Malfunction
Error
code
Reason Solution
IPM module temperature
too high protection
EE15
1. Output exception of IPM
module thermal circuit
2. Motor is abnormal or damaged
3. Fan blade is broken
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
PFC module protection EE16
1. Output exception of PFC
module
2. Motor is abnormal or damaged
3. Fan blade is broken
4. Input voltage leap, input power
is abnormal
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
DC fan motor failure EE17
1. DC motor is damaged
2. Main board is damaged
3. The fan blade is stuck
1. Detect DC motor, replace
with a new one
2. Change a new main board
3. Find out the barrier and work
it out
PFC module thermal
circuit is abnormal
EE18 The driver board is damaged
1. Change a new driver board
2. Check if the fan motor speed
is too low or fan motor
damaged, change another one
PFC module high
temperature protection
EE19
1. PFC module thermal circuit
output abnormal
2. Motor is abnormal or damaged
3. Fan blade is broken
4. The screw in the driver board is
not tight
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
Input power failure EE20
The supply voltage fluctuates too
much
Check whether the voltage is
stable
