Lg 1ton inverter ac show CH on display - LG Heating & Cooling

SOURCE: 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.

What is the model of the unit?

SOURCE: "Ch" is displayed on the display

HI!

Appearance of "Ch" on the AC screen is an reminder to clean the AC filter. Whenever it appears you clean the filter and connect the AC to power but, do nut run it is (it should be in switch off mode but, connected to power).

After that press the up and down buttons together on the control panel of the AC (not on the remote) till a beep comes from the AC.

Hi,

Error code = C2 or CH2
Fault = Outdoor temperature sensor open or closed circuit.
Display = Indoor Outdoor.
Indoor Operation = ON

All types of error code solution in this manual.

You need the ohm meter tester to test it.So if you dont have hands on in it.You can call technician.

Please do rate the solution if the issue is resolved or post a comment for further assistance.
