Power factor correction (PFC) fault (a fault of outdoor unit) (AP1 hereinafter

refers to the control board of the outdoor unit)

Mainly detect:

Check if the reactor (L) of the outdoor unit and the PFC capacitor are broken

The failure diagnosis process is as follows:

Start

Check wiring of the
reactor (L) of the
outdoor unit and the
PFC capacitor

Whether there is any

damage or

short-circuit?

Replace it as per the

wiring diagram and
reconnect the wires

If the fault is eliminated?

Remove the PFC capacitor

and measure resistance

between the two terminals.

Is the resistance around zero?

The capacitor is

short circuited and

the capacitor

should be replaced

Restart the unit

If the fault is eliminated?

Disconnect the terminals for the

reactor and measure the resistance

between the two terminals of the

reactor by an ohm gauge

Whether there is any damage

or short-circuit?

Replace the reactor

Restart the unit

If the fault is eliminated?

Replace the control

panel AP1

End
