Great site! I have an older travel trailer late 60's early 70's. I am remodeling for hunting season. The fridge is about the only thing I am having trouble with still. the coil heats up on both ac and gas but will not cool. I have pulled it out of the unit and turned it up-side down for a couple of days and it will still not cool. no smell coming from it at all. it sat unused for 2 years before i got it. any ideas??? thanks
