Check and save the data of
operating condition.
Check the conditions whether
it occurs immediately after the
power on or during operation
or stopping.
Check the sensed value.
Compare the temperature
on Mente PC with actual
measured value.
Insert the connector
securely
Replace thermistor
(Tho-A).
Replace outdoor control
PCB.
2. Error detection method
Detection of anomalously low
temperature (resistance) of
Tho-A
3.
Condition of error displayed
•
If -30°C or lower is detected for 5 seconds
continuously within 2-minutes to 2-minutes
20-seconds after the compressor ON, the
compressor stops. And after 3-minutes delay,
the compressor starts again automatically, but if
this anomalous temperature is detected 3 times
within 40 minutes after the initial detection.
•
If -30°C or lower is detected for 5 seconds
continuously within 20 seconds after power ON.
4. Presumable cause
• Broken thermistor harness or
the internal wire of sensing
section (Check the molded
section as well)
• Disconnection of thermistor
harness connection
(connector)
• Outdoor control PCB anomaly
