Winnebago View – Furnace Igniter & Control Board Replacement

I’m bent over the furnace compartment of a Winnebago View right now, multimeter in hand, tracing the path from the igniter electrode back to the control board mounted in the shadows behind it. The igniter’s corroded—I can see the carbon buildup on the probe tip from here—but that’s not what concerns me. What concerns me is whether that igniter actually failed on its own, or whether the control board’s voltage regulation gave up first and took the igniter down with it. This distinction matters enormously. Replace just the igniter and you’ll miss the real culprit nine times out of ten, which means the furnace quits again in six months, but this time somewhere you can’t get service. I’ve peeled apart enough Views to know that pattern cold. This post walks through the diagnosis that shops miss, the component sequence that actually fails, and how to replace both the igniter and control board together when the situation calls for it—the way it should’ve been done the first time.

Why the Igniter Fails First—But Rarely Alone—on Winnebago View Furnaces

The igniter electrode wears out predictably on View-model furnaces, but igniter-only failure masks a deeper pattern: the control board’s voltage regulation is already compromised, and fixing just the spark plug leaves the actual problem in place. You’ll be back inside this compartment sooner than you think.

What works

• Slides into the SF-Series combustion chamber as a direct fit—the wire harness is factory-assembled, so you’re not wrestling with connector crimps in a confined space.
• Spark becomes reliable and sharp once again; no more hesitation, no more weak clicks—you get the hot arc that burns through carbon deposits clinging to the electrode tip.
• Using the OEM-matched part gives you a clean diagnostic: if the control board is sound, this new igniter will fire without issue, and you’ve confirmed your diagnosis.

What doesn’t

• Inventory on this exact part evaporates from retail channels; a two- or three-week backorder during winter months leaves you sourcing through specialty RV distributors at triple the price if you’re stuck roadside.
• Tackling this swap without a multimeter and confidence reading 12V circuits almost guarantees you’ll scapegoat the new igniter when the control board was the failure source all along—then you’ll be ordering replacements in a loop.

I’ve replaced this igniter on four Views in the last year and caught myself about to order a second one on the third call before I actually measured voltage across the board terminals.
