It was mid-January, and I was parked outside of Flagstaff when the furnace stopped throwing heat. Not gradually—it just quit. I remember the exact moment: standing in the galley, hand on the thermostat dial, and instead of the familiar whoosh of ignition, I got clicking. A rapid, mechanical clicking, like a tiny relay working overtime … Read more

Most RV owners believe their air conditioner either works or it doesn’t—that it’s binary, simple, all-or-nothing. What they don’t realize is that the system can look like it’s running while the cooling half has already given up, and by the time they figure out what’s actually broken, a $30 component failure has cascaded into a … Read more

I’ve got my workbench set up in the bay right now with a Thor Challenger frame spread across it—slideout seal in one hand, a heat gun warming up on the side table, and three inches of gap staring back at me where there shouldn’t be any. This is the kind of thing that doesn’t wait … Read more

Let your Arctic Wolf’s AC capacitor fail and ignore it, and you won’t just lose cold air—you’ll fry the compressor and fan motor running starved and unbalanced until they seize completely. By then, you’re looking at a $1,200–$1,800 unit replacement instead of a $20 part swap. I’ve seen this movie play out dozens of times: … Read more

I’ve got a capacitor sitting on my workbench right now—pulled it from a 2019 Jayco North Point that quit cooling somewhere outside Yuma in late July. The thing’s visibly swollen at the top, the aluminum casing bulging outward in a way that tells you everything you need to know about what happens when 120-volt AC … Read more

“Drew, my Montana’s AC stopped blowing cold last week. The fan spins when I flip the switch, but the compressor won’t engage — I can hear it trying, but nothing happens. What am I looking at?” That’s the text I got from a full-timer in Arizona, and it’s the exact same symptom I’ve debugged a … Read more

I’ve got my head inside a Heartland Eddie Bauer Signature’s furnace compartment right now, and I’m staring at a control board that’s seen better days. The igniter clicked once, then nothing—no spark, no gas valve opening, no heat. I’ve already pulled the igniter (it’s fine), checked the sail switch (working), confirmed the gas valve isn’t … Read more

I had a Grand Design Solitude roll into the yard a couple summers back with an AC unit that wouldn’t kick in — shop quoted the owner $680 just to diagnose and replace the capacitor, plus labor. Sixty bucks for the part itself, nearly seven hundred out the door. That’s when I realized how many … Read more

Most RV owners let their furnace fail completely before they touch it—and by then, the damage has spread to parts they didn’t know were connected. The Jayco North Point’s heating system is built to a price point, which means Jayco has engineered exactly where corners get cut: the igniter and control board are those corners, … Read more

Your Arctic Wolf furnace fired up yesterday, blower engaged, and then went silent—thermostat showing a lockout code you’ve never seen before. So what happened? In nine cases out of ten on this exact model, it’s either the igniter cartridge that’s burned out after a thousand heat cycles, or the control board that’s stopped talking to … Read more
