When a storm knocks out your power, your generator becomes your backup plan. It can keep the lights on, the food from spoiling, and your heating or cooling systems running. But what happens if you hit the switch and nothing happens? A generator that won’t start can turn an inconvenience into a real problem during extreme temperatures.
The good news is that many common issues have simple fixes. Here’s what to do when your generator won’t start.
1. Check the Fuel Supply
Low or stale fuel is one of the most common reasons a generator won’t start. If your unit runs on gasoline, make sure there’s enough fuel in the tank. Gasoline older than two months can become stale, gumming up components and causing backfire or no ignition at all. Drain old fuel from both the tank and the carburetor before refilling with fresh gas.
2. Top Off the Engine Oil
Generators have a built-in sensor that prevents them from running with low oil levels. Use a dipstick to check the oil, and refill as needed with the type specified by your manufacturer. This is also a good time to consider changing the oil filter to keep your generator in top shape.
3. Inspect the Air Filter
A dirty air filter can prevent airflow to the carburetor, making it difficult for the engine to start. Remove the air filter and, if it looks clogged or dirty, replace it. A clean filter ensures the right air-to-fuel mix for combustion.
4. Test the Battery
Just like your car, if your generator won’t start, it could be due to a dead battery or faulty connections. Test the battery voltage and replace it if it’s not holding a charge. You can also try jump-starting it with your car’s battery. Also, check for any blown fuses, as these can prevent your generator from booting up.
5. Examine the Spark Plug
If your generator still won’t turn over, the spark plug may be dirty. Remove the spark plug and replace it if it’s covered in dirt or debris that can’t be brushed off, or if there are cracks or broken electrodes.
You can also test for a spark by holding the plug against the engine’s crankcase and pulling the generator’s recoil starter. If you see blue sparks, the spark plug is working.
