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 -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.
4. Presumable cause
• Defective outdoor main PCB
• Broken sensor harness or
temperature sensing section
(Check molding.)
• Disconnected wire connection
(connector)
