[Defective fan motor, connector
poor connection, defective PCB]
Is connector connection good?
YES
NO
NO
Is the output of the outdoor unit’s
printed circuit board normal?
Normal
NO
YES

separately.
Rotor lock
[Compressor defect, outdoor
unit circuit defect]
NO
YES
¡
Check compressor wiring visually.
¡
Check insulation resistance. (1 M
Ω
or over)
¡
Check coil wire resistance. (Few
Ω
)
Is output voltage applied to all 3
phases of power transistor?
Inspect compressor.
Defective inverter
If check results are normal,
compressor is locked.
