RV Generator Repair in Washington

An RV generator that won’t start or keeps shutting down strands you without power off-grid. Poulsbo RV diagnoses and repairs onboard RV generators, including Onan and other common brands, on motorhomes, fifth wheels, and travel trailers throughout Washington.

Signs Your RV Generator Needs Repair

Generator faults usually announce themselves at startup or under load:

• The generator cranks but won’t start
• It starts then quits after a few seconds or minutes
• Output power surges, or the voltage is low
• It runs rough, sputters, or won’t take a load like the AC
• Hard starting after sitting unused over the winter
• An error code or repeated fault shutdowns

Why RV Generators Fail

The number one enemy of an RV generator is sitting unused. Modern fuel breaks down in months and gums up the carburetor, which is the most common reason a generator won’t start in spring. Beyond stale fuel, clogged fuel filters, dirty air filters, fouled spark plugs, and weak start batteries all cause hard starting. Generators that aren’t exercised under load also develop carbon buildup. Onan units in particular log fault codes that point directly to the failing system, which speeds up diagnosis.

Our Generator Repair Process

1. We read any stored fault codes and confirm the symptom
2. We test fuel delivery, ignition, and the start battery
3. We provide a written estimate before repair
4. We clean or rebuild the carburetor and replace worn service parts
5. We load-test the generator to confirm it holds output under the AC
6. We verify clean starting and stable voltage

Why Generator Problems Get Worse Over Time

Stale fuel left in a carburetor turns to varnish that gets harder to clean the longer it sits, so a generator that won’t start in spring is cheaper to fix in March than to rebuild in July. Running a generator that surges or runs lean can damage the sensitive electronics in your RV. And a generator only proves itself when you actually need it off-grid, so it’s worth confirming it works before a trip, not during one.

How to Keep Your RV Generator Reliable

• Exercise the generator under load for 30+ minutes monthly
• Use fuel stabilizer or run the carburetor dry before storage
• Change the oil and filter on the recommended schedule
• Replace air and fuel filters periodically
• Keep the start battery charged and healthy
• Address surging or hard starting early before it spreads

Frequently Asked Questions

Why Won't My RV Generator Start After Winter?

Almost always stale fuel that has gummed up the carburetor. We clean or rebuild the carb and service the fuel system to get it running reliably again.

We work on the common onboard RV generators, including Onan and other major brands found in motorhomes and trailers.

It’s likely not making full output under load, often a carburetor, governor, or voltage regulation issue. We load-test to find the cause.

Run it under load for at least half an hour every month. Generators fail far more from sitting than from use.

Yes. Surging or unstable voltage can harm sensitive components, so it’s worth repairing output problems promptly.
