While we are talking Dometic basement air.............

I have trouble with all three units, however, not the blower motor or compressor motor burn out that most have.

My troubles have all been with the relays on the control board that supply power to the motor or the wiring connections themselves.

My bedroom air was tripping the breaker today. The compressor sounded like it was cutting in and out, and the gauges were acting weird. I opened up the control box and sure enough I found burned wiring connections. Not the ones I had worked a couple of years ago, but new ones.

The point is this, bad wiring connections drop voltage and jack up the current. That's bad for any motor. If you have basement air, I would open up the control boxes and physically inspect for potential damage. Unscrew the wire nuts on the 120V connections and look at them for burning or arcing. It could save you a blower motor or compressor.
