Generator Repair
Backup power only helps if it works. We diagnose and repair standby generator systems across Northern Wisconsin — including units we didn't install.
Do you repair standby generators, including ones you didn't install?
Symptoms We Diagnose & Repair
If your standby system is doing any of these, it needs attention before the next outage.
Won't Start or Transfer
The generator doesn't start during an outage, or it starts but power never transfers to the home.
Battery & Charging Issues
A dead or weak battery is one of the most common reasons a standby system fails to start when needed.
Runs Rough or Shuts Down
The engine starts but runs unevenly, alarms, or shuts itself down shortly after starting.
Warning Lights & Alarms
The controller is showing a fault, alarm, or error that needs to be diagnosed.
Transfer Switch Problems
The generator runs but the automatic transfer switch isn't moving the home to backup power correctly.
Failed a Self-Test
The scheduled exercise cycle isn't running, or the system flagged a problem during it.
Generator Repair in Northern Wisconsin
Backup power here has to account for hard winters, rural properties and long distances between neighbors. It shapes how we plan every system.
When you need it most
Generator failures tend to surface in the middle of a Northern Wisconsin winter storm. Diagnosing issues before the next outage is far better than discovering them during one.
Any brand, any installer
We repair existing standby systems from a range of manufacturers — including units originally installed by someone else.
Battery-related failures
Cold weather is hard on batteries, and a weak battery is a leading cause of no-start conditions. It's one of the first things we check.

Frequently Asked Questions
Straight answers to what homeowners and businesses ask us most.
Yes. We diagnose and repair existing standby generator systems from a range of manufacturers, including units installed by another company. Tell us the make and model when you reach out so we can come prepared.
There are several common causes — a dead or weak battery, a fuel supply issue, a controller fault, or a transfer switch problem. A weak battery is one of the most frequent culprits, especially in cold weather. A diagnostic visit identifies the specific cause.
That usually points to the automatic transfer switch rather than the generator itself — the engine is running but the home isn't being moved onto backup power. This is a common issue we diagnose and repair.
Reach out with the details of your system and the problem, and we'll get back to you to schedule a diagnostic visit. Sharing the make, model, and symptoms up front helps us respond efficiently.
