Which generator brands does Roland Black service in Gastonia?

We are Generac Certified and Kohler Certified, and our technicians service those two brands at factory level along with the other major standby generator brands installed across Gaston County. Brand-specific training matters more on generators than it does on most equipment, since controllers and fault codes vary between manufacturers. Our team brings the right diagnostic tools regardless of which brand sits next to your home.

How quickly can Roland Black get to my home for generator repair?

Same-day service is available in most non-storm conditions, with 24/7 emergency dispatch from our Gastonia office through bilingual phone staff. During major storm events, dispatch demand surges across all electrical contractors, and we prioritize active outages and dangerous situations first. We will tell you the realistic timing the moment you call.

My generator failed its self-test, but it ran last time the power went out, so is it broken?

A failed self-test is a real warning sign and worth a service call even if the unit ran during the last outage. Self-tests catch problems that the unit will not survive a long run with, including weak batteries, low oil pressure, controller faults, or fuel system issues. Ignoring a failed self-test is one of the most common reasons a generator fails to start during the next outage.

How often should a standby generator be professionally serviced?

Once a year minimum for full preventive maintenance, and more often if the unit ran heavily during recent outages. Annual service is also required by most manufacturer warranties to keep parts coverage in good standing. Roland Black documents every visit and registers warranty paperwork on your behalf so coverage stays in force.

Can a generator be repaired during an active power outage?

Often yes, depending on the issue. Some failures, like a dead battery or a stuck fuel solenoid, can be repaired on-site even with the grid down, while others require parts that may not be available until conditions allow. Our techs assess the situation honestly and explain options at the door, since a generator that is not coming back online quickly may need a portable backup arrangement in the meantime.

Factory-Certified Generator Service Makes the Difference in Your System’s Lifespan

Standby generators are a category of equipment where brand-specific certification genuinely matters, since the controllers, transfer switches, and fault codes are not interchangeable between manufacturers. Roland Black holds Generac Certified status and Kohler Certified Installer credentials, which means our techs train directly on the equipment they service and can read the diagnostic codes the way the factory intended. Operating a generator safely also means understanding the carbon monoxide risks—which are serious enough that the CPSC maintains a dedicated CO resource explaining why correct installation is not optional on this class of equipment.

Common Generator Problems We Fix in Gastonia

Standby generators sit idle most of the time and are asked to perform under demanding conditions when they finally run, which means they fail in predictable ways. Here are the three most common generator problems we are called out to fix across Gaston County.

A generator that fails to start when the grid drops is the worst case scenario, and the cause is usually one of a handful of issues. Most common are a weak or dead battery, a fuel system that has lost prime, a tripped low-oil-pressure sensor, or a controller fault that has not been cleared since a previous test. Our diagnostic checks each of these in sequence rather than guessing, and we restore start-up reliability rather than just clearing the active fault.

Modern standby generators run scheduled self-tests to verify they will work when needed, and a failed self-test is the unit telling you something is wrong before the next real outage exposes it. Common causes include battery age, fuel system issues, low coolant or oil, controller faults, and ignition problems. We read the controller log to identify the specific fault and address the underlying cause rather than resetting the alarm and walking away.

The automatic transfer switch is what disconnects your home from the grid and connects it to the generator during an outage, and a failing switch can cause anything from a generator that runs without powering the house to dangerous backfeeding into utility lines. We diagnose the transfer switch as a coordinated system with the generator controller, since the issue often lives at the communication between the two rather than in either device alone.

Standby generators fail in distinctive ways, and our team handles the full range of issues that come up across Generac, Kohler, and other major brands.

Failed self-tests are diagnosed by reading the controller log and tracing the fault back to its source.
Battery failures and weak charging systems are tested under load and replaced with manufacturer-spec batteries.
Engine issues, including oil pressure problems, low coolant alarms, and ignition faults, are diagnosed and repaired.
Alternator and voltage regulator faults are tested with proper load equipment to confirm output matches specifications.
Automatic transfer switch failures are diagnosed both at the switch itself and at the connection to the generator controller.
Fuel system issues, including stuck regulators, leaking fuel lines, and dirty injectors, are repaired with manufacturer-approved procedures.
Controller and circuit board failures are diagnosed using brand-specific diagnostic equipment and replaced when necessary.

System repairs don’t have to mean significant delays when you work with Roland Black. Our trucks carry the most common service parts and our techs document repairs against your manufacturer warranty so paperwork is in order if a future issue qualifies for coverage. Contact us today at

Several warning signs tell you it is time to call for generator repair before the next outage tests the unit:

The weekly or monthly self-test has failed or thrown a fault code on the controller display.
The unit ran during a recent outage but struggled to maintain voltage or shut down before grid power returned.
The battery indicator on the controller has been showing a low or weak warning.
You see oil leaks, fuel leaks, or coolant pooling around the generator pad.
The unit makes new sounds during the self-test, including knocking, grinding, or excessive vibration.
The controller display has gone blank, stuck on an error code, or stopped responding.
The transfer switch is making clicking sounds or has stopped switching cleanly during outages.

Any of these warrants a service call before the demand and strain of storm season.
