1. RXQ4/5AR, RXMQ6AR: outdoor unit main PCB (A1P)
RXMQ10/12AR: inverter PCB (A3P)
CHECK 4
Refer to page 340.
Replace the PCB.*1
YES
NO
It is supposed that the error results
from external causes other than
failures (e.g. exogenous noises or
thunder).

Caution
Does the power
supply normally come
back on?
Is the
insulation to
ground resistance of the
compressor 100 k
or
more?
The error could have resulted from
external factors other than failures
(e.g. external noise or thunder).
YES
Replace both the compressor (M1C)
and the inverter PCB (A3P).
Replace the inverter PCB (A3P).
