Onan generators are known for their reliability and performance. However, like any other machinery, they can encounter problems from time to time. One common issue generator owners face is the presence of fault codes.
Fault codes are indicators that something is wrong with your generator. These codes are displayed on the generator control board’s panel, alerting you to the specific issue that needs to be addressed. Clearing fault codes is essential to get your generator back up and running quickly. In this article, we will guide you through the steps on how to clear Onan fault codes.
Step 1: Accessing the Control Board
The control board is where fault codes are displayed. To clear the codes, you need to access the control board. The location of the control board may vary depending on your generator model. However, it is usually found inside the generator’s housing or near the front. Refer to your generator’s manual for precise instructions on how to access the control board.
Step 2: Identifying the Fault Codes
Before clearing the fault codes, it is crucial to identify the specific codes that are currently displayed. This information will help you to understand the problem and take appropriate actions to resolve it.
Onan generators use a series of beeps and flashes to communicate fault codes. Consult your generator’s manual to identify the meaning of the specific fault codes you have encountered. The manual will have a comprehensive list of codes and their corresponding issues.
Step 3: Clearing the Fault Codes
Once you have identified the fault codes, you can proceed to clear them. Here are the general steps you can follow to clear Onan fault codes:
- Locate the control board’s reset button. The reset button is usually labeled “Reset” or “Clear Codes.”
- Press and hold the reset button for a few seconds. This action will clear the fault codes stored in the control board’s memory.
- Release the reset button and wait for a few seconds to ensure that the codes have been successfully cleared.
After following these steps, the fault codes should no longer be displayed on the control panel. However, it is important to note that clearing the codes does not solve the underlying problem that caused the codes in the first place. If the fault codes reappear after clearing them, it is recommended to consult a professional technician to diagnose and fix the issue.
Troubleshooting Tips
While clearing the fault codes is an important step, it is equally important to troubleshoot the root cause of the problem. Here are a few tips to help you troubleshoot your Onan generator:
- Refer to the generator’s manual for troubleshooting instructions specific to your model.
- Check the fuel level and ensure there are no fuel supply issues.
- Inspect the air filter and clean or replace it if necessary.
- Examine the spark plugs and clean or replace them if needed.
- Verify that the battery is fully charged and functioning properly.

- If the issue persists, contact an authorized Onan service center for further assistance.
Remember, regular maintenance and servicing can help prevent fault codes from occurring in the first place. It is crucial to follow the recommended maintenance schedule provided by Onan to keep your generator running smoothly.
