Restore Generator Function When It Fails

Pro Power Electric diagnoses and repairs Generac generator systems for homes and businesses in Charlotte, North Carolina.

Your generator may fail to start during an outage due to a dead battery, clogged fuel filter, faulty ignition module, or error code triggered by low oil pressure. Pro Power Electric repairs Generac generators in Charlotte, diagnosing electrical, mechanical, and control system issues that prevent your backup power from activating. We carry common replacement parts, test each component with diagnostic tools, and restore your generator to reliable operation so it is ready for the next storm or grid failure.

We start by reading error codes from the controller, then inspect the battery, fuel system, ignition coil, and transfer switch connections to identify the cause of the failure. Once we locate the problem, we replace worn parts, clear fault codes, and run a full load test to confirm the generator starts smoothly and powers your selected circuits. In Charlotte, we see repair needs caused by high humidity, pollen buildup in air filters, and voltage fluctuations that stress control boards.

Diagnosing Electrical and Mechanical Failures

We use multimeters, compression testers, and manufacturer diagnostic software to pinpoint failures in your generator's electrical and mechanical systems. In Charlotte, we check battery voltage, starter relay function, spark plug condition, and fuel pressure to rule out simple issues before testing more complex components like the voltage regulator or control board. You will receive a clear explanation of what failed and what must be replaced to restore function.

After repairs, your generator will complete its weekly self-test without error codes and start within the expected time frame when you simulate an outage using the controller. The system will hold steady voltage and frequency under load, and the transfer switch will reconnect to utility power smoothly once the test ends.

We replace batteries, fuel filters, spark plugs, and other wear items on site and order control boards, voltage regulators, or ignition modules if your generator requires parts not stocked on our service trucks. If your generator is older and parts are difficult to source, we discuss whether repair is cost-effective compared to replacement. We do not perform repairs that compromise safety or violate manufacturer service guidelines.

Answers to Repair and Troubleshooting Questions

Homeowners dealing with generator failures often want to know what caused the issue, how long repairs take, and what they can check before calling for service, so we have answered those questions below.

What causes a generator to display an error code?
Error codes indicate issues such as low oil pressure, overcrank conditions, high coolant temperature, or loss of utility sensing. We read the code from the controller and use that information to guide our diagnostic process and identify the failed component.
How often should I replace the battery in my generator?
Most generator batteries last three to five years depending on climate and usage. If your generator fails to start during an outage or displays a low battery warning, we test the battery and replace it if it no longer holds a charge.
Why does my generator start but shut down after a few seconds?
This usually indicates a fuel delivery problem, low oil pressure, or a failed ignition module. We check fuel flow, inspect the oil level sensor, and test the ignition system to determine which component is causing the shutdown.
What should I do if my generator runs but does not power my house?
This suggests a transfer switch issue or a problem with the generator's voltage output. We test the transfer switch operation and measure output voltage at the generator terminals to isolate the fault in Charlotte and restore power to your circuits.
When should I consider replacing my generator instead of repairing it?
If repair costs exceed half the price of a new generator or the unit has experienced multiple component failures in a short period, replacement may be more reliable. We provide repair estimates and discuss replacement options so you can make an informed decision.
