Won't Start After Sitting
Stale fuel gums up the carburetor over a few idle months, so the engine cranks but never catches.
Onan and portable generators, serviced where you park
Our RV generator repair in New Orleans covers the problems that show up at the worst moment: a generator that won't start after sitting all summer, surges when the AC kicks on, or quits halfway through a power outage. We come to your campsite, driveway, or storage lot, test it under real load, and get it running reliably before the next storm.

On the Gulf Coast, the generator isn't just for boondocking. It runs the AC through long outages after a storm, keeps the fridge cold during evacuations, and covers campgrounds when shore power drops. Sitting unused between storms is hard on it too: today's ethanol fuel goes stale in the carburetor, and a generator that hasn't been exercised often won't start when you finally need it.
Stale fuel gums up the carburetor over a few idle months, so the engine cranks but never catches.
A generator that dies after a few seconds often points to low oil, a fuel pump problem, or a bad sensor.
RPMs that rise and fall on their own usually mean a dirty carburetor or a fuel delivery problem.
If it stalls under load, it may be undersized for the AC, out of tune, or not producing full output.
The generator runs but nothing inside works, pointing to a breaker, the transfer switch, or wiring.
Black, white, or blue smoke and rough running mean it needs attention before it causes more damage.
We start by checking oil, fuel, and the hour meter, then try to start it and watch how it behaves. A load test with the AC and other appliances running shows whether it holds voltage and frequency where they should be. From there we clean or rebuild the carburetor, replace filters and plugs, and check the fuel pump, governor, and output breaker. We service Onan, Generac, and common portable generators. Because the generator feeds the coach through the transfer switch, power problems often lead into RV Electrical Repair, and if it stalls only when the rooftop unit kicks on, we check that side too with RV AC Repair. It's all part of our mobile RV repair in New Orleans, from RV parks in New Orleans East to storage lots in Gretna.

The most common cause is stale fuel. Ethanol-blended gas breaks down in a few months and leaves varnish in the carburetor, so the engine cranks but won't run. Running the generator under load for a while each month keeps fuel moving and helps prevent it.
Onan and other manufacturers recommend running it under load for a couple of hours each month. That keeps fuel from going stale, lubricates the engine, and burns off moisture. It's especially worth doing before hurricane season.
Usually, if it's sized for it and running properly. A built-in Onan on most motorhomes is matched to the AC, but a tired or out-of-tune generator may stall when the compressor starts. Call (504) 766-5055 and we'll load test it at your site.
