What To Know

  • While it may not always indicate a serious issue, it’s essential to understand the underlying cause to ensure the safe and efficient operation of your generator.
  • The battery provides power to the generator’s control board, and if it’s not functioning properly, the generator may not be able to operate correctly.
  • A blinking green and red light on a Generac generator typically indicates a serious fault, such as an engine failure or a major electrical issue.

A blinking green light on your Generac generator can be a cause for concern. While it may not always indicate a serious issue, it’s essential to understand the underlying cause to ensure the safe and efficient operation of your generator. In this comprehensive guide, we will delve into the various reasons why your Generac generator might be blinking green and provide practical solutions to resolve the issue.

1. Low Oil Level

One of the most common reasons for a blinking green light is a low oil level. The generator’s oil sensor detects when the oil level drops below a certain threshold, triggering the light to alert you. To resolve this, simply check the oil level using the dipstick and add oil as needed. Make sure to use the recommended oil type and quantity specified in the generator’s manual.

2. Overheating

If your generator is running for extended periods or under heavy load, it may overheat. This can cause the green light to blink as a warning. To prevent overheating, ensure that your generator is properly ventilated and that the air intake and exhaust vents are clear. If the generator continues to overheat, allow it to cool down before continuing operation.

3. Battery Issues

A weak or dead battery can also cause the green light to blink. The battery provides power to the generator’s control board, and if it’s not functioning properly, the generator may not be able to operate correctly. Check the battery terminals for corrosion or loose connections, and replace the battery if necessary.

4. Fuel System Problems

A blinking green light can indicate problems with the fuel system. This could include a clogged fuel filter, a faulty fuel pump, or a malfunctioning carburetor. Inspect the fuel filter and replace it if it’s dirty. Check the fuel pump for proper operation and the carburetor for any blockages or adjustments.

5. Electrical Faults

Electrical faults within the generator can also cause the green light to blink. These faults could range from loose wires to damaged components. If you suspect an electrical fault, it’s best to contact a qualified electrician to diagnose and repair the issue.

6. Control Board Malfunction

The generator’s control board is responsible for monitoring and regulating its operation. If the control board malfunctions, it can lead to the green light blinking. In this case, it’s necessary to replace the control board with a new one.

7. Firmware Update

In some cases, a blinking green light may indicate that a firmware update is available for your generator. Firmware updates can improve the generator’s performance and reliability. Check the manufacturer’s website for any available updates and follow the instructions provided to install them.

If your Generac generator is blinking green, follow these steps:

1. Check the oil level and add oil if necessary.
2. Ensure the generator is properly ventilated and allow it to cool down if it’s overheating.
3. Inspect the battery terminals and replace the battery if needed.
4. Check the fuel filter, fuel pump, and carburetor for any issues.
5. Contact a qualified electrician to diagnose and repair any electrical faults.
6. Replace the control board if it’s malfunctioning.
7. Check for available firmware updates and install them if necessary.

Basics You Wanted To Know

After a power outage, your generator may blink green as it attempts to restore power. This is normal and should stop once the generator is fully operational.

How do I reset my Generac generator after blinking green?

Most Generac generators do not have a reset button. However, you can try turning the generator off and on again to reset it.

A blinking green and red light on a Generac generator typically indicates a serious fault, such as an engine failure or a major electrical issue. It’s recommended to contact a qualified technician for immediate assistance.
