RV Generator Service Repair in Florida

Last updated: August 14, 2026

A generator that won't start during a Florida heat wave is not just an inconvenience — if you have family members or pets in the RV, it's a safety situation. We prioritize generator calls for exactly this reason. Most generator failures are predictable and preventable with proper maintenance. But when they do fail, we'll tell you on the phone whether it's a quick fix we can handle same-day or a parts situation that may take longer.

Prices reflect national averages for Florida. Final cost depends on RV type, parts needed, and site location. Call for a free phone estimate — no charge to discuss your situation.

How RV Generators Work and Why They Fail

Most RV generators — Onan (Cummins), Generac, and Westinghouse are the most common — are gasoline or LP-powered units that generate 120V AC power identical to shore power. The generator runs the air conditioner, charges the batteries, and powers 120V appliances when you're not connected to a campground pedestal.

Carburetors are the most common failure point on gasoline generators. RV generators sit unused for months at a time — the gasoline in the carburetor varnishes and clogs the jets. The symptom is a generator that starts and runs for 30-60 seconds before dying, or one that won't start despite cranking. A carburetor cleaning or rebuild solves this in 80% of cases.

Onan generators specifically have a well-documented choke issue — the automatic choke sticks in the closed position, flooding the engine. If your Onan runs for a few seconds and quits, and you can smell fuel, this is the most likely culprit.

Load testing is the only way to know if your generator is producing rated output. A generator that "runs" but is only producing 80% of its rated watts will struggle to start a rooftop AC and may not charge batteries efficiently. We load test every generator after service to verify performance, not just that it runs.

Signs Your RV Generator Needs Service

• Won't start despite cranking — most often fuel delivery (clogged carburetor, stale fuel, failed fuel pump) or a lack of choke function. If you haven't run it in 3+ months, a carburetor cleaning is the first step.
• Starts but shuts off within 30-60 seconds — classic carburetor varnish symptom, or a stuck automatic choke. Run it monthly for 20+ minutes under load to prevent this.
• Runs but AC won't start on generator power — generator isn't producing full voltage or sufficient amperage for the AC compressor. Load test it — if it drops below 108V under 2000W load, it needs service.
• Excessive smoke (blue = oil, white = coolant, black = rich fuel mixture) — each color points to a different internal issue. Blue smoke after sitting for weeks is usually just residual oil in the cylinder burning off — normal. Persistent blue smoke is worn rings or valve seals.
• Generator runs rough or surges — hunting for a stable RPM usually means a dirty carburetor or a governor that needs adjustment.

How We Diagnose and Service RV Generators

We start with output testing: voltage and frequency measurement at the generator outlets. Rated output for most RV generators is 120V AC at 60Hz. Variance beyond ±5% indicates a problem. We then check fuel delivery (fuel pressure and flow), ignition (spark and timing), and air delivery (filter condition, choke operation).

For Onan generators, we check the diagnostic fault codes stored in the controller — Onan Quiet Diesel and Quiet Gasoline series store trouble codes that significantly speed up diagnosis. We carry the Onan service tool and fault code reference for every current Onan model.

Annual maintenance on an LP generator includes new spark plugs, fresh oil and filter, air filter replacement, and a full load test. On gasoline generators, we also drain and replace fuel or add a fuel stabilizer if the unit sits for periods exceeding 30 days between uses — this is the single most effective preventative against carburetor problems.

Generator Use in Florida's Climate

Florida's heat drives more generator use than in any other RV market. A few considerations specific to Florida operation:

• Overheating: Generators have a thermal overload protection that shuts them down if the generator compartment overheats. Florida's ambient temperatures mean the compartment runs hotter than in moderate climates. Ensure the generator compartment vents are clear and unobstructed — debris, insulation that has slipped, or a nearby heat source can trigger shutdowns under normal load.
• Fuel stability: Modern gasoline has a shelf life of about 60 days before ethanol separation begins to affect fuel quality. If your generator sits through Florida's summer rainy season without regular use, the fuel in the bowl varnishes. Run it monthly for 20+ minutes under at least 50% load — run the AC if you have to.
