Signs Your Generator Needs Maintenance
Skipping regular maintenance shortens the life of your generator and increases the risk of failure during a storm. Watch for these warning signs:
Fails to Start During Weekly Self-Test
If your Generac fails its weekly exercise cycle, it needs immediate attention before the next outage.
Unusual Noises or Vibrations
Knocking, rattling, or excessive vibration signals worn components that could lead to costly failures.
Oil or Fuel Leaks
Visible leaks around the engine or fuel system are safety hazards that require prompt professional service.
Low Oil Pressure Warning
Your generator's onboard diagnostic system alerts you when oil pressure drops below safe operating levels.
Overdue Service Interval
Generac recommends annual maintenance or service every 200 hours — whichever comes first.
Reduced Output or Voltage Issues
Inconsistent power output can damage appliances and electronics connected during an outage.
