2. Error detection method
When the suction pipe
temperature thermistor detects
anomalously low temperature
3. Condition of Error displayed
If the temperature thermistor
detects -50°C or lower for 5
seconds continuously within
10 minutes to 10 minutes 20
seconds after compressor ON,
the compressor stops. When
the compressor is restarted
automatically after 3-minutes
delay, if this anomaly ocuurs 3
times within 40 minute.
4. Presumable cause
• Defective suction pipe
temperature thermistor
connection
• Defective suction pipe
temperature thermistor
• Defective outdoor control
PCB
Note:
