RV Generator Repair



Why Choose Blue Moon RV for Generator Service?
Your RV generator is the heart of your electrical system. It's the difference between a climate-controlled cabin and a sweltering afternoon—between a functional mobile office and a dead battery. At Blue Moon RV, we specialize in keeping that heart beating.
As an Authorized Cummins Onan Service and Warranty Center, we provide the highest level of technical expertise in North Texas for both private RV owners and commercial fleet operators.


Many owners don't realize that a struggling generator can damage your inverter, converter, and sensitive onboard electronics. A healthy generator ensures:

Elite Training & Technical Mastery
We don't just "tinker" with engines.
Our technicians undergo a "Vigorous Cycle" of training that far exceeds industry standards: Cummins Factory Certified: Our staff holds the highest level of training offered directly by Cummins.
The Blue Moon Apprenticeship: Before touching a customer's unit, our apprentices complete 200+ hours of hands-on generator specialty training.
The "Scrap-to-Power" Challenge: Every technician has proven their skill by taking a non-functioning scrap generator and rebuilding it into a precision-tuned, working power plant.
Authorized Warranty & New Unit Sales
Searching for a "generator repair shop near me" can be risky—staying within your warranty is vital.
Full Warranty Support: We are a designated Cummins Onan Warranty Center, ensuring your repairs are covered and documented correctly.
New Sales & Installation: Is your old unit beyond its prime?
We sell and install the latest Cummins Onan RV Generators, sized perfectly for your rig's power demands.
Precision Maintenance: Following the Cummins Onan Roadmap
At Blue Moon RV, we don't believe in "generic" service.
A generator is a precision engine that requires specific intervention at exact milestones to maintain its warranty and reliability.
We strictly adhere to the Cummins Onan Manufacturer Service Intervals, ensuring every filter, spark plug, and clearance is checked to factory spec.
Beyond the Oil Change: A "service" at Blue Moon RV is a comprehensive technical overhaul.
We track and execute the specific requirements for every major milestone.
Full oil/filter swap + meticulous inspection for "infant mortality" signs in the engine. Removes metal shavings from the break-in period that can ruin a new engine.
Air filter replacement + fuel system inspection + full load-test calibration. Prevents surging, hard-starting, and power-loss during North Texas summer heat.
Valve Adjustment + Spark Plug replacement + Cooling system flush (for liquid-cooled).
Restores engine timing and prevents "burnt valves" or catastrophic overheating.
Ignoring this milestone is the leading cause of catastrophic generator failure.
Complete brush inspection + slip ring cleaning + belt/hose replacement. Ensures the electrical "head" of the generator can still produce clean, safe power.
We understand that for a commercial medical bus or a full-time RVer, these hours accumulate quickly.
Our team doesn't just check a box; we understand the "why" behind every Cummins requirement.
By following these specific schedules, we help you avoid "part-swapping" repairs later by catching wear-and-tear before it becomes a breakdown.
Whether you're at 50 hours or 1,500, we ensure your power source remains a reliable asset, not a liability.
