EE13
3. Power fluctuations within a short
time
4. Wrong reactor
1. Output abnormity of IPM module
thermal circuit
EE14
2. Fan motor is abnormal or damaged
3. Fan blade is broken
1. Output exception of IPM module
thermal circuit
EE15 2. Fan motor is abnormal or damaged

1. Output exception of PFC module
2. Fan motor is abnormal or damaged
EE16 3. Fan blade is broken
4. Input voltage leap, input power is
abnormal
1. DC motor is damaged
2. For the tri-phase check if the
EE17 neutral is connected

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 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
