NO
Is DC15V
detected between
②
and
③
on CNI3?
Is DC15V
detected after disconnecting
outdoor fan motor?
YES
YES
NO
• Model FDC100-140VNX
• Model FDC100-140VSX
Replace immediately the inverter PCB and the power transistor.
Note(1) Under anomalous conditions,
the voltage becomes less than
DC14V.
Note(2) How to check the voltage between
②
and
③
of CNI3?
⑴ ⑵
⑴
Replace inverter PCB
If not solved, replace
Noise filter PCB as well.
Replace outdoor fan motor.
Replace outdoor control PCB
If not solved, replace
inverter PCB as well.
