My A/C won't start all of a sudden

I spent the past week camped on the beach in Port Aransas with high temps and humidity. I ran the A/C with a MicroAir EasyStart installed 24 hours a day off my Honda 2000 with aux fuel tank. Everything performed flawlessly. But when I got home and hooked up to my 30 amp shore power, the A/C won't start. It acts like it's tripping the breaker, but the breaker isn't tripped. I tried running off the generator again, and same thing. I haven't got a clue where to start trouble shooting. Hoping you good folks have some thoughts...

    I would look for a failed start capacitor.

    That's most likely a bad RUN capacitor, that micro air thingy might have a start cap . Caps fail like crazy in high temps & low current/voltage situations. Run cap is wired between the run & start windings. Once the compressor & fan gets to about 70 to 80 % of working rpm its not needed any longer until unit try's to start again. Compressor probably tripping overload , just a WAG on my part

    How in the world did you get your AC to run of a Honda 2000? Our 12K BTU AC took 2 of them, and then they "screamed" even in eco mode and drank fuel like they were dying of thirst.

    Any chance one of the Micro-Air spade connectors has come loose?

    Did you try turning the breaker off and back on. It is not always visually apparent when a breaker is tripped.
