I believe so, after the initial startup where it runs. I think it is repaired.
I saw a RV repair guy in the resort we are at, I asked him to stop by when he was finished with the one he was working on. He asked what it was doing I told him and he said that's what he is fixing now on the rv where he was at.
He said it is a sail switch. They stick and the stuck switch won't let the gas valve open to fire up. When you move your camper it knocks the switch around and sets it in place until you use it once. Then it sticks again. Exactly our scenario. He said he only had one and he had other calls to make.
I went to the dealer and got a switch, $5. Hour to put in. Sucks tearing these furnaces out, mine was buried under the frig. The dicor seal is tough stuff.
