10.4  Resetting phenomenon often occurs during operation.   

(That is automatically entering to the status when power is on.) 
The reason is that the instantaneous voltage of main chip is less than 4.5V. Check according to the following 
procedure: 

10.5 Over current protection of the compressor occurs 4 times

 

Resetting phenomenon often occurs during operation .

After changing indoor PCB , check if the failure realease .

Yes

After changing indoor fan motor , check if the failure realease .

Yes

YES

Yes

Power supply circuit has problems .

Indoor PCB is defective.

 

Operation lamp off and Timer lamp flashes

The voltage of power supply is too low  (less than 187V).

No

Indoor PCB is defective.

After changing the main control board , check if the failure realease .

Power supply fault.

No

Outdoor unit fault  (such 

as the compressor).
