“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

It was late November, parked at a pull-through in the high desert outside Flagstaff, when I first heard the click-click-click that wouldn’t finish. The igniter would spark, the blower would kick on, but the flame never caught. By the third night, my family was running the engine for heat between campfire sessions, and I was … Read more

Walk into a Newmar dealership’s service bay and ask about a dead AC unit, and they’ll quote you north of $1,200 for diagnosis and parts. Ask the same question on an RV forum, and someone will tell you it’s probably just a $35 capacitor. One of those answers leaves your wallet intact. The dealer isn’t … Read more

Keystone Montana furnaces built between 2010 and 2018 use a Suburban or Atwood heating unit with a control board that sits right where vibration and temperature swings can wear it out faster than you’d expect. I’ve seen them fail at elevation, in cold snaps, and sometimes just from sitting unused for a season. The igniter … Read more

Newmar doesn’t publish a troubleshooting flowchart for furnace failures, and dealer service advisors rarely volunteer that most no-heat situations in a Bay Star Sport come down to two specific, owner-replaceable parts. You won’t find this in the owner’s manual either — what you get is a schematic diagram and a parts list, but no step-by-step … Read more

I was idling in a Costco parking lot outside Tucson when I heard it—a grinding noise from the rooftop AC unit, followed by a thin electrical smell seeping down through the vents. The fan wasn’t dead, but it was struggling hard, moving air like it was pushing through wet blankets. That sound and that smell … Read more
