Troubleshooting Onan Generator Fault Code 15

1. Check Load On Your Generator

Before getting into the troubleshooting steps, you should note that the different models from Onan all have varying specifications and features. This is why the process to fix them can also be slightly different. If you are having trouble with any step then it is recommended that you consult the manual to help you out in finding the different parts.

The error code 15 means that the generator is having problems when trying to go above a frequency of 54Hz. The most common reason for this is that your device might be running on a high load. Considering this, you will have to try switching off appliances that consume a lot of electricity. Switching one or two of these should help you in fixing the problem.

2. Configure Altitude Settings

Onan Generators have a small dial on them that can be used to change the altitude settings on them. These are usually configured for plain areas but if you are visiting a mountainous range.

Then it is quite common that your generator will start running into problems. Luckily, you can fix the problem by adjusting the altitude settings on your device. Make sure that you configure these carefully as increasing the dial too much will just drain the power from your generator instead.

3. Altitude Dial Not Included

Sometimes when trying to configure the altitude settings on your generator. You might notice that the dial for this is not installed on your device. This is quite a common problem and many people have reported running into this. However, if this happens to you then your only option will be to contact your dealer.

They will most likely send you the parts that are required for the configuration and you can install them on your own. The process for this is quite simple so you should not have any issues with it. Although, if your dealer is unable to provide you with the dial then you will have to replace your carburetor with a new one.
