Service Manual

(4) Start-up failure (following AP1 for outdoor unit control board)
Mainly detect:

Whether the compressor wiring is connected correct?
Is compressor broken?
Is time for compressor stopping enough?

Fault diagnosis process:

Power on the unit

Is stop time of the compressor

longer than 3 minutes?

Restart it up after

3 minutes

Does startup fail?

Are the wires for the compressor connected

correctly? Is connection sequence right?

Connect the wires as

per the connection

diagram

Replace the control panel AP1

If the fault is eliminated?

Replace the

compressor

End
