When the lights go out, your generator becomes the most important piece of equipment in your home. But like any hardworking machine, it needs regular care to stay dependable — especially in Minnesota, where cold weather can take a toll on performance.
Here’s what every homeowner should know about keeping their generator in top shape all year long.
1. Run It Regularly
Your generator shouldn’t sit unused for months. Most models are designed to run a weekly or biweekly test cycle — a short, automatic start that keeps the system ready for real use.
If your generator doesn’t do this automatically, run it manually for 15–20 minutes once a month. This circulates oil, keeps internal parts lubricated, and helps you spot issues before an outage.
Pro tip: Choose a clear, dry day for your test run and make sure the generator’s vents are unobstructed.
2. Check the Oil and Coolant
Just like a car, your generator needs fresh oil to protect its engine. For standby units, check oil at least once every few months (or more often during long outages).
Follow your manufacturer’s schedule for oil changes — typically every 100–200 hours of operation. At the very least, once a year. Use the oil weight recommended for your local climate (cold-weather oil for Minnesota winters).
3. Keep It Clean and Clear
Debris, snow, and ice can block your generator’s air intake and exhaust, causing overheating or shutdown.
Keep a 2–3 foot clearance around the unit and remove leaves, ice, and snow buildup. In the winter, make sure snow drifts don’t block vents or panels.
If you have a portable generator, clean it before storing — and always cover it to protect against dust and moisture.
4. Inspect the Battery
A weak or corroded battery is one of the top reasons standby generators fail to start.
Check the battery terminals for corrosion and ensure the connections are tight. Many homeowners replace the battery every 2–3 years to prevent mid-storm surprises.
5. Schedule Professional Service
Even with good DIY maintenance, your generator should be inspected by a licensed electrician or service technician once a year.
During a professional tune-up, they’ll:
Routine service ensures your generator will perform safely and efficiently when you need it most.
6. Don’t Forget Fuel Storage
If your generator runs on gasoline or propane, make sure you’re storing fuel safely:
