Diagnosis Countermeasure
Is
the connector of
thermistor connected
properly ?
Regarding the characteristics of
the thermistor, see the following chart.
Are
the characteristics
of thermistor OK?
*1
NO
NO
YES
*1 Check several times to prove any poor connection
YES
Temperarture thermistor resistance (kΩ)
Temperature-resistance characteristics of indoor heat

Temperature (ºC)
Insert the connector
securely.
Replace thermistor.
(ThI-R)
Replace indoor control.

2. Error detection method
Detection of anomalously low
temperature (resistance)
of ThI-R1, R2, R3.

.
Condition of error displayed
• If -50ºC or lower is
detected for 5 seconds
continuously, compressor
stops. After 3-minutes delay,
the compressor is restarted
automatically, but if this
anomaly occurs again within
60 minutes after the initial
detection.
• Or if 70ºC or higher is
detected for 5 seconds
continuously.
4. Presumable cause
• Anomalous connection
of indoor heat exchanger
temperature thermistor
• Indoor heat exchanger
temperature thermistor
anomaly
• Indoor control PCB anomaly
