Code displayed:
ODU main board displays E009 (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
different from the actual reading of water temperature (the actual reading should be
0°C~100°C)
Possible causes:
①
TH2 discharge temperature probe is damaged
②
Discharge temperature probe socket at main board gets loose
③
Discharge 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.
