I can operate the microwave which uses 1450 watts, but not the AC. The Airstream dealer service tech got the 28-29 amp figure from Carrier, today.

I guess I'm puzzled that it draws 28 amps at startup but it's on a 20 amp circuit breaker...

Hi, I don't believe in the 28 to 29 Amp start-up figuer. Your trailer has a 30 amp system in it and that would mean that nothing else can work with the air conditioner on. [plugged into 30 Amp system or generator] My generator has run my converter, my refrigerator, my television, and my 11,000 BTU air conditioner all at once. If your batteries are very low, then the converter is going to draw a lot of power; That and your air conditioner might overload your generator. Probably not feasable, but if you could try someone elses generator with your air conditioner, or your generator with someone elses air conditioner, you would be able to tell if you have a generator problem or an air conditioner problem.

If the AC is on a 20A breaker your generator "should" work. The hard start kit is basicly an oversize start-up capacitor. A capacitor is like a battery that stores charge but is able to discharge really quick. So, the way the hard start kit works is the generator quick charges the capacitor and then the capacitor kicks over the compressor on the AC to even out the load.

Bob's right. First need to figure out if the problem is with the AC or the genset.

I bought the 2800 just to avoid these marginal issues. It works great as a home back-up with two refrigerators and a chest freezer. Gotta get on that natural gas/propane conversion... dump the pump

I was at the 2009 Vintage Trailer Jam and it was hot (high 80s) and humid on open house day. My Yamaha 2400 connected to my 2009 International FB with 13,500 BTU system ran 12 hours straight with the AC and no problems. It does seem to struggle for a second or two when the compressor kicks in but then it runs smooth & quiet. We had the fridge on propane but ran the inverter, lights (all replaced with LED), and charger all day along with the AC. Up until that point, I'd never run the AC on the generator for more than 1/2 hour so I was quite pleased that it ran so well for so long without any problems as well.

I live in Lakeside, if you're willing to come out, I'd be happy to run the test that ROBERTSUNRUS suggested, I just purchased a Honda EU3000I Handi generator.
