I have a 2015 Georgetown (37.5') which I just purchased three weeks ago. It has two furnaces and they run a few minutes or as long as 20 and then they both quit one at a time about 5 minutes apart. So, we immediately suspected a supply problem. Took it to the dealer and he took off the regulator and tried it on another Georgetown. It worked. The conclusion: moisture in the tank. It even addresses this in the owners manual. At cooler than normal temps, the moisture in the tank (if it's present) freezes as it goes through the regulator. As I noticed, the regulator was covered in a thick layer of frost. We had our first trip planned for Florida, so we took off without a working heater. Guess what, as soon as we hit the warmer temps, both furnaces started working and the regulator no longer froze. Bottom line, dealer is vacuuming the tank and refilling the propane. Given what we know, this should solve the problem. PS - dealer stated that RVs come from FR with a nominal amount of propane just to pressurize the system. The dealer or owners needs to fill it the rest of the way. Our dealer believes it wasn't purged first.

Update: I removed the furnace and went through the entire thing. I started with the high limit switch then moved on to the sail switch. They checked out ok, from there I checked the gas valve and the burner igniter. All good there to, next was a good cleaning of the gas orifice. So after everything I did and checked everything, I benched fired it and it works. Not sure what was wrong, but as long as it works is the important thing. Thanks for all the responses and help

My motorhome has a sf30 furnace and it fires up sometimes OK but other times just blows cold air.
What I've found it the connector on the board has a bad connection if I tap on the plug it sparks up and works fine till its left alone when I'm at work
I'm going to buy a new board and pray that my troubles are over
