Mobile RV Generator Repair and Service
Help with a generator that will not start, stay running or supply power
Tell us how the generator behaves, whether it shows a fault code and when you last used it. We evaluate starting, running and power problems at your RV, along with maintenance needs. Your advisor explains the proposed work, estimate and scheduling.
What we hear from RV owners
Starting, running and power problems
What we service
Get your generator problem diagnosed before replacing parts
Starting trouble, shutdowns and a loss of power output call for different tests. Tell us what happens when you try to use the generator so we can plan the evaluation. Generators we service include Onan (Marquis Gold, MicroQuiet, QG, HDKAJ diesel), Generac, Cummins, and legacy units. Share the model and fuel type so we can confirm the service needed.
Diagnostic & Repair
Won't-start diagnostics, fault-code work, output and voltage testing, AGS troubleshooting, brush and slip-ring service, and component-level repair.
Scheduled Maintenance
Oil and filter service, air filter, spark plugs, fuel filter, valve adjustment, and load-bank testing on the interval your generator's manual specifies.
Season Restart
RV sat all summer? Ethanol-fouled carbs, stale fuel, weak batteries, and dried-out gaskets, we work through the whole list to bring the unit back online.
How the visit works
From diagnosis to an approved repair
Free written service estimate
You tell us the generator make, model, and what it's doing. We quote the visit in writing so you know the number before we schedule.
Diagnosis at your RV
An RV Service Now technician arrives, runs the unit, reads the panel, and identifies the fault or the interval work required.
Repair estimate, then the fix
After diagnosis, we provide a repair estimate covering parts and labor. Your advisor confirms parts availability and timing, and repairs proceed with your approval.
Why this matters here
Include the generator in your travel preparation
Share the generator model, fuel type, hours and service history when you call. We review the symptoms and maintenance needs using the requirements for the installed unit, then provide a written repair or service estimate.
Follow the exercise and service instructions for your generator model, including its ventilation and safety requirements.
Common questions.
Who will actually be working on my RV?
An RV Service Now employee arrives in a company vehicle and works directly with our service team. Tell your advisor about the RV and the work you need so we can match the visit to the right technician. Certificates of insurance are available on request.
My Onan cranks but won't start. Where do you begin?
We check the unit using the procedure for its model, fuel type and symptoms. Battery condition, fuel supply, controls and fault indications help guide the diagnosis before parts are recommended.
Do you carry parts for scheduled service on the truck?
The common maintenance parts (oil, filters, plugs, air filters): yes. Model-specific parts we stage in advance so we finish the work in a single visit.
My generator runs but the air conditioners won't come on. Bad generator or bad transfer switch?
Could be either. We test output voltage and frequency at the generator, then test through the automatic transfer switch. That isolates the fault and avoids replacing the wrong component.
How often should my generator be serviced?
Service intervals depend on the model, operating hours and time in service. We use the manufacturer's schedule for the installed unit and review your maintenance records before recommending work.
Can you fix ethanol damage from fuel that sat all summer?
Yes. Carburetor rebuild or replacement, fuel system flush, and fresh fuel and stabilizer to keep it from happening again. On modern EFI Onans we test the injectors and clean the system.
Should I use non-ethanol fuel or a stabilizer in my generator?
Follow the fuel and storage recommendations for your generator model. Tell your advisor the fuel type and storage history so we can plan the appropriate service.
Can you work on my generator at a campground or storage lot?
Yes. Driveway, storage lot, campground, resort. Wherever the RV is parked. We arrive in a fully stocked service van.
