1, probably because the refrigeration pipeline of the refrigerator is too close to the inner container of the refrigerator, and the refrigeration pipeline is too close to the inner container, which will cause icing.

2. It may be that the food in the refrigerator is too close to the inner container of the refrigerator. If the condenser of the refrigerator is on both sides of the refrigerator, it will cause the refrigeration pipeline of the refrigerator to freeze.

3. It may be that the temperature control gear of the refrigerator is adjusted incorrectly. Improper adjustment of the temperature control gear will cause the cold room to run water and freeze. Generally, the larger the scale number of the thermostat, the lower the temperature of the refrigerator will be, and then it will freeze.

4. The thermostat is out of order. If the thermostat is out of order, the temperature change can't be accurately sensed, and the temperature in the freezer of the refrigerator will be lower and lower, which will lead to freezing. The thermostat is broken, and the compressor can't get the temperature of the refrigerator, so it will keep working, causing icing.

Solution:

1, first melt the ice in the refrigerator, and then put a layer of cooking oil on the inner wall of the freezer, which can effectively prevent the freezer from freezing. It is best to use vegetable oil, which has a low freezing point. If you don't use oil, it is also possible to use plastic wrap.

2. Turn off the power supply of the refrigerator, put a large bowl of warm water (don't use boiled water) in the freezer, and change the water after about 10 minutes. This method can melt the ice in the freezer more quickly.

3. After the ice in the refrigerator melts, dry the ice water with a clean cloth. After cleaning, you can stick the plastic film on the inner wall of the refrigerator. The next time we remove the plastic film from the inner wall of the refrigerator, it will be done. Plastic film mainly plays a role in separating food from refrigerator wall.
