Causes and solutions of no refrigeration in air-cooled refrigerator

1. Reason 1: The indoor temperature of the refrigerator is too high, which leads to the leakage of fluorine in the refrigeration system, that is, the refrigerator does not cool because there is no refrigerant.

Solution: Find a repairman, re-weld the pipeline, and take the time to refill the refrigerant.

2. Cause 2: The evaporator is frosted. The main air-cooled refrigerator has only one evaporator. If the frost on the evaporator doesn't melt, it blocks the air duct, and the cold energy can't get out, resulting in no refrigeration in the refrigerator.

Solution: Check the defrosting system. There may be something wrong with the defrosting timer, or the heating pipe is burnt out.

3. reason 3: the refrigerator has been used for a long time. If there is a leak in the pipeline or evaporator, it is useless to add fluoride alone.

Solution: it is difficult to repair, and it is necessary to find the leakage point for repair, but it will not last long.

4. Reason 4: There is something wrong with the refrigerator compressor. The compressor can't be started because of the low pressure of the compressor return pipe, which leads to the refrigerator can't be cooled.
