How We Help
EXPERT RV GENERATOR SERVICE IN NORTHERN CALIFORNIA
RV generators are often neglected until they fail — and they tend to fail at the worst possible moments. Regular maintenance dramatically improves reliability and extends the lifespan of your generator. BossBros RV provides complete generator service at your location so you're always ready when you need it.
The most common generator issue we see is a unit that cranks but won't start, or one that starts then stalls. This is typically a fuel delivery problem — a clogged carburetor, stale fuel, or a failed fuel pump. We carry carburetor rebuild kits and fuel system components for Onan, the most common RV generator brand.
We also diagnose and repair generators that run but produce no power or low-quality power. This points to issues with the voltage regulator, AVR board, capacitors, or alternator windings — all of which we can test and repair in the field.
For routine maintenance, we perform complete generator service including oil change, oil filter, air filter, spark plug replacement, and a thorough inspection of all fuel, electrical, and exhaust components. We recommend service every 150 hours or once per year, whichever comes first.
Common Questions
FREQUENTLY ASKED QUESTIONS
My Onan generator cranks but won't start — what's wrong?
This is usually a fuel delivery issue — most commonly a clogged carburetor from sitting with old fuel. We carry Onan carburetor kits and can typically clean or rebuild it on-site for a same-day fix.
My generator runs but won't produce power to the RV — is this fixable?
Yes — this is usually a failed capacitor, AVR (automatic voltage regulator), or a control board issue. We test these components on-site and carry common replacement parts.
How often should I service my RV generator?
Onan and most other manufacturers recommend service every 150 hours or annually, whichever comes first. If the generator sits unused for long periods, we also recommend a fuel system check before relying on it.
Can you service a generator that hasn't been started in years?
Yes — this is a common scenario. Stale fuel, varnished carburetors, and degraded seals are all predictable issues we're well-equipped to address. We'll do a full assessment and give you an honest repair estimate.
