How To Fix Ryobi Generator Overload Problem [6 Easy Steps]

In this guide, you will learn what is Ryobi generator overload problem, how to identify it, the main cause, and how to fix it.

Ryobi generators are excellent machines for long-time portable use. These generators are capable of fulfilling the major outdoor and indoor electric requirements. But in issues, there is a major issue which is faced by Ryobi users. It Overloads if you don’t maintain it well

I promise that at the end of this guide, you will be able to solve the overload issue of your generator.

Symptoms Of Overload in Ryobi Generators

Below listed are the main signs of a generator overload. If your generator is facing any one of them you need to immediately switch off your generator and check the reason behind the overload.

Surging or Fluctuating Power Output

If you face multiple fluctuations or surging in your power output it could be a sign of generator overload. It could happen when your electric load surpasses the generator capacity. 

Stalling or Shutting Down

An overload generator may stall or shut down unexpectedly, this happens when the generator safety mechanism tries to prevent your generator from damage.

Overheating of Engine

Overheating can lead to extreme heat build-up in the generator engine. Extreme smoke, a burning smell are signs of overheating in the generator.

Circuit Breaker Tripped

If your generator has a circuit breaker in it or you install an external circuit breaker with your generator it may be tripped while your generator is overloaded. In an overloading case, your circuit breaker may trip continuously.

Unusual Noises In Ryobi Generator

An overloaded generator can cause sputtering or irregular engine sounds. It indicates that you are using your generator at an extreme peak voltage level.

Unstable Voltage

The sometimes unstable voltage output in the Ryobi generator is a sign of overload. You have to use a voltage meter to check, if the voltage is extremely fluctuating this is also a sign of overloading.

How To Fix Overload Problem in Ryobi Generator

If you found any of the above symptoms in your generator you need to follow the below EASY TO FIX Steps to solve your problem in your Ryobi.

  1. Appliance Loads: Check the load and output capacity of the generator. If you have appliances that require more voltage than the capacity of the generator. It will overload, you need to reduce the load on your generator.
  2. Fuel Supply: Check that the generator has enough fuel supply and that the fuel that you are using is clean and recommended by Ryobi. A lack of fuel supply can cause the generator to struggle, which can lead to overloading issues.
  3. Air Inhale and Exhaust Systems: Check the blockage in the Air intake (air filter) and exhaust system of your generator. Blockage of air can also cause overload in the generator.
  4. Oil Level: You need to check the engine oil level of your Ryobi generator. Overloading in the generator is the initial symptom of low oil level moreover, it can cause major damage to the engine of the generator.
  5. Faulty Electric Wiring: If your generator is overloaded you need to check the wiring of your generator. Short circuits in wiring can cause overload and can lead to make fire in the generator.
  6. Hot Environment: operating a generator in a hot condition can also be a possible cause of overload in the Ryobi generator.

Diagnosing Carburetor, Air Filter, and Spark Plug

To troubleshoot the overload problem further in Ryobi generators, we need to check the Air filter, Carburetor, and Spark Plug. Fault or malfunctioning parts can also cause overload in generators and these three are the main parts that you can fix on your own.

Note: To perform maintenance on a covered generator you need to uncover it first.

Cleaning of Air Filter

The air filter takes the air and cleans it for the carburetor to mix it with gas, a dusted air filter can cause the blockage of air. If your generator doesn’t get enough clean air it may lead to overloading the generator. How to fix it?

Ryobi generator air filter location


  1. Turn off the generator if it is running.
  2. Identify the air filter in your generator, it looks like a rectangle box made of plastic. 
  3. After that unscrew the box and take out the foam sheet. 
  4. Clean the foam sheet and the inside of the air box. 
  5. Properly put it back and tighten the screw.

Cleaning or Replacing Spark Plug

A properly functional spark plug is crucial for efficient and smooth engine performance and oil consumption. A spark plug plays a key role in the combustion process and converts the mechanical energy to electric power for the generator.

Ryobi generator spark plug location


  1. Switch the generator off before touching the spark plug.
  2. Locate the spark plug typically located on the side of the generator.
  3. Gently remove the rubber top cover from the spark plug.
  4. Remove the spark plug with the help of a Socket wrench with a spark plug socket.
  5. Examine the spark plug for any fouling, deposits, or damage.
  6. Use a wire brush to remove any carbon or debris buildup.
  7. Check the gap of the spark plug tip and make sure that it is recommended by the manufacturer in the manual. (commonly used 0.025 to 0.030 inches or 0.635 to 0.762 mm).
  8. Put the Spark plug back in the engine and try to avoid cross-threading. Use the socket wrench to tighten.
  9. Check if the rubber cap is connected properly to the wire. 
  10. Put the rubber cap back in the spark plug and start the generator.

Troubleshooting the Carburetor of the Ryobi Generator

In generators, carburetors mix the air and fuel to create a combustible mixture for the engine. The carburetor converts the fuel drops to wappers and mixes them with air. A malfunction or damaged carburetor can cause overload in Ryobi generators.

Ryobi generator carburetor location


  1. Before troubleshooting the carburetor make sure that the generator is turned off.
  2. Locate the carburetor it is typically located near the engine and connected to the air filter.
  3. [Optional] Uncover the air filter and take out the air foam to get better access to the carburetor.
  4. Close the fuel supply from the fuel tank.
  5. Carefully disassemble all components from the carburetor and pay close attention to the gasket screws(engine side).
  6. After removing the carburetor from the engine, make sure all screws and components are kept safe.
  7. Disassemble all parts carburetor and clean it with carburetor cleaner or gasoline.
  8. Check all holes for blockage. Use a steel wire to open it and blow air into it to confirm its cleaning.
  9. Check the gasket and other components for damage, and replace the damaged parts with new ones.
  10. Assemble the carburetor and make sure that all parts are in the correct position.
  11. If you remove the air filter place it back on its position.
  12. Start the generator and run it for about 10 minutes.

Adjusting the fuel supply of the Ryobi Generators

After troubleshooting the carburetor you may need to adjust the fuel supply for your generator. To do that you need to follow the following steps.

  1. Use the manual to identify the fuel adjustment screw, it can be found at the fuel entrance to the carburetor.
  2. Start the generator and let it run for a few minutes to warm up.
  3. If your generator runs normally and the sound is formal you need to do nothing if not follow the next step.
  4. Use a screwdriver the adjust the fuel adjustment screw. Clockwise typically reduces the fuel supply and anticlockwise increases the fuel supply.
  5. Observe the engine while adjusting the screw and notice the changes in engine speed, stability, and smoothness. Adjust it until you get optimal engine performance.
  6. After perfect adjustment, shut down the generator. This adjustment is necessary for fuel efficiency and output load capacity. 

Ryobi Generator Overload While Noting Plugged-In

If your Ryobi generator overloads without any load. You need the address the following issues in your generator.

  1. Check the Fuel supply and make sure it is clean and supply lines are unblocked.
  2. Make sure that the intake and exhaust of air is unblocked.
  3. Clean the air filter and carburetor as mentioned above.
  4. Check the electric wiring of your generator for short circuits.

Conclusion About Ryobi Generator Overload Problem

I hope you solve the overload issue of your Ryobi generator. This is all you can do on your own. There are some issues with the engine that can cause overloading in generators but for that, you need an expert mechanic to make the engine in parts and rewind the engine.
