CHECK 11
Refer to page 350.
Make measurement of
resistance of the radiation
fin thermistor.
The
insulation resistance
of the compressor is
less than 100 k
.
NO
YES
YES
NO
Replace the relevant PCB (
1
).
Replace the compressor
(M1C).
Caution
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
The insulation
resistance of the fan motor
is less than 1 M
.
Turn ON the
power supply.
Does the error
recur?
NO
YES
NO
YES
Replace the fan motor.
Replace the relevant PCB (
1
).
Continue operation.
CHECK 11
Is the resistance of the
radiation fin thermistor
normal?
Caution
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
NO
Replace the fan motor.
YES
The insulation
resistance of the fan
motor is
less than 1 M
.
Continue operation.
NO
Replace the relevant PCB
(
2
).
