I turn on furnace at the stat...The furnace fan starts.. then the igniter clicks.. the propane lights. There is flame and heat then after 2 seconds once the ingnighter stops the flame stops but the fan continues to run.This will repeat 2 more times total of three.Then everything turns off.I then see a red flash on the board 2 flashes then a 3 second delay..Then repeats..I can reset the breaker and the entire sequence will repeat..Where to start?Remove the coupler and start cleaning..Then try to replace board?

Check that the flame is in direct contact with the thermocouple.

I am pretty sure I will have to remove a few parts to even see that..

The "flame proving" and the logic board aren't agreeing that it's actually lit. Dirty/Loose contacts on the edge connector to the logic board is a known problem. At least on the water heaters, not sure about the furnace. Clean board edge with pencil eraser and re-tension the connector contacts with a dental pick. Site bryantrv.com has service manuals. Should be able to find one for your Atwood model. Also, post your Atwood model here, you might get more detailed help.

Ok now that I see this I have a good plan in the morning..I have not used the furnace in over a year..I am almost sure I have a nest in there..Plus could use a cleaning I'm sure.. I'm in a high salt air corrosive area..Unplug then replug.. Dab with some cleaner

Not very helpful, since the right side of the image is overlaid with a text box. I can tell from the pic, though, that it uses electronic "flame proving" and not the thermocouple that many of us are familiar with.

What does the book say about the flashing? Its the fail code, so find where it says what it means.

Cleaning and dabbing sounds like a good idea.
