Good morning from Arizona… and yes, it’s in the hundreds. My rooftop A/C decided to quit in the middle of the night, so I dragged you along while I figured out what was going on and what to do next. I’m a certified RV inspector and tech, but I’ll be honest—I didn’t take the air conditioner class, so this turned into a real-time learning (and sweating) session with my friend Scott from Every Inch RV. First thing I did was stop trusting “it’ll probably be fine” and start testing: I used my amp clamp on the blue wire and watched it pull way too high (12 down to 10 amps when it should’ve been around 7), which explained why my breaker kept popping. Scott also showed a super simple way to isolate the A/C load using a Peacemaker plug-in monitor—plug it in at the A/C outlet and you can see voltage and amp draw without guessing what the rest of the RV is doing. We talked through compressor vs capacitor symptoms (a bad capacitor spikes sky-high at startup; a failing compressor tends to climb and get worse as it runs). Then we got into the real fun: pulling an old Dometic Penguin off the roof, finding rust (yep… water happened at some point), fighting old sealant that was literally pulling roofing material up, and installing the new unit with the right gasket, alignment, and foam/baffle setup so you actually get good delta T. In the end, we had cold air again—and I checked temps to prove it.
