One issue my audience always complains about their generator is as a result of it surging, and trust me it can’t be immensely frustrating in a way that you would want to abandon the generator or fix it instantly.

In my previous article, I’ve listed some of the causes of generator surging and now in this article, I will be explaining more about how you can fix a surging generator in a few minutes. 

When it comes to generator surging, it refers to the generator’s inconsistent or fluctuating power output, which can cause lights to flicker or appliances to malfunction. Is your generator doing the same thing? 

Here’s how to fix it!

How to Fix a Surging Generator

How to fix a surging generator,

1. Check the Fuel System

When it comes to generator surging, the fuel system often takes the blame and it should always be the first thing you check before any other part of your generator. 

You should start by inspecting the generator fuel tank to succinctly ensure that there’s an adequate supply of clean fuel in the tank. 

Why I said you should start with the fuel system, especially the tank because fuel is a substance that deteriorates or becomes contaminated over time, which might lead your generator to perform poorly when needed. 

Therefore, if you have checked and it appears that the fuel in the generator tank is old or contaminated, you must drain the tank and replace it with fresh fuel. 

After that, you should direct your attention to the fuel filter. A clogged or obstructed fuel filter can disrupt the fuel flow and contribute to surging. Take the time to clean or replace the filter as necessary, allowing for unimpeded fuel delivery.

2. Clean the Carburetor

After you are done with the fuel system and it continues, your carburetor might be at fault. That’s because, when a carburetor is dirty or clogged it can cause the generator to surge. 

Firstly, you should locate the carburetor, which is typically positioned near the engine. With care, remove the air filter cover and filter itself. 

Then take a moment to inspect the carburetor for any signs of dirt, debris, or varnish buildup. These substances can impede the proper functioning of the carburetor and result in surging. 

Using a carburetor cleaner, diligently spray the cleaner into the various openings of the carburetor, ensuring that all internal parts are thoroughly cleaned. 

Once completed, reassemble the carburetor and air filter, making sure everything is securely in place. 

However, not everyone can clean their carburetor themselves, and if you think it’s something hard or you haven’t done it before, please invite a professional to help.

3. Adjust the Governor

Thirdly, if it continues, check and adjust the governor’s control. The governor’s control plays one of the most important roles in maintaining a stable power output by regulating the engine’s speed. 

If your generator is experiencing surging, it may indicate an issue with the governor’s adjustment. To rectify this, locate and adjust the governor control. This can also be a bit technical, so a professional is needed in this aspect.

But if you can do it yourself, the adjustment process may involve tightening or loosening a spring or making small changes to a screw. By doing that, you can work towards achieving the desired stability and smooth operation.

4. Inspect the Spark Plug

After you are done with the governor control, also inspect or even change your spark plug if necessary. 

Start by using a socket wrench to remove the spark plug, and carefully examine it for any signs of damage, such as erosion or fouling. 

Just like every other thing in the world, spark plugs can also deteriorate and become less effective, negatively impacting the generator’s performance. 

If the spark plug appears worn or damaged, replace it with a new one of the correct size and heat range. 

Before reinstalling the spark plug, ensure it is properly gapped the spark plug ensuring allowance for optimal ignition.

5. Check the Air Intake and Exhaust System

Fifthly, if you are done with the spark plug replacement or clean, also check the generator’s air intake and exhaust system.

Start by checking the air filter for any accumulation of dirt, debris, or clogs. A clean and unobstructed air filter ensures proper airflow, which is essential for efficient generator operation. 

If necessary, clean or replace the air filter to restore unrestricted airflow. Similarly, inspect the exhaust system for any blockages or damage that may restrict the flow of exhaust gasses. 

If you have inspected it and there are, clear the obstructions and repair or replace damaged parts, ensuring the generator can breathe freely.

6. Evaluate the Load

Sixthly, ask yourself are you using the right load of the appliances for the generator? Overloading your generator can also lead to surging issues and at the same time reduce your generator’s performance. 

It is important to ensure that the total electrical load connected to the generator does not exceed its maximum capacity. 

Take a moment to reassess the load and unplug any unnecessary appliances or equipment that may be overburdening the generator. 

But if the surging persists even with a reasonable load, and you have carefully done all steps in this blog post, it’s time to proceed with further troubleshooting steps.

7. Seek Professional Assistance

So, if you have diligently followed all the troubleshooting steps and the generator continues to surge, it may be necessary to seek the expertise of a professional technician. 

These specialists possess the necessary knowledge and tools to diagnose and repair complex issues that may be affecting your generator’s performance. 

By reaching out to any professional around your area, you can gain insights into any underlying problems and receive the best possible solution for restoring your generator’s functionality.

Generator Hacks as a fast-growing community has been existing for years solving issues on generators and showing generator owners the best ways to fix or troubleshoot their generators themselves, and if they are not able to, we have professionals ready to help. 

Therefore, fixing a surging generator may require a systematic and patient approach, starting with the fuel system and gradually moving on to other components such as the carburetor, governor, spark plug, air intake, and exhaust system. 

But if you’ve taken every step in this blog post, but the problem persists, then it’s the right time for you to seek professional assistance from anyone around.
