We had a 1999 Soutwind 36Z with galley slide and our ice maker stopped making ice. Our repair person found the tubing in back of the refrigerator where the vent is, was coroded, he replaced the little hose there and it was fixed. I don't know if this is your problem, but that is how our problem was resolved.
My advice is worth what you paid for it!
