Our experienced technicians diagnose Generac, Kohler, and other major brands to catch hidden battery or fuel failures.

Common Generator Problems We Fix

The generator calls we get across Huntersville and Cornelius usually come down to a few recurring culprits.

The most common reason a standby generator fails to start is a battery that quietly died between outages. Because the unit only cranks a few times a year, a weak battery goes unnoticed until it matters. We test and replace it and confirm the charging system is keeping it topped off.

Fuel that sits too long breaks down and gums up the carburetor and lines, especially on units that rarely run. That is often what causes a generator to start and then stall. We clean or rebuild the fuel system and get the engine running cleanly again.

The transfer switch senses an outage and hands the load to the generator, so a fault there can leave a good engine sitting idle. These issues are easy to miss without testing the full sequence. We check the switch and controller so the handoff actually happens when the grid drops.

Roland Black: Your Local Generator Repair Experts

Roland Black is licensed in North Carolina and South Carolina with a BBB A+ rating, and our team works on the standby generators homeowners across the Lake Norman area rely on. With same-day scheduling and 24/7 emergency availability, we are there when a unit fails at the worst possible time.

  • Why won’t my standby generator start during an outage? A no-start is most often a dead battery, stale fuel, or a fault in the automatic transfer switch, and the only way to know is a proper diagnostic. We test the battery, fuel system, and controller to find the real cause, then give you an upfront price. Call (980) 206-3523 and we will prioritize the visit.
  • My generator runs for a minute and then shuts off. What’s wrong? Starting and then quitting usually points to a fuel-delivery problem, a clogged carburetor on older units, or a sensor cutting the engine on a fault. It is a common pattern and usually fixable without a full replacement. We track down which system is dropping out, correct it, and run the unit under load to confirm the fix holds.
  • Can regular maintenance prevent most generator repairs? Largely, yes. Most emergency failures trace back to a unit that sat untested until the power went out. Annual service that changes the oil and filter, checks the battery, and runs the generator under load catches problems while the lights are still on.

We repair the standby generators that keep Huntersville and Cornelius homes powered through outages. When a unit is past repair or you are adding backup power for the first time, we handle generator installation. Because a generator is only as good as the system behind it, we also offer electrical panel upgrades and whole-home surge protection.

  • The unit won’t start or auto-start when the power goes out.
  • It runs for a minute, then shuts down.
  • A warning light or error code on the controller.
  • It hasn’t been serviced or run under load in over a year.
  • Unusual noise, smoke, or fuel odor during operation.

A generator that fails mid-storm helps no one. Call Roland Black at (980) 206-3523 to get yours diagnosed and running, with 24/7 emergency service and financing available on approved credit.
