Applicable Models
ER*Q 011~016*
Method of
Malfunction
Detection
Malfunction is detected according to the temperature detected by subcooling heat exchanger gas pipe
thermistor.
Malfunction
Decision Conditions
When the subcooling heat exchanger gas pipe thermistor is short circuited or open.
Supposed Causes
Faulty subcooling heat exchanger gas pipe thermistor (R4T)
Faulty outdoor unit PC board
Troubleshooting
Refer to “Thermistor Resistance / Temperature Characteristics” table on P251.
(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
(R4T) from outdoor unit PC
board normal?
(3.5 k
Ω
to 360 k
Ω
)
Replace outdoor unit PC board
(A1P).
Connect connector and operate
unit again.
NO
NO
Replace thermistor (R4T).
YES
YES
Is the
connector for
subcooling heat
