My electric fan has been used for a long time and has not been cleaned inside. It is covered with a layer of dust. When I turn it on, the electric fan not only does not spin but also makes a buzzing sound.

Before starting repairs, turn off the power first. Use a Torx screwdriver to remove the electric fan housing and find that the motor needs a starting capacitor.

, I turned the motor again by hand and found that the motor rotated very smoothly, which proved to be a problem with the starting capacitor. Now I bought a starting capacitor of the same type online and connected it to the circuit in the original way using electrical tape

Just stick it on and insulate it well. Turn on the electric fan and you will see that it is running normally. Finally, use a dry paper towel or dry towel to clean the dust on the outer cover of the electric fan and the motor inside and install the screws.

There is another situation where you turn the motor by hand and it becomes a little bit stiff or unable to turn. In this case, not only do you need to replace the starting capacitor, but you also need to disassemble the motor. You must do this before disassembling the motor. Use a marker to mark it for easy installation. Check to see if the motor rotor is damaged. If not, remove the coil inside. Use a dry towel to clean the dust inside and the oil on the rotor. Finally, remove the rotor. Apply a little butter on the front and rear ends. This butter is the same as the lubricant used in excavator forklifts.

Finally, just install the motor back in the marked position.

If the rotor or balls are damaged, you need to replace the motor. Just buy a motor of the same model online and install it back into the casing.
