Attention!!
If Check 1, 2 are normal, make sure the following points.
Check Voltage from Main PCB to Inverter PCB.
(DC16.0 - 20.0V between terminals of CN126 (1-2) connector of Main PCB).
If it does not appear, replace Main PCB.
If both of above voltages appear, it is considered to be Inverter PCB circuit failure.
Replace Inverter PCB and check operation.
