failure
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
4. The screw in the driver board is not tight
EE20 The supply voltage fluctuates too much
1. Compressor runs out of step
2. Wrong program
EE21
3. Impurity inside compressor causes the
unstable rotate speed
1. Voltage signal abnormal
EE22 2. Driver board is damaged
3. Main board failure
1. Main board is damaged
2. Compressor wiring error or poor contact
EE23 or unconnected
3. Liquid accumulation inside
4. Wrong phase connection for compressor
EE24 Ambient Temperature device failure
Compressors U, V, W are just connected to
EE25
one phase or two phases.
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
1. Check the main board or change a new
one
2. Update the correct program
3. Check the refrigeration system
1. Change a new main board
2. Change a new driver board
1. Check the main board or change a new
one
2. Check the compressor wiring
according to the circuit diagram
3. Check the compressor or change a
new one
Change driver board or main board
Check the actual wiring according to the
circuit diagram
