9.2.10 Inverter compressor drive error diagnosis and solution(P4)

Error Code

Malfunction decision

conditions

An abnormal inverter compressor drive is detected by a special

detection circuit, including communication signal detection,

voltage detection, compressor rotation speed signal detection

and so on.

Supposed causes

●

Wiring mistake

●

IPM malfunction

●

Outdoor fan ass’y faulty

●

Compressor malfunction

●

Outdoor PCB faulty

Trouble shooting:

Check the wiring between main PCB
and compressor

Correct the connection or replace

the wires and connectors.

Yes

Check the IPM

Yes

Replace the IPM board or replace

the main PCB

Check the outdoor fan and the

outdoor unit ventilation

Please refer to the solution of

【

Fan

Speed Has Been Out Of Control

】

malfunction

Yes

Check the compressor resistance

values

Replace the compressor.
