16.4.7 IPM malfunction or IGBT over-strong current protection diagnosis and solution (P0)

Error Code

Malfunction

conditions

When the voltage signal the IPM sends to the compressor drive
chip is abnormal, the display LED shows “P0” and the AC turn
off.

Possible causes

●

Wiring mistake

●

IPM malfunction

●

Faulty outdoor fan assembly

●

Compressor malfunction

●

Faulty outdoor PCB

Trouble shooting:

Check the wiring between main PCB

and compressor. Does an error

exist?

Ensure a proper connection or

replace the wires and connectors

Yes

Check the IPM. Is it in working

order?

Yes

Replace the IPM board or replace

the main PCB

Check the outdoor fan and the

outdoor unit ventilation. Is it in

working order?

Please refer to the solution to the

“fan speed is out of control

”

malfunction

Yes

Check the compressor resistance

values. Are they within acceptable

parameters?

Replace the compressor

Yes

Replace the outdoor main PCB
