P22 Outdoor Unit Fan Motor Trouble

Error Detection Method

Error Diagnosis

It is judged an error when the outdoor fan motor’s rotating signal cannot be detected normally.

•

1.

2.

Are the connectors “CN-FM_UP” and “CN-FM_LO” firmly 

connected to the outdoor control PC board (lock engaged)?

3

Turn the power on and run the unit again; is P22 triggered 

again? Or can you see or hear anything that is obviously 

wrong in its rotation?
Replace the outdoor control PC board. (If it fails to operate normally even after replacing 

the outdoor control PC board, replace the outdoor fan motor.)
