Bounder Furnace Igniter & Board Swap - Our Rolling Rambling's

The full-time RV community is the most generous knowledge-sharing group I’ve ever been part of. Someone has already fixed the exact problem you’re dealing with, documented it in a forum thread, and answered follow-up questions for free. This guide pulls together the best of that collective experience into one place. When your Fleetwood Bounder’s furnace stops igniting — especially on a cold night parked somewhere remote — it stops being an inconvenience and starts being a genuine safety concern, because a failed igniter or a dead control board means no heat, period. I’ve gone through this repair myself, learned which symptoms point to which component, and put together the kind of step-by-step breakdown I wish I’d had the first time I pulled the furnace access panel with cold hands and a flashlight between my teeth. If your furnace is clicking without igniting, running the blower but never firing, or showing error codes you can’t decode, you’re in the right place — let’s get your heat back on.

The Igniter That Actually Survives a Full Season on a Bounder

The igniter electrode is the most common failure point on Fleetwood Bounder furnaces — it burns out, cracks, or loses conductivity and the whole system won’t spark. You can replace the control board and still have a dead furnace if this part is shot.

What works

Ignition fires consistently on first or second call every time after replacement — no hunting or delayed spark.
Wire assembly is pre-assembled and color-coded to match your existing harness, so you’re not wrestling with bare probe crimps in a cramped compartment.
Handles the SF-35, SF-35Q, and SF-42 models across multiple years without fitment surprises — this is the part that actually stays in stock at parts suppliers.

What doesn’t

Aftermarket igniters can take 2–3 weeks to ship, and if you’re already parked in November without heat, you’re calling a mobile tech instead of waiting.
If your control board is also failing (weak spark signal), replacing just the igniter won’t fix the problem — you’ll do this work twice.

I ordered what I thought was the right igniter based on a forum recommendation and didn’t catch the part number mismatch until it arrived — it was designed for a slightly different burner configuration and would have required rewiring the probe position.
