Generator Repair
A strong generator keeps your RV powered during long trips, overnight stays, and unexpected stops. When it fails, the entire trip becomes stressful. We provide complete RV generator repair near you, including in-shop and mobile service, so power issues do not hold you back. Our team works on all major RV and motorhome units and restores stable performance quickly.
We support drivers near Vancouver and Portland with troubleshooting, repairs, replacements, and routine service. If your generator will not start, shuts off under load, loses power inside the RV, or runs unevenly, our technicians diagnose the problem and repair it the right way.

Onan RV Generator Repair and Service
Onan generators power most RVs on the road, which is why model-specific work is important. We service Onan 4000, 5500, MicroQuiet, and Marquis units. Common issues include weak output, uneven running, shutdowns after a few minutes, rough starts, and voltage drops.
We inspect the entire system, including brushes, slip rings, carburettor performance, governor control, coil output, and airflow. Once repairs are completed, we test the generator under load to confirm steady voltage and smooth running for all appliances inside the RV.
Mobile RV Generator Repair
If your generator stops working during a trip, you do not need to tow your RV. We offer mobile RV generator repair near campgrounds, rest stops, driveways, and roadside locations. Our technicians arrive with diagnostic tools, electrical testing equipment, and common replacement parts.
This service helps drivers stuck with no-start problems, shutdowns under load, voltage drops, and loss of power inside the RV. After repairs, we test the generator with your appliance loads so you can continue your trip with confidence.
RV Generator Electrical Repair and Power Diagnostics
Electrical failures are the primary cause of generator problems. When your generator runs but provides no power inside the RV, shuts off when appliances turn on, or delivers unstable voltage, the issue is usually electrical.
We inspect wiring, breakers, sensors, control boards, and the RV transfer switch. Our diagnostics check voltage stability, frequency, and output safety. Once repairs are complete, we test the generator under load to confirm consistent power without drops or surges.
RV Generator Starter and Coil Repair
Weak starters, worn coils, and damaged connections lead to no-start issues, slow cranking, and shutdowns shortly after running. We test ignition output, repair or replace faulty components, and confirm proper starting performance. Before you leave, we verify that it is running stably under normal load.
RV Generator Fuel System Repair
Fuel issues often cause stalling, shutdowns under load, and weak output. We inspect pumps, filters, injectors, and lines for clogs or restricted flow. After cleaning or replacement, the generator receives a steady supply and runs with better stability and efficiency.
RV Generator Carburettor Cleaning
Surging, backfiring, and rough running usually start with a dirty carburettor. We remove buildup, clean jets, adjust the mixture, and replace worn parts when needed. Clean carburetors improve starting, load handling, and quiet running.
RV Generator Maintenance and Tune Ups
Regular service prevents breakdowns on the road. We handle oil changes, filter replacements, spark plug checks, airflow inspections, battery cleaning, and general adjustments. We also service Onan units during routine tune-ups to keep them running cooler, stronger, and more reliably during long trips.

Frequently Asked Questions
Why does my RV generator run but produce no power inside the RV?
This usually relates to the transfer switch, breaker issues, or voltage regulation problems. A full diagnostic test identifies the cause.
Why does my RV generator shut off after a few minutes?
Low oil, restricted fuel flow, overheating, and sensor faults can trigger shutdowns. Testing is needed to confirm the issue.
How often should I service my RV generator?
Oil changes and filter checks should follow usage hours. Regular service prevents failure during long trips.
What causes an RV generator to surge?
Uneven airflow, dirty carburetors, and unbalanced fuel supply cause unstable running and voltage swings.
Why does my generator only run when I hold the start button?
This usually points to a control board or safety circuit issue. Electrical testing is required to fix the problem.
