SOURCE: Outdoor model # LSU243HLV Indoor model # LSN243HLV Spli air conditioner looking for error code CH 38
I can not find a 38 anywhere. If I had to guess it would be a temp sensor. Be sure the filter is clean, pull the disconnect out at the outdoor unit for 10 seconds and reinstall. You may find the 38 on the underside of the top panel on the outdoor unit. Best Wishes!!
