Why Does My Champion Dual Fuel Generator Keep Shutting Off?

Here are the possible reasons why your Champion dual fuel generator keeps shutting off:


The champion dual fuel generator may turn off after just a few seconds of operation if it is overworked. Overloading is one of the most common reasons why your generator keeps shutting off. Due to the auto switch-off capabilities that are included on most current generators, it will turn off if it detects that it is overloaded. 


The earlier types of generators do not have this safety function, so they will continue to operate even when they cannot adequately power the devices connected to them. 

This safety function, included in newer models, protects your appliances from being overworked and keeps them in good condition for a longer period of time.

Defective Fuel Tank or Pipes 

If your Champion dual fuel generator stops working after just a few seconds of operation, one of the most likely causes is a problem with either the tank or the line that supplies fuel. The fuel tank supplies the engine and carburetor with fuel, which the fuel pipes transport.

It is possible for there to be a pressure build-up within the fuel tank if the fuel does not flow through the pipes as it should. This may result in supply problems. Additionally, the formation of an excessive amount of dust, leaks, damage, and the bending of fuel lines are all potential reasons why the generator stops functioning.

Faulty Engine

Another reason why your Champion dual fuel generator keeps turning off is a defective engine. When you switch on your generator, any problem with the generator's internal engine might cause it to shut down. It is not always easy to identify whether there is a problem with the engine.

Malfunctioning Carburetor

The carburetor is responsible for a significant portion of work since it supplies the spark-ignition engine with the optimal ratio of air to fuel mixture.

Because it is close to the generator's engine, the carburetor is subjected to a significant amount of dirt, dust, and other pollutants, making it more likely to develop a defect. These particles from the surrounding can make their way into the carburetor, which would then impede the fuel flow.

If your carburetor is defective, the generator will be turned off after it has been operating for a brief period. If contaminated gasoline is allowed to remain in the carburetor, it might cause damage to the generator.

Dirty Air Filter

The work of the air filter provides the generator engine with clean air to function properly. As a result, your generator will have issues if dirt and debris are trapped in the air filter.

When the air filter is clogged and unclean, it does not let clean air travel through it. This allows the air to be contaminated. After some time, the engine will turn off when it cannot get enough air from its surroundings.

Wrong Choke Position

Increased fuel flow is achieved by the generator's inclusion of a choke, reducing the amount of oxygen allowed to flow through the carburetor. 

Since there is usually a small amount of gasoline left in the carburetor when you switch on the generator, you have to do this additional step of adjusting the choke before turning it on. If the choke is not at the maximum position, there will be an imbalance between the air and fuel, which will cause the generator to shut down.

Bad Spark Plugs

Spark plugs are what give the spark that ignites the air and fuel mixture, causing the explosion that causes your engine to generate power. This explosion is what makes your engine work. Due to this, the spark plug is an essential component of your generator, and it also plays a significant part in getting your generator started.

If the spark plug in your generator is defective, you will hear a cracking sound when you start it, and it will turn off by itself within a few seconds after that.

Low Oil Levels

Newer generators, like the Champion dual fuel generator, are equipped with a "low oil shutdown sensor" that automatically turns off the machine when it detects that the oil level is dangerously low. The generator will shut off if the amount of oil that is currently present in the system falls below the level that is recommended. 

It is a widespread misunderstanding that your generator will not start if there is insufficient oil in the engine. The reality is that your generator will start, but there is a possibility that it could do irreversible damage to the engine.

You may also notice that your generator is now much louder and operates less effectively as a result of the low oil pressure in the engine.

Faulty Exhaust System

Exhaust gasses are an inevitable by-product of internal combustion engines and are produced by every generator, regardless of the kind of fuel being used. A generator exhaust extension is used to reroute these gases to protect the generator.

If there is an issue with the generator's exhaust system, it will not be possible for the generator to function for more than a few seconds at a time. The generator will stop functioning when it is unable to expel the exhaust.

What To Do If My Champion Dual Fuel Generator Keeps Shutting Off?

The following are things you can do to fix a Champion dual fuel generator that keeps shutting off:

Reduce The Load On The Generator

If your Champion dual fuel generator keeps shutting off, reduce its load. After that, your generator should start working again if overloading is the cause of the problem.

When adding load to the generator, ensure that the generator can carry it. Listening to the generator's noise is another precaution you can take to avoid an overload shutdown. If the noise is louder than usual, reduce the load on the generator to keep it from shutting off.

Check The Oil Level

Be sure to check the generator's oil level. Low oil level is the most common cause of generators shutting off unexpectedly. First, check the generator's oil level to make sure it is at the right level before you switch it on. If not, top it up. Maintaining the correct oil level in the generator is also essential for the generator's trouble-free operation.

Examine The Pipe And Tank

Check the pipelines and the underside of the generator for signs of fuel leaks. Get your fuel tank professionally cleaned to relieve pressure if you see any discoloration. Also, make sure there are no leaks in the gasoline pipes. If there are, have them fixed right away.

Clean Or Replace Air Filter

Maintaining a clean air filter and replacing it properly when necessary is crucial. The most effective method for getting rid of this issue in which your generator keeps shutting off is to clean the air filters. If the filter is too dirty, it is best to replace it with a new one.

Call A Professional

If the problem persists after trying all the above possible solutions, it's time to call in a specialist. A professional will make the diagnosis and help get your generator working again in no time.

How Much Does It Cost To Fix Champion Dual Fuel Generator?

Repairing generators of all sizes, including those with dual-fuel engines, usually cost between $200 and $400. These prices vary based on many factors like location and work involved.

Can Clogged Fuel Cap Cause Champion Dual Fuel Generator Keep Shutting Off?

Yes, the Champion dual fuel generator may keep turning off if its fuel cap becomes clogged. If the fuel cap is clogged with dirt, air won't be able to flow into the tank to fill the void left by the fuel that has been consumed.

In this case, a vapor lock, also known as a vacuum, will occur inside the tank, preventing fuel from leaking. The generator will not be able to receive fuel to run on, and as a result, it will turn off after a while.

Final Words

If your Champion dual fuel generator keeps shutting off, this could result from overloading, defective fuel tank, engine, carburetor, or spark plug.

To fix the problem, you should reduce the load on the generator, check the oil level, replace the air filter, and examine the pipes. You can call a professional if you find it difficult to solve the problem alone.
