The electric fan doesn't shake its head because the small shaking motor on the electric fan motor is broken. Just replace this vibration motor. When replacing, please disconnect the power supply to avoid electric shock. The specific operation steps are as follows:

1, grab the electric fan back cover and think about Vala.

2. Remove the motor rear cover.

3. Disconnect the two wires of the vibration motor.

4. Remove the screw that fixes the motor.

5. Install a new shaking motor.

6. Resume installation and experiment, and everything is normal.
