1. Improper adjustment of the expansion valve and drain valve of the preservation cabinet, excessive refrigerant in the system, air in the refrigeration system, poor sealing of the valve plate assembly, and wear of the piston of the compressor cylinder liner. 2. The high-pressure output buffer tube in the compressor is broken, the screw fixing the tube is loose, the high-pressure tube does not exhaust, and the low-pressure tube does not inhale, so the compressor runs, but does not refrigerate.

2. The high-pressure output buffer tube in the compressor is broken, the screw fixing the tube is loose, the high-pressure tube does not exhaust, and the low-pressure tube does not inhale, so the compressor runs, but does not refrigerate.

3. The refrigeration system leaks, all the refrigerant leaks, and the compressor runs, but because the refrigerant evaporates without absorbing heat, the temperature in the cabinet will not drop.

4. The capillary tube is blocked, the refrigerant enters the evaporator to evaporate and cannot absorb heat, and the temperature in the cabinet will not drop.

5. Due to welding or improper use of the fresh-keeping cabinet, the refrigeration system has a leak point, and the refrigerant in the freezer in the refrigeration system leaks within a certain period of time and is not frozen.

6. Check whether the offset of the fresh-keeping cabinet is correct. The difference of offset affects the power consumption and temperature of the refrigerator.
