It may be that the fan blade is stuck, first turn off the power, open the back cover of the electric fan, wipe the dust on the fan blade clean, and then drip some lubricating oil, the electric fan will rotate.
2. If the motor inside is faulty, the motor will burn out, which will also cause the speed to slow down, so a new motor should be replaced.
3. There may be a problem with the internal rotation of the electric fan, or the wires inside are damaged. If you need to replace the shaft and wire in time, you can ask a professional master to help repair it.
Mainly the fan with oil-containing structure.
