Troubleshooting
(*) Check the several connections according to wiring diagram.
V3/W1: Reactor coil resistance value ±0,2 ~ 1 ohm.
V3: Capacitor C4 is correctly connected. GREY cable is connected at the side of the grey stroke
on the capacitor.
W1: Confirm the conditions of F1U & F2U.
Caution
Be sure to turn off power switch before connect or disconnect connector, or parts damage may be
occurred.
Is
the power supply
voltage between 220~240
VAC ±10%?
Check LED on
outdoor unit PC board. (Is the
voltage insufficient?)
NO
When the compressor is running,
measure the voltage between
+ and - of electrolytic capacitor
(C+, C-).
Other factors
Is the wiring correct?
Is the
measured voltage 220
VDC or more?

Field factors
Correct the wiring.
Monitor the voltage
(Instantaneous voltage drop)
* Replace the outdoor PC board
(A1P) ERHQ***V3* / ERLQ***V3*
* Replace the inverter PC board
(A2P) ERHQ***W1* / ERLQ***W1*
