How a Uniform electrician diagnoses it
We check battery, fuel, controller logs, and transfer switch operation, then test under load. Repairs and maintenance are quoted in writing.
Repair options
| Option | When it fits |
|---|---|
| Battery and maintenance | Routine items caused the failure. |
| Controller or sensor repair | An electronic fault. |
| Transfer switch repair | The switch didn't transfer. |
| Replacement assessment | An old unit with major failures. See generator service. |
You get a written estimate after diagnosis and before any work starts, including any permit. See what changes a quote in our Naples electrician cost guide.

Frequently asked questions
Why does my generator start for exercise but not in an outage?
Often a transfer switch or controller setting. Bring the error codes.
Is a portable generator through a dryer outlet okay?
No. It's dangerous for you and utility workers. Use a proper inlet and interlock.
How often should it be serviced?
Follow the manufacturer; many recommend at least annually.
