Generac Error Code List

Generac error codes alert users to potential issues. Code 1300 signals low oil pressure, which calls for checking oil levels regularly. RPM Sense Loss, displayed as codes 1501, 1505, 1511, or 1515, may require a unit restart. For Overcrank issue (Code 1100), reset the controller and verify gas supply. High RPM (Code 1200/1205) could indicate faulty ignition coils, warranting service dealer consultation. Handling Error Code 1300 involves maintaining proper oil levels and lubrication, with a potential service call if needed. Immediate action is important for Error Code 1900 due to underspeed error. Swift rectification guarantees consistent generator performance.

Key Takeaways

  • Familiarize with common codes like 1300 for low oil pressure or 1900 for underspeed errors.
  • Regularly check oil levels and monitor RPM to prevent issues.
  • Restart the unit for RPM Sense Loss errors like 1501 or 1515.
  • Contact authorized service providers for persistent error codes.
  • Address Error Code 1100 by verifying gas supply and seeking dealer assistance.

Common Generac Error Codes

When troubleshooting Generac generators, encountering common error codes like Low Oil Pressure and RPM Sense Loss is indicative of specific issues that require prompt attention and resolution.

Code 1300, Low Oil Pressure, may signal a potential lack of lubrication, which can lead to engine damage if not addressed promptly. Checking oil levels regularly and ensuring they're within the recommended range can help prevent this error.

On the other hand, RPM Sense Loss, indicated by codes 1501, 1505, 1511, or 1515, could point to issues with the generator's speed monitoring system. Restarting the unit may sometimes resolve this error, but if it persists, contacting an authorized service provider for further diagnosis and repair is advisable.

Troubleshooting Generac Error Code 1100

To troubleshoot Generac Error Code 1100, the initial step involves resetting the controller and restarting the unit. Error Code 1100 typically signifies an Overcrank issue in the generator.

Verify the gas supply and confirm the gas handle position, as inadequate gas flow can trigger this error. If resetting the controller and restarting the unit doesn't resolve the problem, contacting an authorized service dealer is advisable for further assistance.

This error is commonly associated with starting issues and can be effectively addressed with systematic troubleshooting. By following these steps and confirming proper gas supply and handle positioning, Error Code 1100 on your Generac generator can often be resolved without extensive intervention.

Understanding Generac Error Code 1200/1205

After troubleshooting Generac Error Code 1100 related to an Overcrank issue, understanding Generac Error Code 1200/1205 becomes vital as it indicates high RPM detected in the generator. High RPM levels, signified by this error, can potentially stem from faulty ignition coils within the unit. To prevent engine damage and guarantee peak performance, it's essential to address this issue promptly.

Seeking assistance from an authorized service dealer is recommended to diagnose and rectify the root cause of the high RPM. Regularly monitoring the RPM levels of the generator can help in detecting issues early on and maintaining the unit in top working condition.

Taking proactive steps to resolve Error Code 1200/1205 is crucial for the longevity and efficiency of the generator.

Resolving Generac Error Code 1300

Upon encountering Generac Error Code 1300, immediate attention to the low oil pressure in the generator is essential for peak functionality and longevity of the unit. To resolve this issue and guarantee maximum generator performance, consider the following steps:

  • Check the oil level and add oil following the manufacturer's recommendations.
  • Avoid overfilling the engine with oil to prevent low oil pressure problems.
  • If Error Code 1300 persists, a service call may be necessary to address the underlying cause.
  • Proper lubrication and generator maintenance are critical to avoid recurrence of Error Code 1300 and maintain the unit's efficiency.

Dealing With Generac Error Code 1900

When encountering Generac Error Code 1900, immediate service intervention is essential to address the underspeed error caused by a sudden voltage drop. This error, indicating an Undervoltage condition, can have a major impact on the generator's performance.

To diagnose and troubleshoot the underspeed issue linked to Error Code 1900, contacting a service technician is vital. The sudden voltage drop needs to be identified and rectified promptly to make sure the generator operates efficiently.

Through a detailed service intervention, the voltage-related problems can be effectively addressed, preventing potential operational issues. Hence, swift action is necessary to diagnose, troubleshoot, and resolve the underspeed error indicated by Generac Error Code 1900.
