Please help We have a 39Ft Fleetwood Discovery and are problem is we plug into our electric and the refrigerator works fine cools fine the refrigerator is set on AU when we unplug and it should switch to propane it flashes no AC until i manually go and switch to LP and sometimes it takes couple tries for it to lock in Problem is when we are driving the refrigerator does not cool on propane let our house and drove for about 5 hours the refrigerator went from 38degrees to 48 degrees in that period of time. we had it repaired and they put a new element in the unit at a cost of 2,800 dollars only to have the same problem. Our coach is back at the repair shop and they said as of yesterday that can't get it to fail and do what i said we even bought 2 refrigerator fans to circulate the cool air and it didn't work. we are wondering if anyone can help with a solution to this issue. we are contemplating removing and going to a strictly electric refrigerator but don't want to if we don't have to.. Any help will be appreciated
