Some things will vary depending on how it is installed in each RV but that is a good time to go to real manuals to get an idea of where to go next. Like if it is set next to a wall and I tell you to open that side? Go with what you see, not what we might tell you!!
So I "think" this is the correct manual for that furnace, so give it a hard look to see if it matches:
https://www.dometic.com/assets/14/52...01_81452.pdfit matches.
If correct, down about page 17, I see some good info on how it was installed and that gives a heads up on how to take it apart?
Near page 23, are the electrical drawings and it also shows the sail switch as well as a second item which might need checked as they can go open if overheating.
Do you know about a "limit switch"? It is often just a little button type gizmo which opens if things get too hot. Not a real common problem but it will also keep it from running!
But before doing too much manual labor, do check the troubleshooting section down about page 25 for reset of things.
Hope that gets you going or on the chase!
Maybe this should be turned upside down as the first thing to check may be the last page they list?? Check first, work last!!!
