Fault identification conditions: The resistance value measured under ambient
temperature is abnormal
Take the probe out of the unit, as the reading of the probe may vary significantly under
ambient temperature and actual ambient temperature (the actual reading should be
-25°C~60°C)
Possible causes:
① TH7 temperature probe is damaged
② Defrosting temperature probe socket gets loose
③ Defrosting temperature detection port is damaged
8. THo8 sensor fault
Code displayed: ODU main board displays E015 (applicable to AA/AS/AX models).
Fault detection method: Measure resistance value of ambient temperature probe (At
25°C, resistance value is 50K. The higher the temperature, the lower the resistance value)
Fault identification conditions: The resistance value measured under ambient
temperature is abnormal
Take the probe out of the unit, as the reading of the probe in hot water may be greatly
