Understanding Generac Generators

Generac generators are a reliable source of backup power for your home, ensuring that you remain comfortable and your appliances stay on even during an outage. Understanding the basics of how your Generac generator operates and familiarizing yourself with common error codes can help you take control when issues arise.

Basics of Generac Generators

Generac generators are designed to provide a seamless transition to backup power in case of an electrical failure. They are typically powered by natural gas or propane and can be permanently installed as standby units. When your main power supply is interrupted, the generator detects the problem and automatically begins to supply power.

The unit is equipped with a control panel that displays status messages and error codes. It’s important to regularly check and maintain your generator, ensuring that it’s ready to function when needed. Regular maintenance includes checking oil levels, ensuring the battery is charged, and keeping the unit clean and free from debris.

If you experience issues such as your Generac generator keeps tripping, you may need to perform a reset. Detailed generac generator reset instructions can be found in the accompanying manual or on our how to reset generac generator page.

Common Error Codes

Generac generators are equipped with self-diagnostic capabilities that display error codes on the control panel when there is an issue with the system. These codes indicate specific problems that can guide you in troubleshooting and fixing the unit. Below is a table summarizing some of the most common error codes you might encounter:

Error Code Description
1100 Overcrank
1200/1205 Overspeed
1300 Low Oil Pressure
1501/1505/1511/1515 RPM Sense Loss

Each error code has its own set of causes and solutions. For example, if your generator displays an overcrank code, it means the engine attempted to start but failed after several tries. This could be due to issues such as a fuel supply problem or a faulty spark plug.
