The ice maker can be a problem..I don't know if I got mine done correctly or not. This a stupid system and if I freeze the solenoid I have no plans to fix it. Don't care if it works or not. Here goes according to the Forest River winterizing guide...Open the low point by the back wheel and drain the line to the ice maker. Cap the line and pull anti-freeze through the system in the normal way...Here comes the tough part: Leave the ice maker on and let it cycle through until the ice cubes come out pink. Mine makes ice at the rate of one small batch per hour. It would take several hours of sitting there watching for pink ice to know if this is done right or not..The alternat method is to drain the system and don't use anti-freeze and let the ice maker cycle until nothing more comes out...I don't know about you but I have no plans to sit around all day waiting for pink ice cubes...Ther must be a better way but I don't know what it is. I'm hoping someone at Whirlpool can tell me how to force the ice maker to cycle more often to flush it out...Haven't found the right person there to ask..YET.
Fixed one problem, going to order unit with gas/electric hot water heater. Guy in campground has Champagne model and hates tankless heater. We don't have sewer hookup and get pumped out weekly, so waiting for water to get hot is not an option. The Champagne guy had his unit winterized today by the dealer. They pulled the refer out, unhooked water line, and jumped the solenoid to cycle it. Didn't see it but will watch next year if we get one. On another note, his wife hates induction cook top. It replaces the range and thus must use microwave convection oven to bake with. They changing the color on the Hathaway editions to a burgundy accent. Not sure whether that will make it look dated in a few years.
