Generator Repair, Before You Need It

A standby generator that won't start is only discovered at the worst possible moment, in the dark, mid-storm. We diagnose and fix the faults, failed self-tests, and dead batteries that keep them from running, so yours is ready when the grid isn't.

A general guide, not a diagnosis. A standby generator stores fuel and electrical energy, so leave internal repairs to us rather than opening it up.

// Why They Fail

The Machine That Has To Work On Its Worst Day

A standby generator has an unusual job. It sits quietly for months, then has to fire up and carry your whole home the one time the power drops. That pattern, long idle stretches followed by a sudden demand for perfection, is exactly what causes most failures.

The usual culprits are simple: a battery that quietly died between storms, fuel or oil issues, a controller that logged a fault and locked out, corroded connections, or a transfer switch that isn't handing over power. None of these announce themselves in the moment you need the generator, which is why they catch people off guard. The good news is that nearly all of them are straightforward to fix once you find them, and finding them early is the whole game. If yours is beyond repair or was never sized right, we can talk through a fresh installation instead.

We service what's out there, with a soft spot for Generac since it's what we install most. Whatever brand sits along the side of your house, we can diagnose why it isn't doing its one job and put it right.

// Common Fixes
  • Dead or weak batteries, the number-one cause
  • Fuel supply and oil-related shutdowns
  • Fault codes and controller lockouts
  • Failed weekly self-tests
  • Transfer switch and connection problems
  • Corroded terminals and worn components
// What Goes Wrong

The Faults We See Most

// NO START

Won't Start

Cranks without catching, or does nothing at all. Usually battery, fuel, or ignition.

// SHUTDOWN

Starts, Then Quits

Fires up then shuts down, often a protective response to low oil pressure or heat.

// NO POWER

Runs, No Power

The engine runs but the house stays dark, pointing at the transfer switch, not the engine.

// FAULT

Locked-Out Fault

A red alarm and a code on the controller mean it stopped itself and needs a read.

// BATTERY

Dead Battery

The quiet killer. A weak battery is the most common reason a standby won't wake up.

// SELF-TEST

Failed Self-Test

The weekly exercise cycle didn't complete, an early warning worth acting on.

// MAINTENANCE

Service Due

A yellow light flagging oil, filter, or battery service that's come due.

// WEAR

Corrosion & Wear

Terminals, sensors, and connectors that age in the weather and need attention.

// The Early Warning

Your Generator Is Already Telling You

Here's the thing most people don't realize: a standby generator gives you plenty of warning before it fails. Once a week it runs a short self-test, and a failed test, a warning light, or a logged code is the unit telling you something's wrong while the sun is still out and there's no pressure.

The trouble is that nobody's watching the side of the house on a Tuesday afternoon. That's where remote monitoring earns its keep. Generac's Mobile Link sends the unit's status to a phone, so a problem surfaces the week it happens, not during the next storm. We can help you set that up, keep an eye on it, and dig into the Generac systems we know best. Catching the warning is what turns a repair into a scheduled visit instead of an emergency.

// Signs To Act On
A failed self-test that didn't complete its cycle
Any warning or alarm light on the controller
A logged fault code even if it seems to run
A unit that hasn't been serviced in over a year
Age on the battery, usually a few years at most
// The Whole Point

The Worst Time To Find Out Is Mid-Storm

A generator that fails when you finally need it is worse than no generator at all, because you were counting on it. Nearly every failure we're called out for during a storm could have been caught on a calm day by a self-test that went unnoticed or a service that was overdue.

That's why we lean so hard on prevention. A periodic service to check the battery, oil, and connections is a small thing that keeps the unit ready, and it pairs naturally with the rest of your home's electrical maintenance. If the worst does happen mid-storm, our emergency line is answered 24/7.

Test The BatteryThe leading cause of no-starts, and a quick, cheap thing to stay ahead of.
Check Oil & FiltersOverdue service is a common reason a unit shuts itself down under load.
Clear Old FaultsA logged code left unread can keep the generator from starting when called.
Confirm The SwitchoverWe verify the transfer switch actually hands power over, not just that the engine runs.

A Few We Got Running Again

ALLENDALEDEAD BATTERY

Silent When The Storm Hit

A homeowner's generator did nothing during an outage. The battery had quietly failed months earlier and no one knew. We replaced it, tested the full start-up, and set them up with monitoring so the next one gets flagged early.

RIDGEWOODSHUTDOWN FAULT

Starting Then Quitting

A unit kept firing up and shutting down seconds later. The controller had logged a low-oil-pressure fault. We traced and fixed the cause, cleared the code, and confirmed a clean run under load.

SADDLE RIVERTRANSFER SWITCH

Engine Ran, House Stayed Dark

The generator ran fine but no power reached the home. The issue was the transfer switch, not the engine. We repaired the switchover so the unit actually does its job when the grid drops.

// Repair Questions

What Homeowners Ask Us

My Generator Won't Start. What Now+
The most common reason is a dead battery, followed by fuel or ignition issues. It's fine to check that the unit is in automatic mode and the gas is on, but don't keep forcing it to crank or open it up, since it stores fuel and electrical energy. Give us a call and we'll diagnose it properly, often the same problem we see again and again.
Do You Only Work On Generac+
No, we service standby generators of most major brands. Generac is what we install and know best, so we're especially quick on those, but whatever unit sits beside your house, we can diagnose why it isn't running and repair it. If you're not sure what you have, just describe it and we'll sort it out.
Why Did It Start And Then Shut Off+
That's usually a protective shutdown. The controller sensed something wrong, most often low oil pressure or overheating, and stopped the engine to protect it. It's the generator doing its job, but it means something needs attention. Don't keep restarting it. Let us find and fix the underlying cause.
What Does The Fault Code Mean+
Standby generators log numbered fault codes on the controller when they stop themselves, each pointing to a category of problem like a battery, oil, overspeed, or wiring issue. The code narrows things down, but reading it accurately and confirming the real cause is where we come in. Note the code if you can and we'll take it from there.
How Often Should A Generator Be Serviced+
A periodic service, generally once a year, keeps a standby unit ready. It covers the battery, oil, filters, and connections, the things that quietly cause no-starts. Between visits, the weekly self-test and remote monitoring do the watching. Regular service is far cheaper than discovering a problem during an outage.
Can You Fix It Before A Storm Is Coming+
We do our best, and it's exactly why we push prevention. When a big storm is forecast, calls spike, so the surest way to be ready is to have the unit serviced before the season, not the day before the storm. That said, if yours fails when you need it, our emergency line is answered around the clock.
Is It Worth Repairing An Older Generator+
Usually, yes. Most failures are batteries, sensors, or connections that are inexpensive to fix relative to the unit. We'll be straight with you, though. If a generator is old, undersized, or facing a repair that approaches the cost of replacing it, we'll tell you honestly and lay out both paths so you can choose.
Should I Set Up Remote Monitoring+
If your unit supports it, it's one of the best things you can do. Generac's Mobile Link sends the generator's status to your phone, so a failed self-test or a fault gets noticed the week it happens instead of during the next outage. We can help you get it running and keep an eye on it with you.
