How often should I test-run my generator?

You should test-run your generator monthly for 15-30 minutes under load to ensure it's ready when New Brunswick's next ice storm hits. Regular testing prevents fuel system problems, keeps the engine lubricated, and verifies your transfer switch is working properly.

Monthly Testing Routine
Run your generator for at least 15-30 minutes each month, ideally under 50% load. This means turning on some lights, appliances, or your furnace while it's running. Simply letting it idle without load can actually cause problems called "wet stacking" in diesel generators, where unburned fuel builds up in the exhaust system. For gas generators, no-load running can cause carbon buildup and poor performance when you actually need power.

Seasonal Maintenance Schedule
Beyond monthly testing, perform more thorough maintenance seasonally. Before winter (critical in New Brunswick), change the oil, replace the air filter, and test your fuel system. Check that your transfer switch operates smoothly and all circuits transfer properly. After our harsh Maritime winters, inspect for any moisture damage, corrosion from salt air (especially in coastal areas like Saint John or Moncton), and ensure rodents haven't made nests in the unit.

New Brunswick-Specific Considerations
Given our frequent ice storms and extended power outages, generator reliability is literally a matter of safety. NB Power outages can last days during major weather events. Test your generator before storm season (typically November through March) and keep extra fuel stabilized and ready. If you have a natural gas or propane generator, verify your gas supply and connections are secure - Maritime freeze-thaw cycles can affect fittings.

What to Check During Testing
During each test run, listen for unusual noises, check that the voltage output is stable (should read close to 120V/240V), and verify your automatic transfer switch engages properly if you have one. Watch for any fuel leaks, unusual exhaust smoke, or vibration. Keep a log of your testing - it helps identify developing problems and may be required for warranty coverage.

Professional Maintenance
Have your generator professionally serviced annually by a licensed electrician familiar with backup power systems. They'll check electrical connections, test the transfer switch under TSANB requirements, and ensure your installation remains code-compliant. This is especially important for permanently installed generators that required TSANB permits.
