Seeing a red light on your Generac generator can be concerning, but don’t worry—it’s typically a sign that your generator needs attention, not necessarily a major issue. This guide will help you understand what the red light means, how to clear it, and how to prevent it from coming back.
What Does the Red Light Mean?
Generac generators have a status indicator light system:
- Green Light: Everything is working correctly.
- Yellow Light: Maintenance or service is needed soon.
- Red Light: There’s a fault or error that needs immediate attention.
The red light indicates that the generator has detected a fault condition, such as:
- Low oil pressure.
- Low coolant (for liquid-cooled models).
- Overcrank or failure to start.
- High temperature or overheating.
- Other system faults, like a sensor issue.
Steps to Reset the Red Light
Step 1: Check the Control Panel
- Locate your generator’s control panel and check the display.
- The panel will show a specific fault code or error message. Write it down, as it will help you understand the issue and take the right steps to fix it.
Step 2: Fix the Underlying Issue
Before clearing the red light, you must address the fault that triggered it. Common fixes include:
- Low Oil Pressure:
- Check the oil level using the dipstick.
- Add oil if it’s low, ensuring you use the correct type (e.g., SAE 30 or synthetic 5W-30).
- Inspect for oil leaks around the unit.
- Overcrank or Failure to Start:
- Check the battery to ensure it’s charged and properly connected.
- Inspect fuel levels and make sure the fuel valve is open.
- Verify that the air filter is clean and the spark plug is in good condition.
- High Temperature or Overheating:
- Ensure there’s proper airflow around the generator. Remove any debris or obstructions.
- Check the coolant level (for liquid-cooled models) and refill if needed.
- General System Issues:
- Look for loose wires or damaged connections.
- Reset tripped breakers or address any electrical issues.
Step 3: Clear the Fault Code
Once you’ve fixed the issue, you can clear the red light:
- Set the generator to OFF on the control panel.
- Press the ENTER button (or RESET on some models) to acknowledge the fault.
- Turn the generator back to AUTO mode.
The red light should turn off, and the green light will illuminate if everything is working correctly.
When to Call a Professional
If the red light remains on after troubleshooting or if you’re unsure how to fix the problem, it’s time to call a certified Generac technician. Some issues, like sensor failures or internal engine problems, require professional tools and expertise.
Preventing Future Red Lights
- Perform Regular Maintenance:
- Change the oil and filters on schedule.
- Inspect the battery, spark plug, and air filter regularly.
- Test the generator during non-emergency times to catch issues early.
- Keep It Clean:
- Ensure the generator is free from debris, dust, and moisture.
- Monitor Alerts:
- Address yellow light alerts promptly to prevent red light errors.
Conclusion
The red light on a Generac generator is a helpful indicator that something needs attention. By identifying and addressing the underlying issue, you can quickly clear the fault and restore your generator to normal operation. Regular maintenance and monitoring go a long way in keeping the red light off for good.
