The "BOSS" informed me tonight that our icemaker has stopped making ice. It looks like the fill tube is stopped up with frozen ice. I think the fix is to blow hot air on it with a hair dryer. It is to late to do it tonight but wonder if that is the fix. Also any ides on why it would clog up? Is there some kind of valve that isn't working right? Will attack tomarrow but looking for ideas from folks who have been there and - - - - - .
