Method of
Malfunction
Detection
Resistance of radiation fin thermistor is detected when the compressor is not operating.
Malfunction
Decision
Conditions
When the resistance value of thermistor becomes a value equivalent to open or short circuited
status.
★
Malfunction is not decided while the unit operation is continued.

P4
" will be displayed by pressing the inspection button.
Supposed
Causes
Defect of radiation fin thermistor
Defect of inverter PCB
Faulty inverter compressor
Faulty fan motor
Troubleshooting
Caution
Be sure to turn off power switch before connect or disconnect connector,
or parts damage may be occurred.
NO
Replace the inverter
PCB.
Measure resistance value of
the radiation fin thermistor.
Is the thermistor
resistance value
normal?
The INV
compressor's
insulation resistance
is not more than
100k
Ω
.
The fan motor's
insulation resistance
is not more than
1M
Ω
.
Does the malfunction
recur when the power
supply turns ON?
YES
YES
NO
YES
YES
NO
NO
Replace the
compressor (M1C).
Replace the fan motor.
Replace the inverter
PCB.
Continue operation.
