Solution
1. Check the compressor if it works
normally
2. Check the waterway system
3. Check if the power is in the normal range
4. Check if the reactor is used correctly.
1. Check if the motor speed is too low or fan
motor is damaged, replace it by a new one.
2. Replace a new driver board
3. Change the fan blade if it is broken
1. Check the main board or replace the
driver board
2. Check if the motor speed is too low or fan
motor is damaged, replace it by a new one if
any failure.
3. Change the fan blade if it is broken
4. Check the screw on driver board
1.Check the main board or replace the driver
board
2. Check if the motor speed is too low or fan
motor is damaged, replace it by a new one.
3. Change the fan blade
4. Check the input voltage
1. Detect DC motor for mono phase
machine, replace a new one if any failure
2. Check the wiring connection for tri-phase
machine
3. Check the board, replace a new fan motor
driver board or main board if any failure
4. Check if there is any barrier in front of
fan blade and remove it
1. Check if the motor speed is too low or fan
motor is damaged, replace it by a new one.
2. Change a new driver board
