Why Is My Generator Surging?

Why is My Generator Surging?

When you own a generator, you can stay assured of having electricity 24/7. In Wichita, KS, citizens can access the power they need to run their homes. But imagine your generator being out of function when you need it the most. What a bummer!

But fret not. When you know residential electricians who can cater to your needs at the act of a call, you have nothing to worry about. Besides, you can do some research to learn about the reasons causing a surge in your generator.

Knowing the cause might give you the edge of doing something about the generator surge from your end. This is why it is essential to communicate the signs of dysfunction. This blog talks about the various probabilities disrupting the working of a generator. To start with, surging is the most prominent sign!

What is Surging?

Before we move on to learning the causes of a generator surging, let's hop in and know what a surge practically means. In all its true sense, a surge means to suddenly or powerfully move upward or forward. This sudden change can lead to behavioral fluctuations of the object, influencing the surge. 

In terms of generators, surging causes the machine to fluctuate while operating at different intervals. Sometimes, the fluctuations occur randomly, resulting in the reduced efficiency of the generator. 

Various Signs of Surging of Generators

Here are a few common signs of generator surge that electrical contractors, Wichita, KS, deals with. 

  • Sudden fluctuation in the machine's speed
  • Drastic technical changes in various components of the generator
  • Flickering of the machine lights, dimming and getting too bright randomly

Reasons For A Generator Surge

Almost every electrical company, Wichita, KS, has seen so far has had cases of a surging generator to repair. How did they identify the signs? Here are some of the most common reasons for a generator surge. 

Damaged Components

If your generator is facing any problematic component, it can be the reason for its surge. Damaged capacitors are a simple example of generator components ruining the machine's functionality. It can prevent the generator from correctly generating and distributing the power. 

Pilot Jet Clogged

It is pretty common for a generator to surge when idle because of a clogged jet. While the generator is idle, the carburetor is inactive as well instead of performing its usual functionalities. The pilot jet is meant to allow the appropriate amount of gas into the combustion chamber when the throttle butterfly valve is closed.

This is one possible cause of a surging generator. However, getting to an idle jet is pretty easy without removing the carburetor. 

Fuel Problems

Surging is also possible due to fuel problems. Fuel problems are likely due to incorrect fuel, low fuel levels, and bad quality of fuel. Mostly, generators come with fuel requirements. Using fuel outside this requirement can disrupt the parameters leading to operational issues. 

Fuel blockage is another cause of surging generators which is also very much common. You can counter fuel blockages or restrictions by checking the fuel filters and evaluating the quality to ensure the absence of any clogs in the filters. 

Faulty fuel pumps can cause a generator to surge as well. This is why it is essential always to ensure that the fuel pump you are using is in its best condition to operate accordingly. 


Did you know that temperature can be a factor influencing a generator to surge? If you didn't, now you do!

Cold weather can cause a generator to be idle for about 10 minutes or more until the machine warms up again. The gasoline does not vaporize appropriately during the cold, which leads you to leave the unit for a long time until it warms up again and the machine is back in working condition.

Leaving your generator on choke or half-choke causes less air pressure behind the carburetor. This way, it leads to greater conditions of vacuum that sucks up more gasoline in the jets. When the engine starts to warm up, the gas begins to vaporize in the carburetor, letting you move the generator from half-choke mode to open without causing a surge. 

Summing Up

Before you go, it is worth mentioning that all generators aren't perfect to run on their own without proper maintenance. Each of them requires regular maintenance like any other electronic device. Ensure to check the components before any defect reaches its peak position. 

Neglecting the maintenance would incur higher repair costs, or perhaps you may even have to replace the generator!
