YES
NO
Insufficient pressure equalization
Check refrigerant system.
Compressor inspection
Inspect according to the diagnosis
procedure for abnormal noises,
vibration, operating status, etc.
of the compressor.
Compressor overload
Inspection of the compressor
and refrigerant is required.
Approximate value
Detection value
Is
the difference
between high and low
pressure before startup
not more than
0.2MPa?
Is the
secondary current
of the inverter higher than
A (see below) for
each phase?
Turn the main power supply
off, and then disconnect the
connection between the
compressor and inverter.
NO
Replace the inverter PC board.
YES
NO
Replace the inverter PC board.
YES
Is the
inverter
output voltage
generated approximately
at the same increasing
speed on each phase after
turning on again?

(U-V, V-W,
W-U)
*
When operating compressor with
compressor output line disconnected, the
compressor stops due to malfunction after
elapsed time of 5 seconds. Therefore,
check the voltage increase for 5 seconds.
Continuity check in the
power transistor (IGBT)
Is the continuity
normal?
Check No. 10
NO
YES
Open the stop valve.
Is the stop valve open?
Check the installation
conditions.
