Onan 4000

I just bought a 30' Stealth and took it for the first time this weekend. When attempting to run the A/C and the Microwave, the generator would stop. I called the dealer this morning and said that you cant run both, is this true?

Sounds correct to me. All ya gotta do is shut off the AC while you use the MW.
No biggie IMO.

Welcome to the FR forums!

You are probably right at the power limit. You probably can run the microwave when the compressor on the A/C is off.

My Onan 4000 makes a knocking noise after running for a little bit, but while testing it I put it under load. I turned the AC, microwave, and TV on and it ran all of those at the same time with no problem. I didn't have them all on for a long time but it was well over 1/2 hour. I have a FS2612, but maybe you have a bigger AC?

Also have to ask, was the water heater on electric? Was the fridge on electric? Was any thing else on electric? I think the Onan 4000 is 4000 watts, that is 33.33 amps, full load. (Wattage divided by voltage equals amps).

AC can be 15 amps
Water Heater 10 amps
Refer 5 amps

Note that is 30, close to limit. Television, hair dryer, electric frying pan, even your 12 volt lights cause the converter to draw more current. Don't know where you are, and if running AC, must not have had electric heater on also, but that can be another 10 amps. When camping, one must learn to sacrifice some of the comforts of home in order to appreciate them when they return. Otherwise it would be just like home, and if just like home, why leave in the first place?

some motors may burn up-if not receiving proper working amps
