WHAT WE SERVICE

RV Generator Repair in Vero Beach, FL

Your RV generator does more than you probably think about. It powers your AC system when you're away from shore power. It keeps your fridge running at rest stops. During Florida's hurricane season, it's your lifeline. And when it fails, everything stops. We service generators on-site across Vero Beach and Indian River County, from basic oil changes to complete rebuilds.

TL;DR

We repair and maintain all RV generators including Cummins Onan, Champion, and Generac models. Mobile service, same-day availability. Oil service starts at $95, fuel system cleaning at $175, starter repair at $200. Call 772-218-5861 to schedule.

Oil & Filter Service

Regular oil changes are the single best thing you can do for your generator's lifespan. We drain the old oil, replace the filter, and refill with the manufacturer-recommended weight. For Onan units, that's usually 10W-30 or 15W-40. We also check the air filter and spark plug while we're at it. Runs $95-175 depending on oil capacity and filter type.

Fuel System Cleaning

Stale fuel is the number one killer of RV generators. If your rig sat for a few months without running, the fuel in the carburetor or injectors has probably turned to varnish. We disassemble and clean the fuel delivery system, replace the fuel filter, and test fuel pump pressure. This is especially common here in Florida where ethanol-blended fuel absorbs moisture and degrades faster. Runs $175-350.

Starter Repair & Replacement

You hit the start button and hear a click, or maybe a slow grinding sound, or nothing at all. Could be the starter motor, the solenoid, corroded wiring, or a weak start battery. We test each component individually. Starter repairs run $200-450. Sometimes it's just a bad connection that takes 15 minutes to fix - we'll always try the simple solution first.

Load Testing & Diagnostics

Your generator starts fine but stumbles when you turn on the AC? That's a load issue. We connect a load bank and test output at various demand levels. This tells us if the generator is producing its rated wattage, if the voltage is stable, and if the frequency stays within spec. Diagnostic testing runs about $89-129 and takes roughly an hour.

Ignition System Service

Spark plugs, ignition coils, and control modules all wear over time. If your generator cranks but won't fire, the ignition system is usually where we look after ruling out fuel delivery. We test spark output, check coil resistance, and verify the control board is sending the right signals. Most ignition repairs fall in the $125-300 range.

Full Generator Rebuild

Sometimes a generator has so many worn components that individual repairs don't make financial sense. A full rebuild includes new bearings, gaskets, valves, ignition components, fuel system overhaul, and a fresh set of brushes on the generator head. We test-run for a minimum of two hours under load after every rebuild. Cost ranges from $500-1,500 depending on the make and model.

WHY YOUR GENERATOR MATTERS IN FLORIDA

Why Generators Are Non-Negotiable for Florida RV Owners

Hurricane Season Backup Power

Florida's Atlantic hurricane season runs June 1 through November 30. That's six months where a major storm could knock out grid power for days or even weeks. If you're staying in your RV during a power outage, your generator is the only thing keeping your AC running, your food cold, and your phone charged. We strongly recommend a full generator service before June 1st every year. It's cheap insurance - an oil change and fuel system check runs about $150-250, and it could keep your family comfortable during a multi-day outage.

Boondocking in the Treasure Coast

Indian River County has some great spots for dry camping - Jonathan Dickinson State Park, the national wildlife refuges, and private land along the Indian River. No hookups means your generator is your power plant. It needs to be reliable. A generator that dies two hours into a weekend trip turns a fun experience into a hot, miserable one. Regular maintenance is the difference. We see generators that run 1,000+ hours without a hiccup because the owners keep up with oil changes and fuel treatment.

The Stale Fuel Problem

This is by far the most common generator issue we fix in Vero Beach. An RV owner parks their rig for the winter, comes back in April, and the generator won't start. Here's what happened: the gasoline in the fuel system absorbed moisture from Florida's humid air, then the ethanol in the fuel separated from the gasoline, creating a layer of corrosive sludge that gummed up the carburetor or injectors. Prevention is simple: add fuel stabilizer every time you fill up, and run the generator under load for 30 minutes at least once a month. If it's already too late, we'll clean it up - but it's cheaper to prevent than to repair.

