Welcome to the forum its a great place to get your questions answered. This does not sound like a problem with your power supply (shore/generator) I would check the thermostat and the AC contactor/compressor for proper operation. You may need to have a mobile RV tech check things out if this is beyond your DIY level. Let the forum know what you find.

You might try resetting anything that can be reset. I.e., disconnect anything that can be disconnected and re-connected (power cords, battery). Flip the AC circuit breaker open and re-close it. Turn thermostat to off and back on.

Power off - everything (red button) for 10 minutes
Reset all circuit breakers - under stove by floor
Shore power yes and no
Ran generator 10 minutes then tried everything etc…
Reset GFI i knew about
Changed temp request via panel up and down …. W cool selected
I cant find some switch - by the bed in the back ? Maybe I’m looking in the wrong location or any manual controls on the unit in the ceiling
Took off the white panels covering the filters … then the filters ….
Reached up and there was a orange plug - 2 wires …. And NO lights were on
Unplugged this and replugged this … then a green LED came on …
And ac was back ‘online’
Thanks … for suggesting to keep unplugging stuff
The "switch" that is missing (no signal) is likely the one in the utility bay. They are wireless switches and it can lose signal, batteries can die, or it just needs re-paired with the main board. (not really needed as everything it does is accessible on the smart phone app)
