1. Check if the power is in the normal
range
2. Change driver board
1. Check the compressor
2. Check the waterway system
3. Check if the power is in the normal
range
4. Check if the correct PFC inductor is
used
1. Change a driver board
2. Check if the motor speed is too
low or fan motor damaged, change
another one
3. Change another fan blade
1. Change a driver board
2. Check if the fan motor speed is too
low or fan motor damaged, change
another one
3. Change another fan blade
1. Change a driver board
2. Check if the motor speed is too
low or fan motor damaged, change
another one
3. Change another 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
another one
1. Change a new driver board
2. Check if the motor speed is too
low or fan motor damaged, change
another one
3. Change another fan blade
4. Check if the screw is loose
Check whether the voltage is stable
