Let a Sunseeker furnace sit dormant through a cold snap with a failed igniter, and you won’t be thinking about the repair cost — you’ll be thinking about how fast hypothermia sets in inside a rig that can’t hold 50 degrees. That’s not hyperbole if you’re parked at elevation in January or anywhere the mercury … Read more

I’ve got the capacitor sitting right here on my bench—cracked housing, one terminal corroded black, the whole plastic shell brittle enough that it crumbles if you press it. This one came out of an Entegra Odyssey that had been baking in Arizona heat for six weeks straight. The owner called me in early August saying … Read more

“Drew, I’ve got a Thor Quantum that won’t light the furnace. It’s clicking, the blower’s running, but there’s no ignition. What am I looking at?” That’s the message I got from a guy selling his rig last month, and it’s almost word-for-word what I hear every fall when the temperature drops and people suddenly remember … Read more

I’m bent over the Entegra’s furnace compartment with my phone’s flashlight wedged against the wall, staring at the igniter electrode. It’s supposed to glow orange when the control board sends 24V across it — that’s the spark that lights the gas. Right now, nothing. No glow, no click, no ignition attempt at all. The owner’s … Read more

A $400 service call to replace a run capacitor on your Entegra Esteem’s rooftop AC unit is what most RV owners end up paying when they finally break down and call a mobile tech. What makes that number sting isn’t just the labor—it’s that the part itself costs twelve bucks, the job takes twenty-five minutes … Read more

Most RV owners treat their furnace igniter like a set-it-and-forget-it component—right up until the moment they actually need heat and nothing happens. The reality on an Entegra Esteem is harsher: the igniter fails quietly, the control board stops responding predictably, and you’re left in the dark (literally) trying to figure out which one killed your … Read more

Your AC fan is running but nothing’s getting cold, or maybe it won’t spin at all — so where exactly do you start diagnosing a Tiffin Wayfarer? The answer, nine times out of ten on this model, points to one of two culprits: either the run capacitor has failed silently or the fan motor is … Read more

I was three weeks into November somewhere near the Utah border when the Wayfarer’s furnace just stopped cooperating. Nights were dropping into the low 30s, and I’d wake up to that telltale clicking — the igniter trying to spark but nothing catching. Before I wasted a service call or started second-guessing myself with dealer parts, … Read more

Walk into any Jayco dealer service department and they’ll tell you a failed AC capacitor means you need a new fan motor—$600 to $800 installed, weeks on the waiting list. Then you hit the RV forums and half the posts say “just swap the capacitor, the motor’s probably fine.” One of those voices is steering … Read more

The Leisure Travel Vans Unity runs a Dometic rooftop AC unit that has a particular weak spot: the run capacitor sits exposed to intense UV and heat cycling, and when it fails—swelling, cracking, or losing its charge—the whole cooling system locks up. You’ll hear the compressor hum, the fan blades won’t move, and if you’re … Read more
