1. In many cases, the reason why the fan blades do not turn is due to poor maintenance. If the fan blade is turned by hand after turning off the power, it should be dripped with some lubricating oil into the rotating shaft, so that it can be lubricated, so that it will not affect the motive to drag the fan blade.
2. For the fan blade not rotating due to wear, the easiest way is to replace the parts, especially the shaft sleeve, which is easy to burn off after wear.
3. If the capacitance of the capacitor becomes smaller and the fan does not rotate, you can remove the capacitor and replace it with a new capacitor of the same type. It is recommended to choose a capacitor 20% larger than the original one, which will have a better rotation effect.
4. If the axial clearance of the rotating shaft is too large, you can choose to adjust the gasket after removing the motor. But remember to install the motor back, pay attention to the rotor must be concentric with the bearing, slowly tighten the screw diagonally with lubrication, and finally tap the shaft with a wooden handle to make sure it is concentric.
5. If it is due to an electrical fault, you can check the various lines of the wiring, sometimes the wires are damaged, etc., you can repair the problem.
