AC/generator problem with Pleasureway excel......

It could just be a low idle. The 2800 idle screw is notorious for turning do to vibration.
Check the volts of the gen-set, mine would need adjusting a few times a year.
I liked to use. Kill A Watt meter, I could adjust the idle while looking at the meter. It also allows you to check the Hz.
I always tried to keep mine at 120v Usually the gen-set will surge if the idle is too slow, but below a 103 it will shut down with the A/C running. The Hz should be 60.
Also check the altitude adjustment for you elevation.

Retraite,
I have an Onan Microlite 2800 as I think the op also has due to the fact that it's a model rv similar to mine and also similar vintage. With that said, you got me to thinking about the oil fill level that you state should be up to the oil fill hole(or something like that). So I checked my owner's manual about the correct oil level necessary. The manual says essentially that after the oil is drained from the crankcase, one quart of oil should be added and to check that level with a cleaned dip stick that is inserted back into the fill hole but not screwed in. The proper level is between the "full" and "add" marks. I think if the crankcase was filled to the top of the fill hole it would read way past full wouldn't it?
What part of the manual states that the oil level should be where you've stated? I couldn't find it? Is that true maybe for a 2500 model?

Ernie,

I stand corrected.

For all models - except - the 2800 - one screws the dipstick in all the way to check if the oil is "full". But for the 2800 (and 2500) only, one is to put the dipstick in, but NOT screw it in, to test the "full" mark.

Over the years, I've always just filled it to the bottom of the fill hole - 'cause it's near the same as Onan's way and it's a lot easier - especially when one has crawled under a "B" to check the level.

So, as time passes, by brain "remembered" that the manual said ..., when it was really my interpretation of what I'd read.

Ah well, gettin' old ain't what it's cracked up to be sometimes.

Thanks for getting me to think about it once again.

Ernie is right, it sounds like the generator stalls when the AC tries to restart and can not overcome the head pressure. Common problem on older rigs.

It could also be the oil level in your genny.

The Onan 2800/2500 series requires that the oil level be to the top of the "fill hole"'s bottom edge, and that's a bit above the "full" mark on the genset dipstick. It's in the genset manual, but is sorta hidden in there.

It could also be the capacitor, but checking that oil fill level is easy and no charge.

Cheers.

You need a hard start capacitor from Dometic and not the Supco brand. Had the very same problem with my 2005 Excel.
