Safety first — read this before working on any generator.
Generators combine three things that hurt people: fuel, electricity, and exhaust. Carbon monoxide from a generator is invisible, odorless, and kills people every storm season. Electrical work on a generator hooked to a house can kill you or kill a lineman working on the grid. The guidance on this site is for general informational purposes — not a substitute for the operator’s manual, common sense, or professional help when you need it.
Carbon monoxide warning
Never run a generator indoors, in an attached garage, in a basement, or anywhere the exhaust can drift into living space. “Cracking a window” is not enough. CO is heavier than air at exhaust temperatures and pools where you can’t see it. Run generators outside, at least 20 feet from any door, window, or vent, with the exhaust pointed away from the house. Install battery-powered CO alarms inside your home. If anyone gets dizzy, nauseated, or has a headache near a running generator, get into fresh air immediately.
Electrical and backfeeding warning
Never connect a generator to your home’s wiring without a proper transfer switch or approved interlock. Plugging a generator into a wall outlet (“backfeeding”) sends power back through your meter onto the grid, where it can kill a utility worker and is illegal in every state. Transfer switches and interlock kits exist for exactly this reason. If you are not comfortable installing one, hire a licensed electrician. There is no safe shortcut here.
General disclaimer
The articles on GeneratorFixIt.com reflect the author’s experience and research at the time of writing. Generators, parts, models, and electrical codes vary. Always disconnect the spark plug before servicing the engine, never bypass a low-oil sensor without understanding what you’re giving up, and follow your generator’s manufacturer manual when it conflicts with anything on this site. If you are not comfortable performing a repair, hire a qualified small-engine technician or, for home standby units, a factory-authorized dealer.
