Furnace works; then doesn't; works again?

I think the board was a bad board, it happens often enough to think that.
If the tech thought that was the problem in the first place and he changed it, then it worked when you tried it, then stopped. I would think the new board is a bad board.
I bought a Dinosaur board for my last rv and was told they make a more reliable board. It might sound silly, but I carry a spare.
It's so easy to plug in a new board and most of the time it solves the problems with furnaces. At least doing that tells me if it in fact is a bad board or not, quick and easy.
The only other thing that comes to mind is the your new wall thermostat. I remember people having issues using the auto mode on digital thermostats where it caused malfunctions between the furnace and fan, igniter, and A/C. You would have to google that cause I don't remember the exact problems with that and I cant find my saved info on it.
