Why doesn't Meiling refrigerator cool at MINUS 5 degrees?

Generally speaking, the main reasons why refrigerators don't cool are:

1, compressor running but not cooling: the high-pressure output buffer tube in the compressor is broken, or the screw fixing this tube is loose, resulting in the high-pressure tube not exhausting and the low-pressure tube not sucking air, resulting in the refrigerator not cooling;

2, refrigeration system problems: the refrigerator refrigerant leaks or lacks fluorine, no refrigerant evaporates to absorb heat, and the refrigerator temperature does not drop, so it cannot be cooled;

3. Capillary blockage: evaporator frosting. Generally speaking, an air-cooled refrigerator has only one evaporator. When the evaporator is frosted and cannot be melted, the air outlet is blocked, and the cooling capacity cannot go out, resulting in the refrigerator being unable to cool.

Common solutions:

1. Check the compressor: you can check whether the motor coil is burnt out, and finally check the condition of the starter. Sometimes the overheat protector is working, and the compressor needs some time to cool before it can be started;

2. If the refrigerant is short of fluorine or leaks, it is recommended to call the official after-sales phone for maintenance and add refrigerant;

3. Check the defrosting of the evaporator to see if the defrosting timer is faulty. If problems are found, contact after-sales service in time;

4. In daily life, check the common functions of the refrigerator regularly, and contact the after-sales department in time when encountering problems, so as not to affect the normal use in the later period.
