Air conditioner generator question

While I have always heard there is no such thing as a dumb question, this may be one. I have a 2014 Palazzo 33.2. While parked and running the front air conditioner with the generator we put something in the microwave. This had never been a problem before, but this time it felt like a breaker tripped and everything went off. After just a brief period of time the microwave would work perfectly but the air conditioner would no longer run off the generator. Is there a separate breaker that controls the air conditioner? Any suggestions as what to look for will be greatly appreciated.

Thanks in advance for any help provided!

    In many cases, there's a 20amp breaker on the genset that only controls the rear ac. Also bypasses the main breaker panel in the coach, when the gen set in running, so the rear air ac breaker in said panel is inoperative.
    Then there are the EMS systems that shed certain loads and usually the ac's when the current draw goes over the main breaker value.
    There may be a set of functional go lights on the panel that are out and usually one of the feeder breakers will reset them and get you going immediately.
    Also, there may be a low voltage protector somewhere that cuts you off when the voltage drops below a certain amount and say, like maybe a 100 volts or so.

    If this is a motor home with mounted generator the A/C may also have a breaker on the generator itself.

    The most common "120 volt device/outlet does not work on generator" issue cause is a tripped breaker ON THE GENERATOR.

    Mine do not have a tripped position other than OFF.
  • The AC circuit breaker will not trip unless the AC unit was drawing too much current. Turning the microwave on will not make the AC draw more current.
    It was probably the circuit breaker on the generator itself that tripped.
  • Yes the Ac unit will have a breaker in your power panel, the panel will have several breakers and 12 volt fuses. Check the breakers to see if one popped.
  • They should be on separate breakers, but only you have the capability to look in your breaker panel and see if this is the case.
