Storm Season Means It’s Time for a Generator Check-up

storm season means it's time for a generator checkup. A tree knocked over by the wind, pulling a ton of power lines down with it.

A storm hits. 

The blistering wind takes down an old oak on the corner, bringing power lines right down with it.

Your home stays lit while the rest of the neighborhood plunges into darkness.  

Your Generac generator bursts into action. It keeps your lights on, your fridge running, and your family safe. 

This is the ideal scenario. 

To ensure it’s a reality, your generator needs to be in great condition and ready to withstand the upcoming storm season—so let’s make sure it is.

Everything You’ll Learn About Storm Season Maintenance

Why Regular Generator Maintenance is Crucial for Storm Season

It’s recommended you have your generator checked annually or after 400 hours of runtime. 

Proactive Preparation

The best time to schedule this maintenance is before or early in storm season, which is from June through November, so you can ensure your generator performs reliably and efficiently when you need it most. 

Peak Performance

A well-maintained generator runs more efficiently, providing consistent power during extended outages. Regular check-ups keep all components in optimal condition so your generator is always performing at its best and you avoid costly repairs down the line.

Peace of Mind and Reliability

Major storms can be stressful enough. Knowing that your generator has just recently been inspected gives you peace of mind that your backup power system will work reliably during a storm. You don’t have to fret about keeping your home and family safe.

Safety

Regular maintenance minimizes the risk of malfunctions and safety hazards. By keeping all components in good working order, you reduce the chances of dangerous failures that could put your home and family at risk.

Post-Storm Inspections

After a storm has finally run its course, it’s a good idea to inspect your generator and make sure there are no major damages from storm debris or water intrusion. Here are the steps you should take:

Quick Visual Inspection

Start by visually inspecting the generator and surrounding area yourself. Look for any obvious signs of damage, such as dents, cracks, or loose parts. 

Check for any debris or foreign objects around the generator that might have been blown in by the storm.

Also, look for any signs of water intrusion or moisture accumulation. This includes standing water in or around the generator housing or watermarks, streaks, or obvious wet spots on internal components.

Schedule Follow-Up Maintenance

If you notice any issues during your visual inspection, schedule follow-up maintenance as soon as possible. 

A professional technician can perform a more thorough inspection, testing all critical components to ensure they are functioning properly. 

Possible Generator Issues and Their Solutions

Fuel Problems

Contaminated fuel can lead to clogged filters, restricting fuel flow and causing poor performance. 

  • Signs: Difficulty starting, irregular idling, and sudden shutdowns.

  • Solution: To avoid this, you need to have your fuel filters regularly inspected and cleaned and keep fuel tanks clean and free from contaminants. 

Battery Issues

If the battery is weak or old, it may not have enough charge to start the generator, leaving you without backup power when you need it most.

  • Signs: Cranking difficulties or failure to start.

  • Solution: Check and replace weak or old batteries, keep connections clean and tight, and ensure the battery charger is functioning correctly. Regular battery maintenance ensures your generator starts reliably and functions properly during outages.

Oil and Coolant Levels

Low oil levels can lead to increased friction and overheating, while insufficient coolant may cause the generator’s engine to run at higher temperatures. 

  • Signs: Overheating, unusual noises, and warning lights.

  • Solution: Regularly check and maintain proper oil and coolant levels and replace them at recommended intervals. Proper oil and coolant maintenance keeps your generator running smoothly and prevents damage from overheating.

Steps of a Generator Check-up

The check-up for your generator is a 15-point inspection that double-checks every component of your generator.

 

1. Change the Oil and Oil Filter

Includes draining old oil and replacing it with fresh oil as recommended by the manufacturer. Change the oil filter to maintain optimal engine performance and reduce wear and tear.

2. Inspect for Leaks

Examine the generator for any oil or fuel leaks. Check under the generator, around connections, and on hoses. Address any leaks promptly to prevent environmental damage and performance issues.

3. Inspect & Clean Louvers and Fan Blade

Will examine and clean the louvers and fan blades for dirt, debris, or obstructions to ensure proper airflow, which aids in cooling the generator.

4. Battery Check

Test the battery voltage and inspect the connections to ensure they are clean and tight. The battery is crucial for starting the generator, so it must be in good condition. Replacing weak or old batteries as necessary to ensure reliable starts.

5. Clean Battery Terminals

Clean battery terminals with a wire brush, and apply anti-corrosion spray to prevent future decay.

6. Inspect & Clean Enclosure

Will check the generator’s enclosure for damage, rust, or wear and clean the exterior to maintain its appearance and protect against corrosion.

7. Check to Make Sure the Unit is Level

Ensure the generator is sitting on a level surface. Leveling changes over time as the soil underneath your foundation changes, so don’t assume everything is level if it was a decade ago.

8. Inspect the Air Filter Element & Spark Plugs

Examine the air filter for dirt and debris; replace if necessary. Inspect the spark plugs for signs of wear or fouling; replace them as needed.

9. Check & Clean the Air Intake Filter Compartment

Clean the air intake filter compartment to remove dust and debris. Ensure the air intake is unobstructed for efficient air supply.

10. Check Fuel Line Integrity

Inspect the fuel lines for cracks, leaks, or loose connections. Address any fuel system issues promptly to prevent fuel leaks.

11. Check the Generator Control Panel

Review the generator’s control panel for error codes or warning lights. Ensure all controls and indicators are functioning correctly.

12. Complete Electrical Check, Voltage & Frequency

Use a multimeter to check the generator’s voltage and frequency output. Verify that the generator is producing electricity within the specified range.

13. Check the Automatic Standby System and Voltage Regulator

Test the automatic standby system to ensure it starts and switches seamlessly during power outages. Verify the voltage regulator is maintaining stable output voltage.

14. Check Power Transfer

Test the power transfer system to confirm it operates smoothly between utility and generator power.

15. Clean Any Residue from the Generator Transfer Switch

Remove any dust or residue from the generator transfer switch and ensure the switch functions appropriately to maintain reliable power transfer.
