Thanks many for your input I will be attempting to trace and rectify the challenges to motorhome living. Larry

Started diagnostics by testing LP switch. Have 12 v DC at off position and 13v DC in on position. LP tank is 2/3 full and bleeder valve has LP when opened. Furnaces run and I can hear the lighting module clicking. I reset the T stat and it turns the units on by increasing the temp setting. The previous owner had the front air conditioner replaced. I have yet to check the DIP switch positioning. The furnace breaker is functioning in the bedroom cabinet. The 15 amp fuse is intact. The air conditioners do not produce cold air when turned on. With the written documentation found so far I'm hoping that my challenge lies in the DIP switch on the roof AC unit. Am I missing anything else? Any help would be appreciated. Larry
