7.6.1-  IPM protection desynchronizing malfunction; compressor overcurrent 

USUAL SYMPTOMS 

- 

Are the control board AP1 and the compressor COMP well connected? Are they loosened? Is the connection sequence correct? 

- 

Is the voltage input in the normal range (test the voltage between L, N of wiring board XT by DC voltage meter? 

- 

Is the coil resistance of compressor normal? Is the compressor coil insulating to copper pipe correctly? 

- 

Is the work load of unit too high? Is the heat of the unit well dissipated? 

- 

Is the refrigerant charged appropriately? 

(AP1 BELOW IS THE CONTROL BOARD OF OUTDOOR UNIT)
