Anyone else have problems with the Whynter CHC-251S? I think I am on my fourth now, maybe third, they all do the same thing after a couple of years, cooling gets all wacky, and humidity drops low, due to the cooling unit never shutting off. Whynter is recommending I replace the heat sink and the board, to rectify the problem. I can't make heads or tails of what they sent me, as the new heat sink has a single cooling fan, and the new one only has one. Anyone ever replace the electronics in one of these? I was trying to find local service, but that's impossible. I believe this model is discontinued, and it appears the age of the inexpensive wineador are over, as I can't find a unit under $1000 anymore, and even then, very little is in stock. Don't really see why no one can make one of these that lasts...Any help would be greatly appreciated. Thanks!
