Troubleshooting
∗
Internal wiring errors can cause an input over current. If the equipment stops due to an input over
current after the wires are disconnected and connected again for parts replacement, etc., check for
wiring errors.
Check No.14
Refer to P.122
Check No.13
Refer to P.121
Check No.19
Refer to P.125
Check No.2
Refer to P.120
Re-start the equipment, and
measure the input current.
Check the conductivity of the
electrolytic capacitor of the main
inverter circuit.
YES
YES
Replace the outdoor unit PCB(1).
Replace the outdoor unit PCB(2).
Replace the outdoor unit PCB(2).
Replace the electrolytic capacitor
(1).
It stops
when the current runs
more than the set value for
stopping the input
current.
NO
YES
Is there conductivity?
NO
YES
Are the U, V
and W phases output in good
balance?
NO
NO
(R1063)
Is it normal?
Check No.13
Power transistor output check
Check No.19
Discharge pressure check
Check No.2
Installation condition check
Check No.14
Power transistor check
Caution
Be sure to turn off power switch before connect or disconnect connector,
or parts damage may be occurred.
