On our walk thru, the service tech impressed on us to carry extra fuses because sometimes fixing a problem on these trailers is as simple as that.
I read the refrigerator trouble shooter guide for my trailer & it says if it fails to work on AC check that the fuse on the AC supply is intact, set to "on", check that thermostat is not set on'0'. If not cold enough it may be because ventilation is inadequate (partial blockage of grills from wire mesh) <-- umm...I did that once.......
ambient temp is too high or the door is not properly closed or the magnetic sealingstrip is defective.
Most importantly, because it is an absorption refrigerator system, if the refrigerator is operated when it is not level and the vehicle is not.moving, liquod ammonia will accumulate in sections of the evaporator tubing. This will slow the circulation of hydrogen and ammonia gas or in severe caes, block it, resulting in a loss ofcooling. Level the vehicle when stopping for more than an hour, otherwise the cooling unit could be permanently damaged due to overheating if left "on".if the vehicle is moving, leveling is not critical as the rolling and pitching motion will pass to either side of level, keeping the liquid ammonia from accumulating in the evaporator tubing.
