No AC power

[Miss Sunshine]

I have no AC power! It’s been very hot and we’ve been running the A/c 24/7. It’s a 2014 sunset 28BH and is plugged into garage 15A outlet. Outlet works fine. All the circuit breakers are on. There is a light on the thermostat which is weird. It must be 12V. What am I missing?

No, the AC is not 12V. It runs on 120V.
How long is the extension cord you are using, and what gauge wire does it have?
Chances are with this heat and humidity, the AC isn't getting enough power.

Oh sorry, I didn’t mean the a/c was 12v, I meant the thermostat. It’s two 30A extension cords, into a 110V adapter. I wonder if that’s fried

If you have 2 30 amp extension cords and then the camper cord that's about 75 ft. You probably melted the 30 - 15 adapter.

15 amp circuit is way short of what you need. Should be at least a 30 amp

[Miss Sunshine]

Guess I’ll be getting a 30A outlet in the garage.

My AC works with 15A circuit.
I had the same problem. Cord plugged in, no power inside RV.
Turned out to be the wires at the plug where your shore cable goes in.
Easy fix, remove the outlet and in the back you might have a broken wire.

There I was only the camper cord and an extension. The connection between the two was fried.
