6 Signs Your Generator May Need Repair

Your home standby generator is critical for your comfort and safety. It is essential to ensure that it is in good repair so that you can rely on it to provide the electricity you need if there is a power outage.

We recommend regularly inspecting your generators to look for signs it may need repair, such as:

Visible Enclosure or Electrical Component Damage

Verify that your generator’s enclosure is not damaged and that all wires are correctly connected and have not loosened. You should also inspect wires for signs of fraying and rodent damage.

Slow Starts

Standby generator systems should initiate operation instantly. Typically, there is a barely noticeable delay — usually around one to two seconds — between grid failure and generator initiation.

If it takes longer for the generator to start, it can indicate an engine or battery problem. Slow starts may also be caused by a clogged fuel valve or carburetor, faulty spark plug, or low oil level.

Low Power Flow

Your standby generator should deliver consistent power flow. If you notice low power flow, it can be caused by a damaged master phase selector switch or problems with the circuit breaker or control panel. 

System Alerts

Many newer standby generators will automatically initiate weekly testing and provide you with a comprehensive diagnostic assessment of system operation. Watch closely for alerts within these reports and act quickly to address potentially critical issues.

Fluid Leaks

You can usually smell oil, coolant, and fuel leaks. Further, these will leave a colored film on top of pooled water.

Inspect fuel lines, hoses, and fuel storage tanks for cracks, tears, and punctures if you suspect a fuel leak.

Battery Charging Issues

If you have a low battery, your generator won’t function properly. Check for signs of corrosion, and use a voltmeter to determine the voltage.

You should replace your generator battery if it’s more than 3 years old.
