Atwood Furnace Problems
I have a problem with the Atwood furnace on my 5th wheel (2019 Montana High Country ) I just bought the unit second-hand six months old from a private seller and have never used the furnace system ...

I have a similar problem. My furnace is 17 yrs old. Some surface rust but overall pretty clean.
Fan comes on, a minute or so later gas is turned on and I can hear the igniter.
I can faintly smell propane coming out the furnace exhaust. Faintly. It comes & goes.
Sometimes the furnace will light but then goes out. I can hear a 'woof' or two . . . or multiples.
Sometimes it will run for a few minutes but never reaches a good outlet temp. Maybe 90F. It should be 120F+.
There were muddobber nests inside the flame chamber. They were cleaned out. Otherwise the inside was pretty clean.
The burner was removed and although it looked pretty clean I ran a quick wire brush on it (by hand). I also inserted a rubber coated wire into the gas jet. It went in easily telling me the jet wasn't clogged. I didn't remove the jet for more inspection.
Q1 - Control board, gas valve or rust inside the supply tube (clogging the gas jet)? #1 I don't want to spend $90 for a board I may not need and # 2 it's not exactly easy to disassemble (the supply tube nut is so tight I disassemble the fan shroud to get it out).
Q2 - Can I apply 12V to the gas valve to actuate it? For testing ONLY!
Thanks,
