Forest River Solera – Furnace Igniter & Control Board Replacement

Most RV owners assume their furnace igniter is a sealed, bulletproof component — fire it up fifty times a season and it’ll keep working until the rig is sold. That assumption costs people a lot of cold nights. The truth is more granular: Forest River Solera furnaces fail at the igniter and control board with enough regularity that I’ve stopped being surprised when I pull the access panel and find exactly that problem. You’ll recognize it immediately — repeated clicking from the control board, maybe a faint spark that dies before it reaches the propane, or sometimes just silence after the click cycle ends. The burner never catches. The thermostat sits there demanding heat. And because this particular failure mode shows up consistently enough across the Solera platform, I’ve documented the full replacement sequence here — not as it appears in a service manual, but as it actually plays out when you’re under the cabinet with real tools and real time pressure. Work through this methodically and you’ll have the furnace running without a service call or the dead time that comes with waiting for a dealer appointment. The repair itself is straightforward once you know the exact steps and which parts actually stick around long enough to justify the labor.

Why the Igniter Electrode Burns Out and How to Spot It Early

A Solera furnace that clicks repeatedly without firing is almost always telling you the igniter has lost its ability to generate a reliable spark. The electrode corrodes, the ceramic cracks, or the wire connection loosens — any of these stops the propane from igniting, and the control board keeps trying anyway, cycling through spark attempts until it times out.

What works

• Exact-fit OEM replacement that slots into the existing mounting bracket without modification or transition pieces.
• Connector terminals align with the original harness — no custom crimping or splicing needed in tight spaces.
• Test it immediately after installation; you’ll see spark and flame within seconds if the replacement is seated correctly.

What doesn’t

• Budget-tier igniters with inferior ceramic material break down faster when propane quality is poor or tank sediment is present — you’re back at this repair in two to three seasons.
• Some aftermarket wire jackets become brittle in subfreezing conditions; I’ve seen them crack mid-winter during commissioning, requiring a replacement order and another trip inside the cabinetry.

I once second-guessed whether I had the right electrode after the first light-up looked weak, but that was just the propane regulator needing adjustment — the igniter itself was solid.
