Your backup generator should be there when you need it most. However, like any piece of equipment, it works best when it’s used and maintained regularly. If your generator sits idle most of the time, small issues can develop that may affect its performance during a power outage. Routine generator exercise is one of the easiest ways to keep your system in good working order.At Corbin Electrical Services, Inc., we help homeowners and businesses throughout New Jersey to protect their backup power systems with professional maintenance, repairs, and monitoring services. Here, we discuss how often to run a generator and the benefits of regular generator exercise.Key TakeawaysRegular generator exercise helps improve reliability and extend equipment life.Most standby generators should run an exercise cycle at least once a month.A proper exercise cycle includes an inspection, running the generator under an electrical load, and listening for unusual sounds.Corbin Electrical Services, Inc. has served New Jersey for over 45 years and offers a range of generator models and services.Why Generator Exercise Is ImportantA generator that never runs is more likely to develop problems than one that operates regularly. Routine exercise keeps internal components moving and helps you confirm everything is working as it should.Regular exercise offers several important benefits:Prevent fuel-related problems: Fuel can degrade over time, and components within the fuel system can become clogged or sticky if they aren’t used. Running the generator helps circulate fuel and keep the system operating properly.Reduce moisture buildup: Condensation can develop inside engine components, especially during seasonal temperature changes. Exercising the generator helps evaporate moisture that could otherwise contribute to corrosion.Catch small issues early: Regular use helps you identify small issues before they become major repairs. This includes problems with the oil, filter, fuel, or transfer switch.How Often to Run a GeneratorMost generator manufacturers, such as Generac, recommend exercising a standby generator once a month. Many newer standby units simplify this process by performing automatic exercise cycles on a preset schedule. During these scheduled runs, the generator starts, operates briefly, and shuts down automatically.Portable generators require a different approach. Since they’re not permanently connected to your home’s electrical system, they should only be exercised outdoors in a well-ventilated location and according to the manufacturer’s instructions. Regardless of the type of generator you own, you should always pair exercise with routine maintenance.How to Safely Exercise Your GeneratorBefore starting your generator, take a few minutes to do a basic inspection using this checklist:Air intake and exhaust openings for debrisFuel supply and engine oil levelBattery condition and electrical connectionsVisible signs of leaks or damageOnce everything appears normal, allow the generator to run under a large electrical load. This helps verify that the engine, alternator, and transfer switch can handle a blackout.While the generator is running, watch and listen for unusual engine noises, excessive vibration, surging, warning lights or fault codes, and burning odors or smoke. After each exercise cycle, record the date, run time, and anything you observed. These notes provide valuable information to your technician during professional service visits.What Are Signs You Need Generator Maintenance?Exercise cycles help you spot problems, but they’re not a substitute for professional maintenance. If you notice any of the following, it’s time to schedule a repair:Hard starting or failure to startWarning lights or recurring fault codesFluid leaksExcessive vibrationUnusual noisesPoor performance under loadVisible corrosion or damaged wiringScheduling maintenance before storm season is important.
