Troubleshooting
∗
Refer to “Thermistor Resistance / Temperature Characteristics” table on P361.
(V3075)
Caution
Be sure to turn off power switch before connect or disconnect connector,
or parts damage may be occurred.
Is the
resistance
measured after
removing the thermistor
(R6T) from outdoor unit
PC board normal?
(1.8kΩ to
800kΩ)
Replace outdoor unit PC board
(A1P).
Connect the connector and
operate unit again.
NO
NO
Replace thermistor (R6T).
YES
YES
Is
the connector
for liquid pipe
thermistor connected to
X30A on outdoor
unit PC board
(A1P)?
