If you don't know how to do it yourself, it is recommended to call the manufacturer to find an after-sales solution, because there are several reasons that lead to this problem you mentioned:
1, poor maintenance, long-term lack of lubricating oil.
This is the most common reason why the fan does not rotate, so you can be the first to consider. Fan spindle part is to ensure that there is lubricating oil, otherwise the wind blade on the top of the motive drag can not. If you are at home by yourself, you can choose to turn off the power and then toggle the fan blades, if it spins stiffly, you basically don't have lubricant.
2, wear and tear caused by long use.
If a fan is used for a long time, the motor will wear out, and the motor bushing will burn out easily after wear. And this time the internal resistance of the motor has become larger, with the load capacity becomes lower, the wind blade is easy to rotate. Long-term wear and tear will also make the gap between the shaft and the shaft is too large, so that the wind blade does not turn.
3, overheating caused by the fan does not turn.
In the fan device is a motor, the motor will have an overheating circuit breaker, if the coil winding place a short circuit, will make the heat increase in a short time, so the motor will be "strike" not move. In addition, if the motor is too hot, the load capacity will be correspondingly poor, which causes the power to become low, can not drive the wind blade rotation.
4, electrical problems, such as line damage.
Whatever the use of electrical appliances, should pay attention to maintenance, otherwise the motor slowly aging will affect the use of function.
5, start capacitor capacity becomes small.
When the fan is used for a long time, the capacitance capacity will be reduced, resulting in the motor starting torque becomes smaller, can not drive the load.
If the above can not solve your problem then you can consult a professional cold dryer manufacturer Zhongshan Lingyu Machinery Co.
