1, poor contact of motor circuit.
Sometimes the connecting wire of the motor will be in poor contact, which will lead to poor current transmission and affect the normal work of the fan motor. At this time, it is necessary to check whether the connecting wire of the motor is loose or has poor contact. If so, it should be plugged and unplugged again to ensure tight connection so as to restore the normal operation of the motor.
2. Wear of fan motor parts.
Fan motor consists of many parts, such as rotating shaft, gear, bearing, brush and so on. These parts will wear out after long-term use, thus affecting the normal operation of the motor. At this time, it is necessary to repair or replace parts to ensure the normal operation of the motor.
3. The fan motor has poor heat dissipation.
When the fan motor is running, it will generate some heat. If the heat dissipation of the motor is not good, it will lead to overheating and even damage the motor. At this time, it is necessary to check whether the cooling system of the motor is normal, such as whether the air duct is unobstructed and whether there is dust in the metal shell. Problems can be cleaned up to improve the cooling efficiency of the motor.
4. The motor power supply is insufficient.
Insufficient power supply to the motor will also cause the fan motor to fail to work normally. At this time, it is necessary to check whether the voltage is normal. If the voltage is too low, check whether the power cord is connected correctly or replace the power supply.
In a word, the fan motor of air-cooled refrigerator is out of order, so it should be checked and repaired in time. This can not only restore the normal use of the refrigerator, but also prolong the service life of the refrigerator.
