If the refrigerator power supply is not the cause of electricity, reconnect the power supply can be; if the compressor failure, replacement or repair of the compressor can be; if it is the snow leakage, drain the leakage point, and then add the snow can be; if it is a fan problem, repair the fan can be.1, power problems, sometimes not the use of the problem, not the quality of the refrigerator, it may be the power supply problem, to check the power supply is connected to whether the normal. Open the door, observe the box lighting is lit, or use the electric pen to test the socket has no electricity. 2, the compressor problem, if the power supply is connected to the normal, test the compressor is working. Compressor normal work will emit a slight vibration motor sound, such as the hand to feel the vibration of the compressor, you should pay attention to don't burn, because the compressor temperature in the winter 40-50 ℃, summer can reach up to 80-90 ℃. 3, the refrigerant leakage, if the compressor can work, judge the refrigeration system with or without refrigerant. Let the refrigerator run for a few minutes after unplugging, listen carefully to the sound of liquid flow in the copper tube. If not, it means that the refrigerant in the system has leaked, or the compressor has lost the ability to work. It will be necessary to increase the refrigerant.
