Generators are devices that allow users to get electricity from them once these have been filled with fuel. Many companies manufacture them. Which makes the process to select a certain model difficultly. Aside from this, the features that you will get depend on these models and their specifications.

This is why it so important that you go through them before selecting one for your home. You can even use these in your vehicles like RVs and motorhomes. Though, when it comes to portable generators, Onan is the best brand that you can go for.

However, recently some users have been complaining that their Onan generator stops running when it is hot. If this happens to you as well then here are some steps that should help you in fixing it.

Onan Generator Stops Running When Hot

  1. Check Air Flow

The first thing that you should do is check the airflow for your generator. Usually, when there are a lot of objects blocking it, your device can start to heat up. This is why you must check the surrounding of your unit.

Usually, if you have placed it in a tight corner then this can also cause a problem. Make sure that the space around your generator is available for air to pass through easily. This will ensure that it is not heating up from being completely covered. Aside from this, you can also move in the generator to some location where the winds can hit it easily.

Alternatively, you can install a separate fan unit for your device to ensure that it stays cool. This is a much easier solution but you should keep in mind that your fan should always be running while the device is switched on. This will ensure that you do not run into similar issues again.

  1. Clean the Device

Sometimes the problem can be because your generator has been clogged up with dirt. Most devices like these shake a lot and have open ports. This causes the dirt around it to enter and then get stuck. Sometimes even debris can enter the inlets and outlets of your generator which can cause it to overheat.

Once the temperature reaches a certain threshold, your device will shut down and stop functioning. This is exactly why you should clean up your generator regularly. Make sure that the ports on it are completely cleaned. If you notice that there is any debris stuck then open up the device and clean it up. If you are unsure about the process for this then you can also consult the manual provided with the unit.

Onan has a huge lineup to choose from which means that the process for cleaning up the device can vary depending on your device. This is why you must check the process given specifically for your generator instead of some other. The procedure should help you throughout the cleaning and you will be able to solve your problem as soon as possible.

  1. Check Screws and Fuel Tank

Lastly, if the problem persists then either the screws on your device might have started to come loose. On the other hand, sometimes it can be because the fuel in your tank has started to catch on dirt. If you have kept your device closed for quite some time then this is most likely the reason.

The fuel in the generators can start to thicken up and catch on dirt with time. If this happens then your generator will have problems trying to run on it and will need a replacement. If you are using the device in a cold climate then most fuels can easily thicken up as well.

This is why you should purchase a product that is specifically made for these weathers. It should be from a good brand to ensure that it is reliable. You can then easily take out the old fuel and replace it with the new one to fix the problem.

As for the screws, you should check if all of them are tight. Put in any of these nuts and bolts that have come out or are loose to start using your generator again.
