1, the refrigerator compressor may be abnormal:
(1), the compressor running without refrigeration: may be the compressor high-pressure output buffer tube broken or fixed this tube screws loose, resulting in high-pressure tube does not exhaust the low-pressure tube does not suction, so the compressor is running, but not refrigeration.
(2), the compressor does not turn: may be air conditioning compressor starter damage, should be replaced in a timely manner with a new compressor starter.
2, refrigeration system leakage, refrigerant run out:
The compressor is running but no refrigerant evaporation in the system to absorb heat, so the temperature inside the refrigerator does not fall, the refrigerator will not cool the phenomenon. Refrigerant should be replenished in time.
3, the capillary tube in the blockage, the refrigerant can not enter the evaporator in the evaporation of heat absorption, so the temperature inside the refrigerator does not fall.
