Solution
1. Change a driver board
2. Check if the fan motor speed is
too low or fan motor damaged,
change it
3. Change the fan blade
1. Change a driver board
2. Check if the motor speed is too
low or fan motor damaged,
change it
3. Change the fan blade
4. Check the input voltage
1. Detect DC motor, replace with a
new one
2. Change a new main board
3. Find out the barrier and work it
out
1. Change a new driver board
2. Check if the fan motor speed is
too low or fan motor damaged,
change it
1. Change a new driver board
2. Check if the motor speed is too
low or fan motor damaged,
change it
3. Change the fan blade
4. Check if the screw is loose
Check whether the voltage is
stable
