Generally speaking, electric fan maybe occur some problems after used for a long time. But what should we do when the fan is “sick”? For the common faults, ceiling fan manufacturers give you some advice and treatment methods, hope to help you.

1. The fan blade doesn’t work; it’s probably out of lube. First of all, we should make sure the fan shaft is lubricated; otherwise the motor cannot drag the blades. If you are at home, first you can turn off the power, and then move the blade by the hand, if blades rotate is not smoothly, basically there is no lubricating oil, you should drip some lubricating oil into the shaft, so as not to affect the motor to drag the blades. So we should pay more attention to the fan maintenance regularly.

2. Wear and tear caused by a long time use. If the fan is used for a long time, the motor will wear out, and the shaft sleeve of the motor will burn up easily. For the blade doesn’t rotate caused by wearing out, the simplest way is to replace parts, especially the shaft sleeve, if wear is easy to burn.

3. Overheating causes the fan doesn’t work. We know there is a motor In the fan, and a overheating circuit breaker into the motor, if short-circuit  occurred in the coil winding, it will make the heat increased for a short time, so that the motor will “strike” do not work.

4. The starting capacitance becomes smaller. When the fan is used for a long time, the capacitance will be reduced, resulting in the motor starting torque become smaller, unable to drive the load. In this case, you can replace it with a new capacitor of the same model. It is recommended to choose a capacitor 20% larger than the original capacitor, which will have better rotation effect

5. Rotating shaft axial clearance is too big. You can remove the motor, and then adjust the gasket. But after install the motor back, you should pay attention to the rotor must be concentric with the bearing, lubricate and slowly tighten, later with a wooden knob knocked on the shaft, to ensure that it is concentric.

6. If it is an electrical fault, you can check the wiring, sometimes its wire damaged, etc., you can repair the problem according to the different status.
