1, the defroster in the refrigerator is broken, and the ice in the refrigerator can't be cleaned up in time, which will cause ice blockage in the refrigerator, which will cause the refrigerator not to cool. 2. The failure of the fan in the refrigerator makes the refrigerator unable to dissipate heat in time. There is also more food in the refrigerator, which blocks the air outlet, which will lead to the cooling effect of the refrigerator getting worse and the temperature inside the refrigerator rising slowly, so it will not cool slowly.

Suggested solution:

1 If the refrigerator is not cooled, the main reason may be that the compressor is not working. At this time, it is necessary to open the fresh-keeping cabinet above the refrigerator. There is gear adjustment on it. Some refrigerators are low-grade, medium-grade and high-grade. Some refrigerators display the degree. In winter, you need to adjust the refrigerator to the high-end position, but in summer, you just need to adjust it to the lowest position.

2. If the fan of the refrigerator fails, it needs to be repaired, and in serious cases, it needs to be replaced. At the same time, it is also reported that the air outlet of the refrigerator should be unblocked, so as to improve the heat dissipation effect of the refrigerator and reduce the internal temperature of the refrigerator.

3. Re-adjust the thermostat of the refrigerator. In summer, the thermostat gear of the refrigerator needs to be lowered, while in winter, the thermostat gear needs to be raised. In winter and summer, the thermostat gear adjustment is just the opposite.
