1: Inverter’s Power Transistors Check : Refer to information on P.255~257.
: Refer to information on P.221.
Caution
Be sure to turn off power switch before connecting or disconnecting connector,
otherwise parts may be damaged.
YES
NO
YES
NO
YES
Monitor the voltage
(Instantaneous voltage drop)
YES
NO
When the compressor is running,
measure the voltage b and -
of electrolytic capacitor (C+, C-).
Replace the fan motor
NO
Check the inverter power
transistor. *1
Replace the inverter PC board
assy [A4P (1Ø) or A5P (3Ø)].
Check for the PC board
conditions.
In case of significant failure,
the PC board may have got
faulty due to faulty compressor.
Consequently, even if the PC
board is replaced, it may get
faulty again. To avoid that,
recheck the compressor for
grounding and for any broken
wires. Furthermore, even after
replacing the PC board, carry
out inspections on the
compressor.
Correct the power supply
voltages.
If L2 or Phase N is open,
replace the switch box.
Have the
power supply
voltages between L1 and L2,
L2 and L3, and L1 and L3 fallen within
the range of 380 to 415V±10% (50 Hz) and
between L and N within the range
of 220 to 240V±10%
(50 Hz)?
Is the power
transistor faulty?
Check No.3
Is the resistance above
standard value?
Is the
measured voltage 220
VDC or more?
Replace the inverter PC board
[A4P (1ø) or A5P (3ø)].
Check No.3
