I have a Atwood 8335 funace that everything sounds like it is running, but no heat. It fired once, and ran, I heard the iginiton fire on start up. that was the only time i have heard that. Any advise? 2001 Damon Intruder.
Thanks, Chris

I am not trying to insult you at all, but are you sure there is propane in the tank and the valve is open? My Damon has an electric valve to open the propane tank. It got flipped off and I spent a frustrating 30 minutes trying to get the water heater to fire up. Since then I make sure the valve is open and I also turn the stove on to help remove any air in the lines. Even then the WH might take a few on/off flips of the switch to get gas back to the valve there.
Your furnace may be the same way.

Thanks for the input. The gas is on, it accually ran once until I turned down the thermistat. Now it won't refire. I don't hear the igniter go, so i'm not sure what would keep from firing.

Does any one know how to test the board to see if it is working correctly?
Thanks, Chris

I have no idea if your's is like mine, but I had a furnace problem recently and it was found that there was an obstruction in the exhaust pipe which was causing the system to shut down.

Thanks for all your comments. It turned out to be the limit switch. The part was cheap, the replacement took forever. Thanks again, Chris

This just happened to me Fan, no heat. Pull the heater and on top you'll find a panel with screws.Take it off and check the spark gap. Should be 1/8th inch.
