Atwood rv furnace only ignites if exhaust port plugged
Hello,
I have a 97 RV with an atwood furnace #8531. Had dang mud dauber in exhaust port. Cleaned with air compressor, a few chunks of dirt came out. Pounded on exhaust pipes.
Still will not ignite on own. I hear the whoosh and clicking a few times. I can smell gas.
Strange thing is if I block the exhaust port. It will ignite and stay working. Felt air warm up. A soon as I uncover the exhaust port the flame will die and air cool back off. I have to plug approx 80% of the exhaust air for it to stay running.
Any suggestions are appreciated.
