Duo Therm forced air furnace wont ignite
Hi everyone!
New to this forum and truck camperin' in general (not off to the best start lol)! I have an old 1979 Vangaurd truck camper and one of the( many) issues I am having is that the pilot light in my furnace is working however it wont engage fully and the fan will not spin. I have taken the unit out of the camper and "bench tested" it by checking that there was power going to each wire, and there was, however with the pilot on it wont turn on! I figure that even if the fan doesn't move, at least the unit would ignite normally? only thing I can think of is something messed up with the TH/TR connection. Can I touch the two wires together to bypass the connection to test this safely?
Thanks!
