Our Generator Troubleshooting Process

When you call Pure Power Electrical for generator troubleshooting in Jacksonville, here is what to expect:

  • Initial phone consultation: We ask about the symptoms, error codes, and recent history of the generator to help narrow down the possible causes
  • On-site diagnosis: Our electrician visits your home, inspects the generator, tests electrical outputs, checks fluid levels, and uses diagnostic tools to identify the problem
  • Repair estimate: We provide upfront pricing for the repair before starting any work
  • Repair and testing: We make the necessary repairs, test the generator under simulated load, and verify that it starts and runs properly
  • Preventive recommendations: We let you know if any other components are showing signs of wear and provide recommendations for preventive maintenance

Most generator repairs are completed the same day, depending on parts availability. We stock common replacement parts for Generac, Kohler, and other major brands to minimize downtime.

Common Generator Problems and Solutions

Here are the most common generator issues we see in Jacksonville homes and how our electricians diagnose and repair them:

Generator Won't Start:

If your generator cranks but will not start, or does not crank at all, there are several possible causes. The first thing our technicians check is the battery. Standby generators use a 12-volt battery to start the engine, and batteries typically last three to five years before needing replacement. A dead or weak battery is the most common reason a generator fails to start during an outage.

Other common no-start issues include low oil level (which triggers a safety shutoff), an empty fuel tank or closed fuel valve, a tripped circuit breaker in the transfer switch, or a faulty starter motor.

Generator Shows Error Code:

Modern standby generators have digital control panels that display error codes when a problem is detected. Common error codes include overcrank condition, low oil pressure, high coolant temperature, overspeed or underspeed, and transfer switch communication failure. Pure Power Electrical has the diagnostic software and technical manuals needed to read and clear error codes on all major generator brands.

Generator Runs But Produces Low Power:

If your generator starts and runs but is not powering all your circuits or is producing low voltage, the problem is usually electrical rather than mechanical. Common causes include a failing voltage regulator, worn brushes in the alternator, or a faulty capacitor. Our electricians test the generator output voltage and frequency under load to pinpoint the issue.
