“Drew, my Ventana’s furnace clicks but won’t catch. I replaced the igniter last year—does that go bad again that fast?” That question landed in my inbox twice in one week, and both times the real culprit wasn’t a dead igniter—it was the control board running weak voltage and burning out a perfectly good new igniter. … Read more

I’ve got the access door open on this Thor Freedom Traveler’s furnace cabinet, and I’m staring at the igniter assembly—a thin ceramic rod sitting inside a metal housing that’s supposed to glow hot enough to light propane, except it isn’t doing either. The thermostat’s been calling for heat for the last three minutes. The blower’s … Read more

A Dometic rooftop AC capacitor on an Entegra Aspire typically runs $40 to $60 online, but a dealership service call to replace it lands you a $180 to $220 labor bill for work that takes less than twenty minutes once you know where to look. When you’re living full-time in your rig, that gap between … Read more

I show up at RV sites to fix things that have stopped working, and there’s a pattern to which jobs pile up on my calendar. It’s not that these rigs leave the factory broken — it’s that certain systems get treated the same way by careless owners, time and time again. Take the furnace in … Read more

I was three weeks into a late-August trip down through Arizona when I noticed the rooftop AC on my Cornerstone wasn’t doing much of anything. The compressor would click on, the refrigerant lines would get cold—I could feel it—but the condenser fan on top just sat there. No spin, no hum, nothing. Within five minutes … Read more

I’ve got my work setup spread across a concrete pad behind bay two at the storage facility where I keep the current rig — socket set hanging on the pegboard, laptop propped on an old toolbox, and a parts catalog open whenever I’m troubleshooting a system that’s gone sideways. Pulled a blackened Suburban igniter electrode … Read more

Skip this repair and your Tiffin Allegro Bus AC won’t just underperform—it’ll trap you in a rig that either won’t cool at all or keeps nuking your breaker every time you fire it up. A weakening capacitor or dragging fan motor is the kind of failure that sneaks up: one week the AC is sluggish … Read more

I’ve got a capacitor sitting on my bench right now—pulled it off a Dutch Star that rolled through last week. The casing is bulged on one side, and if you look at the solder joints where it connects to the fan motor circuit board, they’re cracked and discolored from heat cycling. That’s what a dead … Read more

“Drew, my Allegro Bus furnace clicks three or four times before it finally catches, and half the time it just blows cold air. Is this an igniter thing, or am I looking at something bigger?” I get that question more than I’d expect, and the answer’s usually yes to both. The Tiffin Allegro Bus furnace … Read more

Most Newmar Dutch Star owners don’t realize their furnace’s igniter and control board are on borrowed time until the moment they fail—usually at night, usually in cold weather, usually when the nearest service bay is three hours away. The blower will spin and push air, but no spark, no flame, no heat. I’ve watched owners … Read more
