Cracking the Code: Troubleshooting Generac Generator Error Codes

Understanding Generac Generator Error Codes

Generac generators are designed to provide reliable power, but like any complex machinery, they may occasionally display error codes. These codes are critical for diagnosing issues and ensuring that your generator operates correctly.

Common Error Code Overview

Generac generator error codes alert you to specific problems that need attention. Some of the codes you might encounter include:

• Overcrank (Code 1100): When the engine fails to start after two automatic attempts. This may require resetting your Generac generator or checking the gas supply.
• Low Oil Pressure (Code 1300): This indicates the oil pressure is below the required threshold. Checking and adding oil as per the owner’s manual may resolve this issue.
• RPM Sense Loss (Codes 1501/1505/1511/1515): Suggests the generator is not sensing the correct RPM, which may require clearing the alarm, checking the battery, or reducing the load.
• Underspeed (Code 1600): Implies the engine is running below the required RPM, and contacting an authorized service dealer is advised.
• Undervoltage (Code 1900): Points to a drop in voltage output, necessitating a service call.

Troubleshooting Steps

When faced with an error code, the following steps can guide you through the troubleshooting process:

1. Identify the Error Code: Refer to your generator’s display panel to determine the specific error code.
2. Consult the Manual: Use your owner’s manual to understand what the code means and the recommended initial actions.
3. Perform Basic Checks:

• For Overcrank: Try resetting the generator and ensuring the gas is on. If the problem persists, contact an authorized service dealer.
• For Low Oil Pressure: Check your oil level and top up if necessary, taking care not to overfill.
• For RPM Sense Loss: Clear the alarm by pressing the ENTER button twice, reduce the load, and attempt to restart the generator. Check and replace the battery if needed.
• For Underspeed or Undervoltage: These issues are often more complex and typically require professional assistance.

1. Attempt a Reset: Some issues may be resolved by simply resetting the generator. This can clear temporary faults and allow the system to restart cleanly.
2. Reduce Load: If your generator is overloaded, try removing some of the load and then attempting a restart.
3. Check for Resets: Some models have a reset button that can help clear certain conditions.
4. Battery Check: If the generator won’t start, it could be due to a battery issue. Refer to the troubleshooting guide for the battery.

If an error persists after these initial steps, it is best to contact a professional. Generac generators are sophisticated systems, and some issues require the expertise of a trained technician. Always prioritize safety and consult the troubleshooting guide for more detailed instructions.
