on my 2015 Zinger 31SB it has an Atwood furnace. The other day I went to fire it up and it started but then shut off with in a min. I shut things down and I was able to get it to fire but then shut down again. I started looking through the paper work found our camper has a 2 year warranty. I called Atwood they gave me some numbers so I can get it repaired. We have 2 in my area. one comes to the house and the other is a dealer and would need to drop off. I must say Atwood was very nice to deal with. She also told me they have been having problems with this unit. The service guy in my area stopped at the house today and opened it up. He told me there are only 2 things that it can be either igniter, or electrical board. Then he told me what was going on and it come down to the igniter. It would fire up but didn't heat up the element and thinking it wasn't fired up it would shut down after 3 tries of striking. He called Atwood and they again was awesome and parts would be here this Monday or Tuesday. (2nd day shipping). Problem is this unit has to be pulled out no front access panel. Just glad I didn't need it and I caught it before it gets real cold. I shall keep posted on an update.
