Generator Won't Start After the Storm: Emergency Generator Repair, Any Brand

The power is out, the generator is silent, or it is running and the house is still dark. Before you call, there are five things you can check with a flashlight in two minutes. After that, our generator technicians diagnose and repair standby generators of any brand across Mobile and Baldwin County, nights and weekends during an outage. Certified Generac® dealer; Kohler, Briggs & Stratton, Cummins, Champion and the rest serviced too.

Check These First

Five Things to Check Before You Call

Most no-start calls during an outage are one of these. Check them in order, with the flashlight, without opening anything you need tools for.

  • 1. The controller is in AUTO. A generator left in OFF after service, or switched to MANUAL during a test, will not start on its own. Look at the controller display or the switch and set it to AUTO.
  • 2. The battery. The most common failure. A dead or weak battery cranks slowly or clicks. If the display is dark, the battery is the first suspect. Do not jump it from a car without knowing the unit.
  • 3. Fuel. Natural gas: the shutoff valve at the unit and at the meter are open. Propane: the tank is above 20 percent and the valve is open. After a storm, gas pressure in the neighborhood can also be low; that is the utility's problem, not the generator's.
  • 4. The generator's main breaker. A tripped breaker on the generator itself means the unit runs but sends nothing to the house. Reset it once.
  • 5. The error on the display. Overcrank, low oil pressure, RPM sense loss, undervoltage, low battery. Write down the code and the words exactly; it tells us what to bring.

If none of that starts it, stop cranking and call. Repeated cranking drains the battery and hides the real fault.

If you see downed lines, smell burning or hear buzzing, stay away, keep people and pets clear, and call 911 or the power company first. Then call us.

What Fails During an Outage

The Faults We Find on the Night Calls

✓

Dead battery and corroded terminals

A battery that was fine in May is dead in September, especially on a unit that has not been exercised. Replaced on the spot; terminals cleaned and protected.

✓

Fuel and pressure problems

Closed valves, low propane, a regulator that failed in the rain, or neighborhood gas pressure that dropped when every generator on the street started at once.

✓

Stale oil, low oil and the shutdown that protects you

Low oil pressure shuts the engine down on purpose. Topped up and the leak found, or an overdue service done on the spot.

✓

Controller and sensor faults

RPM sense loss, undervoltage and overcrank codes point to the starter, the fuel solenoid, the ignition or the controller itself. We carry the common parts.

✓

Transfer switch not transferring

The generator runs and the house stays dark: a stuck automatic transfer switch, a blown control fuse, a failed transfer coil or a tripped generator breaker. Tested at the switch, repaired, and the house comes back.

✓

Ran for a day, then quit

Overheating from a clogged intake, a fuel issue that only shows under load, or an engine that was overdue for service before the storm. Diagnosed under load, not by guesswork.

How the Call Goes

From Dark House to Running Generator

1

Call with the brand and the code

The make, the error on the display, and whether it cranks, runs or does nothing. That decides what goes on the truck.

2

Diagnosis on site

Battery, fuel, oil, controller codes, the transfer switch and the output, tested in that order. Most no-starts are found in the first fifteen minutes.

3

Repair with the parts on hand

Batteries, fuel regulators, oil, filters, control fuses and the common Generac® parts ride on the truck during storm season. Bigger parts are ordered with a real lead time.

4

Load test and handoff

The generator run under load, the transfer tested both ways, and what we found written down for your records and, if it applies, the warranty.

Checked the five things and it still won't start? Call now.

Generator technicians nights and weekends during an outage, any brand, with batteries, regulators and the common parts on the truck.

Any Brand

Dealer Service for Generac, Repairs for Everyone

We are a certified Generac® dealer, which means factory training, warranty service and the parts that other shops wait on. It does not mean we only touch Generac. Kohler, Briggs & Stratton, Cummins, Champion, Westinghouse and the portable in the driveway all get the same diagnosis and the same honest answer, and when a unit is not worth repairing we say so.

During an outage the calls run in the order they come in, with maintenance-plan customers first, because a generator that is exercised and serviced every year is the one that starts. If yours did not, the repair visit is the right time to put it on a plan so the next storm is quiet.

Recovery Service When the Grid Is Back

A generator that ran for three days needs an oil change, a filter and a look at the battery and the air intake before it goes back to standby, and the error log on the controller tells us what it struggled with. A unit that failed to start needs the root cause fixed, not just a new battery. We schedule the recovery service in the weeks after a storm, with priority for the units we repaired during it.

If the storm convinced you that a portable in the driveway is not enough, or that an older standby has reached the end, we size and install standby generators as inventory allows, and we tell you the real lead time up front.

Questions & Answers

Generator Won't Start: Questions

Why won't my generator start during the power outage?

Most often a dead battery, a controller left in OFF or MANUAL, a closed fuel valve or an empty propane tank, or a low-oil shutdown. Check those five things first; if the unit still will not start, stop cranking and call. Repeated cranking hides the fault and kills the battery.

The generator is running but the house has no power. What's wrong?

Usually the transfer switch did not transfer, or the generator's own main breaker tripped. Reset the breaker once. If the house is still dark the transfer switch needs to be tested; it is a common and fixable fault.

What does the error code on my Generac mean?

Overcrank means it tried and never fired, usually fuel or ignition. Low oil pressure is a protective shutdown. RPM sense loss and undervoltage point to the starter, the sensor or the controller. Tell us the exact code and words when you call and the right parts come on the truck.

Do you repair brands other than Generac?

Yes. Kohler, Briggs & Stratton, Cummins, Champion, Westinghouse and portable units. We are a certified Generac dealer for factory warranty work, and we service everything else with the same diagnosis.

Can you come at night or on the weekend during an outage?

Yes. Generator calls during an outage run nights and weekends in the order they come in, with maintenance-plan customers first. The number is the same, and a person answers.

How do I keep this from happening next storm?

An annual service with a battery test and a load test, and a monthly exercise cycle that actually runs. Maintenance-plan customers get both, plus priority service during a storm. We can set it up on the repair visit.
