Furnace woes in Jayco Swift 15bh 2014

Anyone had trouble with their furnace in this model? Ours starts its lighting sequence but keeps trying to ignite with no luck. Have had it out, checked and repaired once under warranty. However after a year of sitting it is doing the same thing again. Any help appreciated!

There were several discussions last week between owners with the same or similar issues. If you use the search function there should be plenty of information.
Most of the furnaces are the same type. They require a sufficient gas supply, and many owners find webs or critter remains in the exhaust or intake ports which can cause that problem.

Problem solved!

With regards to our furnace issues, a closer inspection revealed the incredibly shoddy steel ground screw on the frame of the trailer had rotted off. This is a trailer that spends its down time under cover. Surely Jayco could go the extra mile and spring for a SS screw, costing .1 of a cent more than the steel one. Also worth spending the time to redo the factory crimps on exposed wire ends and using the heat shrunk variety. Have removed the fuse holder hanging in the middle of nowhere and replaced it with a Blue Seas fuse holder that is part of the battery terminal. Hope this is of help to anyone else with these issues.

Fire up your stove for 30-45 seconds to get the air out of the lines. It will only try to light 3 times before it goes into safe mode. It takes quite a while to get the air out. The furnace does not bleed of the air automatically. I bet this will fix your problem. Same deal with the fridge too.

melblun - concur with all xkuz... says; I too have a 154BH. Another suggestion if I've not recommended it previously: inasmuch as your problem seems intermittent, check for spider web/infestation in or around your propane tubes to the furnace or in that area. Several of us have found that to be a problem. The web can be blown out with compressed air, should any of xkuz..'s advice be ineffective. Let us know.

Thanks for the input. Yes did all that with no results, that's when I started crawling around looking at wiring which I described to "abarkl" above. This is a great site with lots of knowledge and experience to draw on.
