AC blowing Generator circut breaker
I have always been able to run the zone 1 AC by itself off the generator many times but now it blows the generator circuit breaker..I can run zone 2 by itself and no problem..what should I be looking at..everything is off except the AC..generator is Onan 6000

Is this correct?

Zone 1 works perfect on shore power? Trips the generator breaker when on the genset?

Zone 2 runs great on shore power or genset?

Nothing has been worked on or changed lately?

Have you tried moving the Zone 1 fan switch to "on"? If you can do this it might help. Do you have any idea how many amps either AC unit is drawing? Do you know if your AC units are 13,500 or 15,000 btu? Do you know if you can run Zone2 with the microwave? It seems like you should be able to do this with a 6K genset.

could be the start capacitor.

When our zone 1 A/C started going out, that was one of the first symptoms ... it would periodically blow the generator circuit breaker. Wasn't long before the compressor completely gave up the ghost and wouldn't cool at all. Have had two of the three original A/C units replaced so far ... just waiting for Zone 3 to quit. :nonono:
