Reverse or open phase. Check all 3 phases are present and correct. If correct voltage appears at all three phases, swap any two to cure the fault. Thanks. Helpful?

Error code CH 02. Since this LG model has been discontinued I am looking to repair if possible. Thermistor error but which one and can I just order a new one and simply unplug the old and plug in the new?...

Could not trace your model number or the error code quoted.
On an old machine it would be better to replace all thermistors while you are at it.
The video link will give you an idea of how to go about it.

LG Inverter Air Conditioner showing CH 02 what can I do?


The model number would be on the right hand side of the outdoor unit and same on the indoor unit if it is a midwall split. If it is a flat cassette cieling type you may need to open the grill, which is simply two little levers either side of the grill, and the grill will swing open. Without the model number it is difficult to give accurate info. However, I can offer the following. One, check the condensate drain. You can just blow into the drain pipe from the outside and this sometimes clears clogged mud in the drainpan. Or two, error reading can also come from phase failure (in the case of a three phase unit) or power related problem. This can be solved by switching off the mains and then switching on again to reset. If you have a phase failure you would need an electrician to confirm that the power supply is good. Unless you have a volt meter.
