First, if you have an ATS (Automatic Transfer Switch) which I suspect you do have, no damage was done by plugging in assuming the ATS was functional.It's job is to only allow ONE source of 120 VAC to the main breaker panel-- either shore or generator.

The generator has two breakers on the generator itself. Turn them off an back ON.

If generator is running (i.e. not out of fuel, etc) exactly what 120 VAC things are working and not working?


The only thing that has trouble running is the a/c. With some fiddling I can get the a/c to run. However, even with the a/c turned off, the generator will start and run for about 10 minutes then it shuts down.

This is unrelated to it being plugged in. It just happens to have a problem at the same time.

Did you check the oil level in the generator? It’s getting an automatic shut down. So, something is causing that.

How much fuel is in the MH? How long has it been since you last used the gen ?

I assumed that you checked the obvious which is the fuel level in the main fuel tank as well as the OIL level in the generator. This may also be an issue with a crack in the rubber incoming fuel line to the generator, which is allowing air to reach the carb instead of just fuel.

Someone plugged in your camper without you knowing about it? Is this in a campground, and maybe someone thought the shore power plug fell out?

Very odd.

Is your genset throwing a code - if so you need to look up what the value means in the manual - you can find that online.

You mentioned triple digit heat - is it possible your genset is in auto shutdown for overheating? The code would tell. Ours used to do that in temps near 100 without air moving over it.

Does anything else work that requires gen or shore power? (Fridge not on LP as example)

And as others have said, there are breakers on your genset itself. Reset those. Also reset the AC breakers on your main panel. This would not explain it shutting down however. Likely causes for that are low oil, fuel issue or overheat. I would bet on the latter since you mentioned the heat already.

And who/how would your RV get plugged back in without you knowing?? Can't say I would ever arbitrarily plug someone's RV back in. Especially with the genset running. Sounds weird or details are missing.

I suspect that the problem was triple digit heat. I went out this morning and the generator started right up. I turned on the a/c and let everything run for a while, with no problems.
Thanks to everyone for your advice, which I did pay heed to and tried.

This was at our home. I have no idea why someone would do this.

one bit of advice

don't wait for the temp to hit 100,
start the genny and then the A/C before it goes over 80
let the genny and A/C ease into the heavy work load by starting early
it was triple digits here Sun, Mon,Tues and 90's Wed
in triple digits, i start early, and i set the 'stat' so the a/c does NOT cycle
it just stays on cold continuously

Good news and thanks for letting us know.

I always found it ironic - and irritating - that when we needed the genset and AC the most was when it the hottest and would shut down due to overheat. I fixed the problem on that RV and sold it but man what a pain. Nothing like being stuck on the beltway in 100 deg heat with no AC.
