Furnace wouldn't run... Now it does

I'm with 16ACE27. Not the sail switch. I had the same issue. Replaced with the Dinosaur board and all's well. I didn't see signs of moisture on the board but thinking there was an intermittent board problem.

Wondering how cold it was at your campsite. My previous RV evidently had some water in the propane tank. The regulator would freeze up preventing flow. I would have to get out of bed (brrrr) and pour some warm water over the regulator. would last for a while but then I would have to repeat. Since then I always carry an electric space heater.

Experiencing furnace issues similar to Areveethereyet. My Thor FourWinds was a new left over last fall and recently tried to use the furnace to no avail, luckily I had an electric heater as backup. Fan comes on like normal and burner fires then goes out, this will happen on a repetitive basis. Recently stopped at a wayside that was extremely windy, furnace was into the wind and would not fire at all. As a test turned MH around and bingo furnace worked flawlessly. Immediately thinking negative atmospheric pressure, combustion air adjustment? I’ll have to figure this out solo as there are no local Dometic repair facilities nearby so any input will be greatly appreciated. Thanks Rob
