abnormal
1. DC motor is damaged
2. For the tri-phase check if the neutral is
EE17 connected
3. Main board is damaged
4. The fan blade is stuck
EE18 The driver board is damaged
1. PFC module thermal circuit output
abnormal
EE19 2. Fan motor is abnormal or damaged
3. Fan blade is broken

EE20 The supply voltage fluctuates too much
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 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
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
Check whether the voltage is stable
