What is the reason why the refrigerator gets hot

Heating on the side of the refrigerator is normal. Since the refrigerator needs to release the heat generated by the compressor during the working process, mainstream refrigerators will choose to release the heat from the side and back of the refrigerator, so the user will feel a certain amount of heat when touching the side of the refrigerator. It should be noted that if heat on the side of the refrigerator increases sharply, check whether the refrigerator door is not tightly closed and whether the temperature difference between the inside and outside of the refrigerator is too large. The following is a detailed description of abnormal heating on the side of the refrigerator:

1. The refrigerator door is not tightly closed causing excessive heat on the side of the refrigerator. If the refrigerator door is not tightly closed, the temperature in the refrigerator gradually rises, and the refrigerator compressor needs to work continuously to reach the user preset room temperature. In the long run, the increase in compressor workload will increase heat generation. In this case, it is recommended that the user disconnect the refrigerator power supply to temporarily schedule the compressor to work, and close the refrigerator door tightly or replace the sealing ring, and wait for the side temperature of the refrigerator to decrease before using it.

2. Excessive temperature difference between the inside and outside of the refrigerator causes excessive heat on the side of the refrigerator. If the temperature outside the refrigerator is 30 degrees Celsius and the temperature inside the refrigerator is set to minus 7 degrees Celsius, there is a considerable temperature difference between them. The compressor also needs to increase work to maintain the temperature to a preset level, resulting in increased compressor load and severe heat generation. It is generally recommended that users set the refrigerator temperature at 2-7 degrees Celsius in summer and 0 degrees Celsius in winter.
