Jayco Alante – Furnace Igniter & Control Board Replacement

I keep the most common failure components stocked in my van because certain repairs come up so predictably I’d lose time driving to a supplier. When I show up to a rig and already know what’s wrong before I open the access panel — that’s not experience, that’s pattern recognition from seeing the same failure hundreds of times. The Jayco Alante furnace is one of those rigs where the igniter and control board are practically on a replacement schedule — owners hear clicking, smell gas, get nothing, and by the time they call me they’ve already spent two cold nights wondering if it’s safe to run the unit. A furnace that won’t ignite isn’t just uncomfortable — in early spring or late fall camping, it’s a genuine safety and comfort emergency, and guessing at the fix by swapping random parts costs money and time you don’t have. This guide walks you through exactly how I diagnose and replace these components on-site, so you can tell the difference between a failed igniter and a bad control board before you order anything.

The Igniter That Stops the Clicking on Jayco Alante Furnaces

The Suburban 232286 igniter electrode is the crux of the Alante furnace failure pattern — when you hear clicking but get no flame, this is the first part to pull and test, because a weak or corroded igniter will cycle the control board endlessly without actually lighting the gas.

What works

• Igniter glow is immediate and consistent after install — no more waiting for the spark or watching the control board give up after three cycles.
• The electrode sits flush in the mounting bracket without forcing, and the wire harness connects without any rigging or adapter hunting.
• On units where the control board has been cycling but not burning, swapping just the igniter often buys another year or two before the board itself needs replacement.

What doesn’t

• Some aftermarket versions have inconsistent wire gauges — verify the connector actually seats fully before you close up the access panel or you’ll be chasing a no-spark fault you just created.
• If your actual problem is a failed control board (not just igniter degradation), this part won’t fix the clicking; you’ll discover that the hard way after install when the board still cycles the igniter without holding flame.

I’ve swapped this igniter on Alantes where I was certain the control board was the culprit, only to have flame return and stay lit — that moment made me rethink my diagnostics on the next three calls.
