Attention!!
If Check 1, 2 are normal, make sure the following points.
(1) Check Voltage from Filter PCB to Inverter PCB (AC380V between each terminals of LO1, LO2, LO3).
If it does not appear, check the power supply terminal.
(2) Check Voltage from Main PCB to Inverter PCB (DC16.5V between terminals of CN32 (3-4) connector
of Main PCB).
If it does not appear, replace Main PCB.
u If both of above voltages appear, it is considered to be Inverter PCB circuit failure. Replace Inverter PCB and
check operation.
