Why Maintenance Matters
Your generator is your lifeline during outages—but neglecting proper care can lead to breakdowns when you need power most. Regular maintenance ensures reliability, efficiency, and safety, while skipping it can void warranties and cost thousands in repairs.
The Top 10 Generator Maintenance Mistakes to Avoid
1. Ignoring Regular Service
Skipping scheduled maintenance is the #1 cause of generator failure. Follow your manufacturer’s service intervals for oil changes, filter replacements, and inspections.
2. Using Poor-Quality or Old Fuel
Fuel degrades over time, causing clogs and engine damage. Always use fresh, high-quality fuel and add stabilizers for long-term storage.
3. Improper Fuel Storage
Gasoline and diesel can absorb moisture, leading to contamination. Store fuel in approved containers in a cool, dry place and rotate stock regularly.
4. Never Running the Generator
Letting your generator sit idle for months can cause battery drain and fuel system issues. Run it monthly for 20–30 minutes under load to keep components lubricated.
5. Overlooking Battery Health
Dead or corroded batteries are a common failure point. Clean terminals, check voltage, and replace batteries every 2–3 years.
6. Using the Wrong Extension Cord
Portable generators require heavy-duty, outdoor-rated cords with GFCI protection. Using undersized cords can cause fires or electrocution.
7. Running in Enclosed Spaces
Carbon monoxide kills. Always operate generators outdoors, at least 20–25 feet from doors and windows.
8. Skipping Load Testing
Just because your generator starts doesn’t mean it can handle the load. Perform annual load tests to confirm performance under real conditions.
9. DIY Repairs Without Expertise
Unqualified maintenance can lead to costly mistakes. Hire certified technicians for major servicing and electrical work.
10. Ignoring Warning Lights and Alerts
Modern generators like Generac Guardian and Cummins QuietConnect™ have diagnostic alerts. Don’t ignore them—schedule service immediately.
