Atwood furnace blowing cold some time at night...

I have an Atwood 7900 series furnace in my 2001 Lance 915. DSI iginition, no external timer relay. The past couple nights I have woke up to cold to find the heat has shut off and it just blows cold...

When I heard the ignitor trying to light when it failed, it sounded funky. Not the steady ticking. It went tick tick...........tick. Then reset to ready.

I took the board into the local RV place and they tested it, said it wasn't resetting properly. I'll be ordering a new board from Dinosaur after the holidays.

I also ordered a Wave 3, so I'll be installing that for the winter. The drain on my lone battery was ridiculous with the furnace....
