OCRV Center diagnoses and repairs RV and fleet generators in our Yorba Linda shop, from no-start and surging faults to full overhauls on Onan and Cummins units. Diagnostics start at $285, credited toward an authorized repair.
A generator that will not start or runs rough usually traces back to a handful of likely causes, fuel delivery, a control board, or a worn component. We diagnose at the component level in the shop, then repair the actual fault instead of swapping parts and hoping. All work is in-shop only at our Yorba Linda facility.
Generator work we handle
Generators fail in patterns, so we test along the path the fault points to rather than replacing parts on a hunch. A no-start usually comes down to fuel delivery, ignition, or the control board, while surging often traces to a dirty carburetor or a governor that has drifted out of adjustment. Chino owners bring gas, diesel, and LP units to our Yorba Linda shop for that component-level testing.

Diagnose first, then repair
Every generator job starts with a real diagnostic so we find the cause before quoting parts. The diagnostic fee is credited back against an authorized repair, so the testing is the start of the fix, not wasted money.

- Winding and stator resistance checks
- Slip-ring, brush, and bearing service
- Post-repair run test before pickup
