Hello All
I have a micro-minnie Winnebago, 1990. I have gotten everything to work fine (except the generator went bad after running all night in the very cold, but that's another issue). The Atwood furnace was working fine for a couple of years after I bought the rig and cleaned out the mud daubber nests, lubed and rewired as needed. However now the furnace will start blowing but not ignite. I tried it before my wife took off for a short trip and watched the burner ignite. I shut it off and tried it again thinking some by miracle the furnace had fixed itself. This time the flame "popped" and didn't ignite the burner and has not since. Is it the control board and the gas valve? don't know. There's gas to the furnace. I can get a new board but not if unnecessary. Any brilliant ideas? Thanks!!
 
The best place to start figuring out what's wrong with your furnace is here:

Run through that, and if that doesn't get you to the problem, let us know.
