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
TH1 ambient temperature probe is damaged
②
Ambient temperature probe socket at main board gets loose
③
Ambient temperature detection port at the main board is damaged
Troubleshooting:
Methods of judging whether ports of master control board are normal:
connect a 20k resistor to the corresponding port to see on the monitor software whether
the discharge temperature or compressor-top temperature is 25°C. If yes, master control
board is normal; if no, replace master control board.
