Someone wrote in and said he had his unit for four years and then it started having this problem and accused it of being a design problem. Well, if it worked fine for four years it's not a design problem. Something has to have happened to make it have problems after that long. After first fixing mine the problem came back. After cleaning the ice out again I pulled it out from the wall and took out the 'duck bill' valve, or rubber nipple, and it was clogged with dog hair. Yes I have two dogs. I cleaned it out and cleaned the fan blades and everything else I could find. Works great now. And it's quieter too. That's from cleaning the fan blades.
