealed storage. Because of normal metabolism, fresh vegetables and fruits will constantly emit moisture. Therefore, when we store these fresh ingredients in the refrigerator, we need to seal the food to reduce the moisture in the food from entering the air.

5. Don't pile too much food in the cold room. Usually, try not to put too much food in the refrigerator, and pay attention to the distance between the food and the back of the refrigerator.
