What's wrong?
Common Standby Generator Problems We Fix
Most failures come from a handful of causes. Here is what we see most in Marlboro yards.
Red light or alarm
Codes like overcrank, low oil pressure or high temperature tell us where to look first.
Missed weekly exercise
If you don't hear the weekly self-test anymore, something has changed in the controller or schedule.
Doesn't take over the load
The generator runs but the house stays dark. That points to the automatic transfer switch.
Runs rough or shuts off
Dirty air filters, worn spark plugs or low oil can make a unit stall under load.
Critter or weather damage
Mice love to chew wiring inside the enclosure. Snow and leaves can block air flow.
Our repair process
How We Diagnose and Repair Your Generator
We find the real cause, fix it, and prove it works before we leave.
Read the controller
We pull the alarm history and error codes to see what happened and when.
Test the basics
Battery, oil level and pressure, fuel supply, air intake and wiring connections.
Check the transfer switch
We test the automatic transfer switch so it can sense an outage and move your home over.
Repair and run under load
After the fix, we run the generator with your home on it to be sure it holds steady.
Preventive maintenance
What Yearly Generator Maintenance Includes
A simple yearly visit prevents most of the calls we get during storms.
Your generator sits idle most of the year, then has to work hard for days at a time. Regular service keeps it ready.
- Oil and oil filter change
- Air filter and spark plug check or replacement
- Battery load test and terminal cleaning
- Check coolant and belts on liquid-cooled units
- Inspect wiring, fuel lines and the enclosure for damage
- Update controller settings and exercise schedule
- Full transfer switch test with the house on generator power
Follow your manufacturer's schedule. Units that ran for many hours during an outage may need service sooner.
Timing
When to Schedule Generator Service in New Jersey
Two visits a year cover the two seasons that matter most in Monmouth County.
Spring
Before summer storms and hurricane season, when JCP&L outages are most common.
Fall
Before winter, when an outage can mean no heat and frozen pipes.
After a long outage
Hours of heavy running wear oil and filters faster. Book a check once power is back.

Owner tips
Simple Checks You Can Do Between Visits
You don't need tools. A two-minute look can catch a problem before an outage does.
Once a month
- Look at the status display. Green or Ready is good. Red or yellow means call us.
- Listen for the weekly exercise on its scheduled day and time.
- Clear leaves, snow, mulch and toys from around the enclosure.
- Make sure nothing is stacked against the air vents.
Before a big storm
- Confirm the unit shows Auto, not Off or Manual.
- If it runs on propane, check the tank level.
- Know where the transfer switch is and what its lights mean.
- Save our number: (732) 419-5195.
Repair or replace?
When Repair Makes Sense and When It Doesn't
We'd rather fix what you have. Here's how we decide.
Repair is usually the answer when...
The engine is sound, parts are still made, and the issue is a battery, sensor, filter, controller board or transfer switch part. Most generators we see fall here.
Replacement may be smarter when...
The unit is very old, parts are no longer available, the engine has major damage, or your home now needs far more power than the unit can supply. We'll tell you honestly and walk you through a new standby install if it comes to that.

Frequently Asked Questions
Why won't my standby generator start?
The most common causes are a weak battery, low oil, a fuel supply problem or a controller fault. Check the display for an alarm code and call us with it.
How often should a standby generator be serviced?
Most homes should have service at least once a year, and after any long outage. Follow your manufacturer's schedule.
Do you repair Generac generators?
Yes. We service Generac, Kohler and Briggs & Stratton standby units, plus most portable generators connected through a transfer switch.
My generator runs but the house has no power. What's wrong?
This usually points to the automatic transfer switch or its control wiring. We test the switch and repair it.
Can you repair my generator during a power outage?
Yes. Our emergency line is open 24 hours. Storm days are busy, so call as soon as you notice a problem.
What does the weekly exercise do?
The weekly self-test runs the engine for a short time to keep parts moving and to catch problems early. If it stops happening, schedule a check.
