If you have a standby generator, you’ve made a smart move. It will prevent you from expensive and inconvenient damage should your house lose power. And, if properly maintained, it can last decades. If not properly maintained, it can break down, and could even negate your warranty.  So here is a checklist of things you need to do to maintain your standby generator.  

What You Can Do to Maintain Your Standby Generator

Here are some things you should do periodically.


  1. Run the generator and ensure it runs without alarms or warnings.
  2. Ensure that the generator is in “Auto” mode for automatic startup.
  3. Make sure that the circuit breaker is closed.
  4. Check for fluid leaks.


  1. Check engine coolant.
  2. Check engine oil.
  3. Check the battery charger.
