I have a 2007 Starcraft Antigua, that had the Dometic fridge recall a couple of years ago. I had the work done, and was nearly 7 months before I used the trailer again. Fridge is fine. My issue...
Like Old Biscuit said, power comes directly from the batt. Campers in those years did not have a main 30A battery fuse like most new campers do. Corrosion can be a factor sometimes, either in connections or in the gear motor itself. We've even seen corrosion on brand new campers' motors. Try testing for power @ the motor first.
