I have a 2019 North Trail 22FBS with a furnace issue. The blower comes on but the furnace doesn't kick in. I go outside and hit the re-set and sometimes it starts and sometimes it doesn't . The last time I hit the swith 3x and on the 3rd try it kicked in. It will then usually run for the duration of the camping trip, but at the next site it won't kick in. I had it in the shop and they stopped and started it for 6 hours and it kicked in. I plan on changing out the Sales Switch to see if that will correct the issue. The RV shop took the sales switch apart and cleaned it. Problem in getting a new switch is that they are back-ordered. Anyone out there having the same issue?
