If your cooling fan fails to start, maybe the capacitor of the fan has failed. Why does the fan’s capacitance fail? Let us explore together with Suzhou Santian Precision Mould Co., Ltd.
The capacitor is the main part of the fan blade rotation. It can produce a phase difference in the electromagnetic field or a torque in a fixed direction. If there is no capacitor, the fan will not rotate by itself after being energized, but you can push the blade with external force to make it work normally.
1. The capacity of the capacitor is reduced or lost. At this time, the electric fan will not start and run by itself, and it needs to fiddle with the blades to start. Although it can be started after using external force, the speed will be lower than normal speed.
2. The capacitor is short-circuited. In this case, the fan cannot keep rotating. You need to disassemble and check the internal parts of the fan to check the short-circuited parts. After repairing, the fan can be started normally.
The non-rotation of the fan is not necessarily damage to the capacitor. It may also be that the motor or coil of the fan is damaged, which may also cause the fan to not continue to work normally. However, it is not recommended to replace the motor or coil of the fan, because the price of replacement and repair is enough for you to buy a new fan.
