Caution
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
Is the
power supply
voltage between L1 and L2,
L2 and L3, and L1 and L3 within
208 V –10% to 230 V
+10%?
Is the
measured voltage greater or equal
to 220-240 VDC?
Check the inverter power transistor.
Is the power transistor failing?
Is the resistance greater than
the standard?
Measure voltage b and - of
the electrolytic capacitor (C+, C-)
when the compressor is operating.
Calibrate the power voltage.
If L2 and Phase N are disconnected,
replace the distribution box.
Replace the fan motor.
Monitor voltage.
(Instantaneous voltage drop)
Replace the outdoor main PCB
(A1P).
Replace the outdoor main PCB (A1P).
Check the PCB condition.
In case of a serious failure,
compressor failure may lead to PCB
failure. Therefore, failure would recur
when replacing the PCB. To avoid
this situation, recheck whether the
compressor is grounded or whether
the wire is broken. Moreover, check
the compressor after replacing the
PCB.
