Freezers are widely used in our daily life, and due to external and internal factors such as improper use or poor quality, freezers will have a series of failure problems.
If the compressor stops after starting the freezer, the first thing to check is the cooling condition of the freezer. If the cooling effect of the freezer is normal, the freezer is normal. The reason for this phenomenon may be that the temperature inside the freezer is set too high. The internal temperature has reached the set temperature, so the compressor will stop after starting; if the freezer is not cooling, check one by one according to the following methods:
4. If the compressor of the freezer is turned off, it will not refrigerate. Check the thermostat of the freezer. First unplug the power supply of the freezer, then adjust the number of the thermostat to the maximum value, and then plug in the power supply to observe whether the compressor of the freezer starts running. If the compressor of the freezer is running, there is no problem with the compressor. If the compressor does not run, it means that the thermostat is damaged.
5. If the refrigerator compressor starts and stops and does not cool down, it may be caused by the damage of the starting relay. If the motor resistance of the refrigerator compressor is normal with a multimeter, the thermostat is in good condition, and the overload protector has no abnormal phenomenon, it should be inside the starting relay of the refrigerator. If the fault disappears, it can be judged that the start relay of the freezer is damaged.
6. If the freezer compressor starts and stops and does not refrigerate, it may be caused by the defective overload protector in the freezer. Use an ammeter to measure whether the starting and running current of the freezer compressor is normal. If the overload protector does not operate under normal current, the overload protector fails. Replace; otherwise, the compressor is faulty.
7. It may be because the refrigerant in the freezer is leaking cleanly. First check whether there is any refrigerant running out of the freezer. Generally, the reason for the leakage of fluorine in the freezer is because the compressor of the freezer or the evaporator and the condenser have loopholes, resulting in the leakage of the refrigerant in the freezer. .
8. If there is no problem in the above inspection, it must be caused by the damage of the compressor. It may be that the motor unit of the refrigerator compressor is burned out, the fuse of the compressor is blown, and the motor turns short circuit, and the compressor needs to be replaced.
Among the above reasons, the first three are external factors, and the last five are internal factors. If the freezer compressor is caused by internal factors, the freezer compressor stops and does not refrigerate when it starts, and the business should promptly notify the freezer professional maintenance. Personnel, arrange door-to-door treatment, do not disassemble and replace by yourself, otherwise it may damage the freezer and cause more serious failures.
