Jayco North Point – Furnace Igniter & Control Board Replacement

Most RV owners let their furnace fail completely before they touch it—and by then, the damage has spread to parts they didn’t know were connected. The Jayco North Point’s heating system is built to a price point, which means Jayco has engineered exactly where corners get cut: the igniter and control board are those corners, sitting at the intersection of heat cycling stress and electrical strain that neither component was designed to handle for a full decade of ownership. I’ve pulled apart enough of these furnaces to see the pattern clearly—a control board weakens from thermal cycling, starts sending erratic voltage to the igniter, and the igniter burns out faster than it should. Then you’re standing in a cold rig at 6 a.m. wondering whether the whole furnace is dead or just one of these two parts. Here’s the mistake: most owners replace one or the other and call it done, only to watch the remaining component fail within a season because it was never the real problem—the whole assembly was already compromised. If you’ve got a clicking furnace, a furnace that lights and dies, or a furnace that won’t light at all, this guide walks you through both repairs so you can stop the cascade before it starts.

When Patchwork Fixes Stop Working: A Complete Unit Swap

Reach a point where you’ve already swapped the igniter and the control board separately, and the heat is still dropping in and out or failing outright, and you’re looking at a deeper truth: neither part was truly the culprit on its own—the furnace as a whole has exhausted its service life. A full furnace replacement is the only answer that actually holds, particularly on earlier-generation North Points running the original Atwood hardware that’s been thermally cycled through too many seasons to stay reliable piecemeal.

What works

• Matches the factory furnace’s footprint and connection layout precisely, so installation involves no custom brackets, no ductwork rework, and no propane line modifications.
• Sidesteps the entire diagnostic rabbit hole; you aren’t testing thermostats and thermocouples and glow plugs across a chain of five components anymore.
• Atwood and Suburban furnaces share core architecture and parts genealogy, which means your spare parts sourcing and technical documentation stay straightforward long-term.

What doesn’t

• You’re making a complete financial commitment instead of investing in a single $40 component, and both the unit cost and labor hours add up quickly.
• Your propane supply line and ductwork connections may show their age during this job—corrosion, brittleness, or separation—and any deterioration means you’re funding extra work beyond the furnace replacement itself.

I almost talked myself into one more igniter replacement in the middle of November, standing in the cold compartment with a multimeter, before admitting the furnace was just too tired to keep patching. Suburban/Atwood RV furnace replacement unit
