Troubleshooting
Caution
Be sure to turn off power switch before connect or disconnect connector, or parts damage may be
occurred.
Is
instantaneous voltage
drop generated?
Is the
compressor coil
disconnected or is the
insulation
defective?
Turn the main power supply
off, and then disconnect the
connection between the
compressor and inverter.
Continuity check in the
power transistor (IGBT)
Is the continuity
normal?
Is the stop valve open?
Check the
installation conditions.
Check the power
supply voltage.
Is the
inverter
output voltage
generated approximately
at the same increasing speed
for each phase after
turning on again?

) (U-V, V-W,
W-U)
Open the stop valve.
Replace the compressor.
Replace the inverter PC board.
Replace the inverter PC board.
Correct the power supply.
Compressor inspection
Inspect according to the diagnosis
procedure for abnormal noise,
vibration, operating status, etc. of
the compressor.
