LT1035CER is LG’s model number for this through-the-wall air conditioner. LG’s own US product page flags this exact model discontinued (read 24 September 2026); it is out of production but not out of the field, and it is exactly the kind of model that has nowhere else to turn for support. On this platform, the CH29 fault code is one of the more common reasons it gets a service call.
Service calls on this air conditioner most often trace to one of a short list: the CH29, CH53 or CH05 fault codes. We confirm which one applies against the model and serial number before ordering a part.
