LG lists the LSXC22426S as a side-by-side refrigerator in its 22 cu. ft. class. On this platform, the IF fault code is one of the more common reasons it gets a service call. 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.
Service calls on this refrigerator most often trace to one of a short list: the IF, dH or CO fault codes. We confirm which one applies against the model and serial number before ordering a part.
