My RV trailer's furnace quit working. I read around and found out that the fan was not coming on and the fan must start before it will turn on the gas and hit the igniters. Fix is a new control board. I found and bought one for about $100 and installed it Which fixed the problem. Being a curious guy and having spend a year in college studying electronics and several more years fixing copy machines I traced the fan motor wire connector to a small relay on the original board., had the number right on top of it. I ordered another relay from an electronics supply for about $12. Little time with a solder sucker and then an iron and replaced it. Then I replaced the new board in the furnace with it and as it works fine, the new board is in a drawer as a back up.
I have no doubt the RV service center would have nailed me for hundreds. If you have done one you could change the board again in a hour max.
