I have an LG model LSN306hv duckless split. The AC will not do anything but show CH 24 on the unit in the building. What does CH 24 mean? I tried changing everything on the hand held controller but nothing helps. It still shows CH 24?

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 does the code on the screen mean flashes between ch and 05 ?


CH 5 on these units indicates a communications error between the indoor and outdoor units. Generally, it will require a replacement outdoor board assembly to repair it. Lookup LG parts on the internet or ring them for your nearest Agent or parts. 800 243-0000

LHD65EBL Code CH 01


I had the same problem, and I wound up calling LG's customer support line. The rep I spoke with says that the "CH" code means that the internal thermostat is not able to accurately read the air temperature, and the unit will require servicing.

She gave me a couple of numbers for local folks, and I'll call them in the next day or so, but I'm thinking that this may not be worth the repair, unless it's pretty cheap: I bought the unit for under $100 less than 9 months ago, and I'm not eager to shell out a bunch of money to get it repaired.

Lg split system air conditioner


Try sutting off the power to both units. This may reset the unit. Check out the service manual at LG website www.lgusa.com. Go to their support page and put the model number in. Remove and replace the batteries in the remote. If there is a communication error, the inside unit will display 3 flashes. If all else fails, call LG at 1-800-243-0000. Good Luck!
