4 Reasons Why Your Generator Shuts Itself Down

A standby generator is almost a must-have for Santa Cruz, CA homes. When a storm passes through, you won’t need to worry about how you’ll feed and take care of your family. The generator even provides power for your favorite devices and appliances. If the generator won’t stay running and keeps shutting down, you need to know how to get it operating again.

Not Enough Fuel

When the power goes out, a home generator acts as a backup power source. The type of fuel it uses depends on the manufacturer, but common options include diesel, gasoline, propane, and natural gas. One of the more common reasons why it won’t function is that it doesn’t have enough fuel. This is more common among gasoline and diesel models, though, because you need to keep refilling them as they run. Natural gas and propane generators connect to a source that provides an endless stream of fuel.

Electrical Overload

Always pay attention to the load rating, which is what manufacturers use to tell you how much electrical power the generator provides. Though standby generators should produce enough power for your entire home, they may limit some of the things that you can use, such as bigger appliances. The generator will run for a short period and then shut down when it experiences an electrical overload. You can either unplug some things from the generator or opt for a bigger one that can support your favorite items.

Spark Plugs

Just as an engine uses spark plugs, so does your generator. If your generator runs for a few minutes and then shuts down, consider checking the spark plugs. It’s especially important to check if the generator recently had maintenance performed or if you replaced the plugs. There’s always a chance that you picked faulty or damaged ones. It’s also possible that the spark plugs are dirty. Let an electrician decide if cleaning the spark plugs will fix the problem or if you need new ones.

Low Oil

A good maintenance plan for your generator will include checking the oil level and adding more when needed. A low level is just one reason why your generator cannot run as long as it should. The generator needs oil to lubricate the working parts and keep the machine in good shape. Make sure you know what type of oil it uses, though. Adding the wrong mixture or type can seriously damage the generator.

Need Help with Your Generator?

Are you tired of running your generator during storm season and seeing it shut down? Issues with the spark plugs, not having enough fuel or oil, or an electrical overload can keep the generator from running constantly.

Fisher Electric helped us by removing a power wall on our house so we could do some needed siding repair. They came at the scheduled time and following the removal they came at the time we had previously scheduled to reinstall the power wall. Everything went very well and we appreciate the service they gave us

I had a great experience with Fisher Electric and highly recommend them. I needed a 240V plug installed on short notice, and even though I called over the weekend, Jonathon was able to get the job done by Tuesday. They were incredibly easy to schedule, arrived right on time, and offered very fair pricing. Thanks for the excellent service!

Personally, I would give "Fisher Electric" more stars if I could..nowadays it's not easy finding a company with excellent personnel, starting with the owner, Mike and the two electricians who worked with him, Ernesto and Rafael. They were prompt, knowledgeable, professional and personable..Thank you for a great job!! We definitely will recommend you and keep you in our "contacts" for future work!

Mike Fisher and the team at Fisher Electric did an outstanding job on our solar project. From start to finish, they were professional, honest, fast, and very easy to work with. The quality of the installation was excellent, and everything was handled with care and attention to detail. We had 35 solar panels and two batteries installed, and the whole process was smooth and efficient. Mike communicated clearly, followed through on what he promised, and made us feel confident every step of the way. I highly recommend Mike Fisher and Fisher Electric to anyone considering solar or electrical work. Great company, great service, and high-quality work.
