(Defective temperature
sensor input circuit)
2. Error detection method
Detection of anomalously low
temperature (resistance) on
the discharge pipe temperature
sensor
3. Condition of error displayed
When the temperature sensor
detects -10°C or lower for 5
seconds continuously within
10 minutes to 10 minutes 20
seconds after the compressor
ON, the compressor stops. After
3-minute delay, the compressor
starts again automatically, but
if this anomalous temperature
is detected 3 times within 40
minutes.
4. Presumable cause
• Defective outdoor unit main
PCB
• Broken sensor harness or
temperature sensing section
(Check molding.)
• Disconnected wire connection
(connector)
Note:
Discharge pipe
temperature sensor anomaly
