What a working generator changes during an outage
A repaired generator can restore power to the circuits it was designed to serve.
Fault diagnosis helps separate a generator problem from a property wiring or transfer problem.
Testing after repair helps confirm that the generator and connected electrical path work together.
What Generator Repair Covers
Generator Repair is an electrical service that diagnoses and corrects faults affecting generator startup, operation, controls, wiring, or power output.
- Generator repair differs from generator installation because it restores an existing system instead of selecting and connecting a new one.
- Local relevance depends on the generator's property type, connected loads, access, and existing electrical system.
About
What generator repair covers for homes and businesses
Generator repair starts with the symptom you can see. We examine startup controls, wiring, output connections, transfer equipment, and the electrical loads tied to the system. The repair scope depends on the fault and the generator's connection to the property. A unit that runs but supplies no power needs a different check from one that will not start. Our electricians diagnose electrical issues before recommending repairs. We explain the available repair options before work begins, including when an existing part or connection needs closer review.

How we diagnose and repair a generator
Inspect controls and connections
We inspect wiring, controls, transfer equipment, and visible electrical components for damage, loose connections, or signs of a fault.
Test startup and output
We test the starting sequence and power path to determine whether the problem sits in the generator, transfer equipment, or connected circuits.
Define the repair scope
We explain the diagnosed issue and repair options before work begins. The scope follows the parts and connections that failed.
Verify operation
We test the repaired system and check the connected electrical path before the generator returns to normal use.
What to prepare before generator repair
A few details can help us focus the first inspection on the right part of the system.
- Note whether the generator starts, runs, shuts down, or never responds.
- Keep the generator and transfer equipment accessible for inspection.
- Record warning lights, display messages, unusual sounds, or burning smells.
- List the circuits or equipment that lost power during the generator event.
- Share any recent electrical work or changes to connected loads.

Questions about generator faults and repair choices
Who repairs generators for homes and businesses in Indianapolis?
GMB Electric repairs generators for residential and commercial customers in Indianapolis. We diagnose startup, output, wiring, control, and transfer problems before recommending work. Share the generator symptom and property type when you request service. That information helps us understand the system and prepare for a focused inspection.
What should I do if the generator runs but produces no power?
A generator that runs without power needs testing through its output and transfer path. We check the generator connection, transfer equipment, wiring, and affected circuits. Avoid opening energized equipment or repeatedly resetting the system. If you notice a burning smell, sparking, or a buzzing panel, keep clear and request urgent electrical service.
What changes the cost of repairing a generator?
The repair cost depends on the failed part, access, connected equipment, and the amount of electrical work required. We diagnose the fault first, then explain the repair scope and quote details. A startup control issue can require a different repair from an output fault or a problem in the transfer equipment.
Is repairing a generator worth considering?
Repair is worth considering when diagnosis identifies a correctable fault and the system still fits the property's needs. We inspect the generator and connected electrical path before recommending work. The decision should account for the failed component, system condition, repair scope, and whether the generator can serve the required loads safely.
What is the most common reason a generator fails to start?
A failed start can come from the controls, wiring, fuel delivery, or starting components. No single cause fits every generator. We inspect the complete starting sequence and related electrical connections before choosing a repair. Give us any display message, sound, or recent change when you request service.
Should I call an electrician or the utility company during an outage?
Call the utility company for a wider utility outage and GMB Electric for a generator or property electrical fault. We inspect generator startup, transfer equipment, wiring, and connected circuits. If nearby power returns but the generator still fails, the generator system needs electrical diagnosis.

Scenarios
When Customers Call Us About Generator Repair
1
Generator Fails During An Outage
A standby generator may fail to start when the property loses utility power. The fault could sit in the start controls, wiring, fuel path, or another electrical part. We inspect the startup sequence and connected equipment before recommending a repair. Keep people away from damaged wiring, and note any warning message for the service visit.
2
Generator Runs Without Power
A running unit that leaves the building without power points to a fault after startup. Transfer equipment, output wiring, controls, or connected circuits can affect what reaches the property. We test the power path in order, so the repair addresses the failed link. Don't repeatedly reset the system if it produces a burning smell or buzzing sound.
3
Business Needs Backup Power Checked
A business may need generator repair before it relies on backup power for equipment, lighting, or essential circuits. The right scope depends on the connected load and the way the generator feeds the building. We review the symptom, inspect the electrical path, and explain repair options. Clear access to the generator and panel helps us begin safely.
