It was mid-November in Colorado—the kind of morning where your breath clouds inside the rig before the furnace even kicks on. I’d parked the Sprinter at a high-elevation campground expecting a straightforward weekend, but when I reached for the thermostat dial, I got nothing but a clicking sound from the furnace housing and then a … Read more

You’ll hear two entirely different stories if you call a Keystone dealership versus hunt through RV forums about Arcadia furnace failures. The dealer will tell you the igniter’s burned out and quote you a full replacement. The forum crowd will say it’s always the control board. Here’s the thing: they’re both wrong about it being … Read more

The Friday evening calls never surprise me anymore—a family bundled in blankets at some elevation campground, furnace running but producing nothing but a clicking sound, and a panicked voice on the other end asking if this can wait until Monday. What I’ve learned from working on dozens of Grand Design Reflections is that the furnace … Read more

Keystone Alpine furnaces don’t come with a footnote in the owner’s manual telling you what actually happens when the control board fails—or how to tell the difference between a dead board and a dead igniter without dropping $300 at a service center just to get diagnosed. You’ll find plenty of online chatter about “replacing the … Read more

I was standing outside my Durango one November morning, waiting to hear that familiar *whoosh* of the igniter catching—and instead got nothing but a soft *click*, then silence. The furnace fan would spin up, the blower would push cold air through the vents, but no flame. I’d already ordered a new igniter electrode based on … Read more

Most RV owners assume their furnace will either work or it won’t — that it’s a binary thing, like a light switch. That assumption is dangerously wrong. A Highland Ridge Open Range furnace can fail in ways that look identical on the surface but demand completely different fixes: a dead igniter, a fried control board, … Read more

I’ve got my Crossroads Redwood sitting in a pull-through right now, and I’m looking at the furnace access panel I pulled off the sidewall about an hour ago. Inside that compartment lives two components that almost nobody thinks about until they fail: an igniter and a control board. Those two parts work in tandem, and … Read more

I’ve got a Riverstone control board sitting on my workbench right now — scorched at one corner, the solder joints cracked and discolored where the heating relay used to fire. That blackening tells you everything: a furnace that kept trying to ignite, kept failing, and left the board to absorb the electrical punishment until it … Read more

“Drew, my Cougar’s furnace won’t light at all. I’ve got heat in the morning or it shuts off mid-cycle. Dealer wants $1,400 to even look at it. Am I looking at a full furnace swap, or is this something I can actually fix?” That message came through on a Tuesday afternoon from a guy in … Read more
