We bought a new 2016 Rockwood 21SS Roo this past March. I wanted to sleep in it in the driveway one night to check things out. The furnace quit in the middle of the night and would not re-light. It was to cold to stay in the camper so I went inside and would look at it in the morning. Had plenty of LP, the fuse were all good and no breakers were tripped. Call my dealer and he said to bring it in and they would look at it right away. They pulled the furnace out and put it on the techs bench and ran some test. The problem was a "High Limit Switch". They had one in stock and replaced it and reinstalled it in the camper and I was out of there in 1.5 hours max! Have not had to use it this summer but have turned it on a number of times to make sure its working!