Overworked During Summer

If you boondock during Florida summers, your generator might run 8-12 hours a day powering the AC. That's hard use. Oil breaks down faster, air filters clog with dust, and mechanical components wear at an accelerated rate. We recommend shortening your oil change interval to every 100 hours during heavy summer use instead of the standard 150. A $95 oil change is a lot cheaper than a $500 electrical component failure caused by a generator that overheated from dirty oil.

OUR PROCESS

How We Service RV Generators

1

Describe the Issue

Call 772-218-5861 and tell us what's going on. Won't start? Runs rough? Shuts off under load? Let us know the generator make and model if you can - it's usually on a label on the unit itself. We'll schedule a visit, typically within 24 hours.

2

On-Site Diagnostic

We arrive at your RV with the tools, meters, and common parts for your generator model. We check oil level and condition, test fuel delivery, inspect the ignition system, and load-test the output. You'll get a clear explanation of what's wrong and a firm price to fix it.

3

Repair, Test, and Verify

After the repair, we run the generator for at least 20 minutes under load. We check voltage stability, frequency, and oil pressure. We don't leave until the generator is running strong and you're satisfied. You pay after everything checks out.

FAQ

RV Generator Repair Questions

How much does RV generator repair cost in Vero Beach?

An oil and filter service runs $95-175. Fuel system cleaning costs $175-350. Starter repair falls between $200-450. A full generator rebuild ranges from $500-1,500 depending on the make, model, and extent of the work needed. We always quote the exact price before we begin.

Why won't my RV generator start?

The most common causes are stale fuel, a dead start battery, a tripped circuit breaker, or a fuel pump failure. If the generator cranks but won't fire, it's usually a fuel delivery or ignition issue. If it doesn't crank at all, check the battery and starter. We diagnose all of these on-site and carry common replacement parts.

How often should I service my RV generator?

Cummins Onan recommends oil and filter changes every 150 hours of operation or once a year, whichever comes first. If you use your generator heavily during Florida's summer months, you might hit 150 hours in a few months. We also recommend running your generator under load for 30 minutes at least once a month, even when you're not using it, to prevent fuel system problems.

Can you work on Onan generators?

Yes. Cummins Onan generators are the most common units we service. We work on the QG 4000, QG 5500, QG 7000, and the larger commercial units. We carry Onan oil filters, spark plugs, air filters, and fuel pump components on our service truck.

Why does my generator keep shutting off after a few minutes?

Usually it's an overheating issue, an overload condition, or low oil pressure triggering the safety shutoff. Check your oil level first. If that's good, the cooling system might be blocked with debris, or you're pulling too many amps. We load-test the generator and check all safety sensors to find the exact cause.

Do I need my generator during a hurricane in Florida?

If you're riding out a storm in your RV, a working generator is a must. Power outages during hurricane season can last days or weeks. Your generator keeps your AC running, your fridge cold, and your devices charged. We recommend a full generator service before June 1st each year, which is the start of Atlantic hurricane season.

What's the difference between exercising and using my generator?

Exercising means running the generator under at least a 50% load for 30 minutes to burn off moisture, circulate oil, and keep fuel from going stale in the carburetor or injectors. Simply turning it on with no load doesn't count. Run your AC or a space heater while the generator runs. This one habit prevents most of the problems we see.

Can you convert my RV generator to run on propane?

In some cases, yes. Dual-fuel conversion kits are available for certain Onan and Champion models. Propane burns cleaner than gasoline, which means less carbon buildup and longer engine life. The conversion runs about $350-600 depending on the generator model. We'll inspect your unit and let you know if it's a good candidate.
