Found a related youtube video which explained that some Atwood models have a problem with the circuit board sitting flat on a plastic tray. Water can accumulate on the tray causing the circuit board to short out. This kind of made sense to me because I had just towed my trailer home in a major rain storm.
I pulled the cover to the furnace and removed the circuit board sure enough there was water sitting in the tray. I dried out the tray and used canned compressed air to dry the circuit board. I replaced the fuse and turned on the furnace. The fan motor would run and blow cold air but would not light. It would continue to run til I removed the fuse. So, board must be toast.
Apparently Atwood has come up with a retrofit including a new circuit board that mounts the board vertically and according to the youtuber free of charge. We will see about that. Regardless I will try and track down the Retrofit kit.
Anybody had a similar problem?
Yes, that is the problem and the kit fixes that problem. Doug
