Hi everyone. I'm new here and hoping to get some help. I own a 26' Thor Four Winds travel trailer. It is permanently parked being used for a Airbnb rental. It is hooked up to shore power. The furnace and refrigerator both stopped working. I know they require 12v. I don't think they are getting 12v. I do have 12v coming out of the convertor but not at the furnace or refer. I cannot find a reset or a inline fuse. The 12v fuses in the box are good. The trailer has been parked so I doubt a wire came loose. I've checked everything I can think of. They don't work on just the battery alone either. I live near Denali Park Alaska and the nearest RV dealers or service shops are 150 miles away. Anyone had this issue or have any ideas? If someone can solve my problem I will give them a free nights stay in one of my rentals if you ever visit Alaska.
