RV generator repair and service, at your site.

What usually fails

RV generators (Onan is the common brand) fail from disuse more than from use — and Florida gives them both: long humid sits, then hard AC-load work in summer and storm season.

• Fuel system varnish — gasoline sitting in a carburetor through months of storage gums jets and passages. The number-one no-start cause in rigs that summer in Florida.
• Dead or weak batteries — the generator cranks from the house or chassis bank; a bank that sulfated in the heat can't spin it, and the "generator failure" is really a battery failure.
• Control board and starter faults — click-no-crank, crank-no-start, or starts and dies when the button is released.
• Quits under load — runs fine unloaded, dies when the AC compressor kicks: fuel delivery, clogged filters, or an overheating unit with blocked cooling airflow (debris and nests, again).
• Surging and rough running — hunting idle from a partially varnished carburetor or stale fuel, worst right when you need steady power.
• Missed service — oil, filters, and exercise hours nobody tracked; Florida's humidity also corrodes slip rings and connections on units that sit.

Symptoms worth calling about

• Won't crank, cranks without starting, or starts and stalls
• Dies when the AC or microwave loads it
• Surging, hunting, or rough idle
• Fault-code flashes on the start switch (count the blinks — it helps)
• It's storm season and it simply hasn't been tested — that's a service visit, not an emergency, and the right time to have it

What a mobile tech can and can't do on site

On site: fuel system cleaning and carburetor service or replacement, battery testing, starter and control-board diagnosis, filters and oil service, load testing with your actual AC, and exercise/service plans for stored rigs.

Honest limits: internal engine failure (low compression, major mechanical damage) is a replacement or shop conversation. And some no-starts trace back to the RV's fuel tank pickup or lines rather than the generator itself — the diagnosis follows the fuel.

Have this ready when you reach out

• Generator brand and model if you can read it, and its fuel (gas, diesel, propane)
• What it does: nothing, clicks, cranks, starts-then-dies, dies under load
• Any fault-code blink pattern
• When it last ran properly, and whether the rig sat in storage since
• RV year/make/model and where it's parked
