2. Error detection method
Detection of anomalously low
temperature (resistance) on
the discharge pipe temperature
thermistor
3. Condition of Error displayed
When the temperature thermistor
detects -10(-25)°C or lower for
5 seconds continuously within
10 minutes to 10 minutes 20
seconds after the compressor
ON, the compressor stops. After
3-minutes delay, the compressor
starts again automatically, but
if this anomalous temperature
is detected 3 times within 40
minutes.
Note (1) Value in ( ) is for the models
SRC40-60.
4. Presumable cause
• Defective outdoor control
PCB
• Broken thermistor harness or
temperature sensing section
(Check molding.)
• Disconnected wire connection
(connector)
