I'm an unhappy, sweaty, middle-aged, suburbanite who can not seem to figure out why I have no power to the roof Air Conditioner. I have one roof air - in front - and it's a newer Atwood uint. Checking for power at the unit I found it was dead. I checked the overhead plug in the rear hallway ceiling - power. Still I checked the breakers. They operate as expected and current is running when on, not when off. So that's good.

My beloved PO had installed an automatic switch that draws power from the cord or Onan as available, but it looks like there's more to it than just that. I shoved my phone in to take some pictures that I'll post to the photo site that show a blue box called Gen-Switch and another blue box called PowerGuard both from Trans-Tech of Plano Texas. I suspect the issues I had with my old air conditioner may have been related to what I'm experiencing now.

A cursory web search brought up little for Trans-Tech of Plano, so I'm hoping someone here might have a memory of what this kind of thing is. Without air conditioning we are not happy campers.

Alternately what would you replace this with? Is there current tech that might be compelling enough to rip it out and upgrade?
