9.2.3 Zero crossing detection error 

When such failure occurs, the main control board must have fault. 

 

9.2.4 Fan speed out of control diagnosis   

 

Is the fan motor connector and 
connection good? 

The unit does not work normally 

Turn off the unit, rotate the cross 
fan.Does it rotate freely? 

No 

Disassemble  the  connection  between 
fan and motor, check if the bearing is 
normal.  If  not,  change  the  bearing.If 
yes, follow the below step. 

Replace the fan motor 

Yes 

Replace the PCB 

No 

Yes

Is the voltage being applied to the fan 
motor? 

Yes 

Shut off the power supply and turn on it 5s later
