Hi all, I got called to a ducted LG split unit today thats out on a CH06 fault. I dont deal much with LG.
I reset the controller and powered down the unit but it will not clear the code or attempt start all. Disconnected indoor pipe thermistor, measured 7.5k ohms at aprox 18 deg C. Voltage across sensor plug when connected is 2.7vdc. I have 5vdc from the board. Can anyone advise me of what the voltage out of the board with sensor disconnected should be. When i contacted LG tech support they could not tell me what that voltage should be only that my 2.7vdc with sensor connected is incorrect.
Unit details; Indoor B30AHYN661 Outdoor B30AHYUE61
Thanks.
