Cummins Onan RV Generator Specialists
Cummins Onan is the dominant brand in RV generators, and we have deep expertise in their complete lineup. Common Onan RV repairs include control board replacement, fuel pump and regulator service, exhaust valve adjustment, governor calibration, voltage regulator repair, and complete engine overhaul for high-hour units.
RV Generator Won't Start — Diagnostics
The most common RV generator complaint is a no-start condition. Causes range from simple (dead battery, tripped breaker, fuel valve closed) to complex (control board failure, fuel pump failure, ignition module failure). We systematically diagnose no-start conditions and get your RV generator running reliably.
RV Generator Fuel System Service
RV generators that sit unused for extended periods often develop fuel system problems. Gasoline deteriorates and varnishes carburetor passages, while diesel fuel grows algae and water separates from the fuel. We clean and rebuild carburetors, replace fuel pumps and filters, clean injectors, and treat fuel systems to restore reliable starting and operation.
Mobile RV Generator Service
We understand that bringing your RV to a shop isn't always convenient. Our mobile technicians can service your RV generator at your home, storage facility, or RV park location throughout NYC and NJ. We carry common Onan and Generac RV generator parts on our service vehicles for on-site repair.
