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...

had the same problem. Turned out to be too much air to the burner which caused the flame to blow out. Does the flame sound rough, roaring a bit? If so, use your fingers to cover the burner air intake a bit at a time until the flame smooths out.
Then a little electrical tape is all thats needed.
Its just like adjusting the air for the water heater, smooth quiet blue flame, no roar or yellow tips.
