Why Backup Generators Fail At The Worst Time

A standby generator is a simple promise. The lights stay on when the grid goes out. Most failures trace back to neglected maintenance, incorrect installation, or fuel supply issues. The good news is that nearly all common issues are preventable with routine checks, proper sizing, and timely service.

Flatley’s Plumbing Express has served Chicago’s south, southwest, and west suburbs since 1960. We install permanently mounted systems that start automatically during an outage. We also provide repair, gas piping, and after hours support for systems we service. Below are the top five problems we see and how to solve them.

Problem 1: Generator Will Not Start

Nothing is worse than a silent unit during a blackout. Start failures usually come down to three areas.

1. Battery and charging
   • Low battery voltage or corroded terminals prevent cranking.
   • A failed trickle charger leaves the battery undercharged.
2. Control settings
   • Unit set to Off instead of Auto.
   • Tripped breakers or a cleared fault that was never reset.
3. Fuel supply
   • Closed gas valve, air in the line after work, or an empty LP tank.

Solutions

• Check the control panel and set to Auto. Confirm no active alarms.
• Inspect battery leads for corrosion. Clean and tighten. Replace weak batteries every 2 to 3 years.
• Verify the dedicated charger has power. If not, check its breaker.
• Confirm natural gas valves are open or that your LP tank has fuel.
• If the unit still will not start, schedule service. A technician can load test the battery, verify the charger output, and check ignition and fuel pressure.

When to call a pro

• Repeated start failures, low gas pressure symptoms, or fault codes. Our licensed team can diagnose control boards, pressure regulators, and ignition safely.

Problem 2: Starts, Then Stalls Or Runs Rough

A generator that starts but surges or stalls is telling you fuel and air are not balanced.

Common causes

• Clogged air filter restricting airflow.
• Dirty spark plugs or failing ignition coil.
• Low or fluctuating gas pressure during high demand.
• Water in the fuel system on LP models.

Solutions

• Replace the air filter annually or as the manufacturer recommends.
• Inspect and replace spark plugs at scheduled intervals.
• Have a pro test and adjust gas pressure under load.
• For LP tanks, ensure regulators and lines are free of moisture. Keep tanks filled above the minimum level for cold weather performance.

Why it matters Running rough creates heat and vibration that shorten engine life. A quick inspection prevents expensive repairs.

Problem 3: No Power To The House After It Starts

The engine is running, but the lights stay off. This points to transfer or breaker issues.

Likely culprits

• Main or generator breaker is tripped.
• Automatic transfer switch did not change over.
• Miswired circuits or undersized conductors from a past install.

Solutions

• Inspect and reset the generator main breaker and branch breakers.
• If the transfer switch does not move to generator mode, stop and call a pro. The switch handles utility and generator power and should not be forced.
• Have a licensed technician test the transfer sequence, verify wiring torque, and confirm labeling so essential circuits are correctly served.

Local install note In many Chicago area homes, space and existing gas or electrical routing can be tight. Our team is known for solving these constraints. One customer noted we avoided outside trenching by running a gas line from an interior T, keeping the yard intact while meeting code.

Problem 4: Overheating, Alarms, Or Shutting Down Under Load

Thermal or overload faults happen when the system works harder than it was sized for or when airflow is restricted.

Common triggers

• Blocked intake or exhaust vents due to snow, leaves, or mulch.
• Undersized generator for the real inrush current of HVAC or well pumps.
• Low coolant, failing fan, or dirty radiator on liquid cooled models.

Solutions

• Keep a clear buffer around the enclosure as the manufacturer specifies. In winter, shovel away drifting snow to maintain airflow.
• Review your essential loads. Consider a soft starter for large AC units or upgrade to the correct generator size.
• Inspect coolant level where applicable and schedule a cooling system service if you see leaks or frequent high temp alarms.

Sizing insight Proper sizing is more than total watts. Motor starting current and seasonal loads in Chicagoland winters and summers must be planned. We provide free on site consultations to model your actual start loads and future additions.

Problem 5: Leaks, Smells, Or Excessive Vibration

Any sign of fuel odor, fluid on the pad, or new noise needs attention.

Potential causes

• Loose or aging gas fittings, often after unrelated work on the meter or piping.
• Oil leaks from gaskets or filters.
• Anchoring or pad issues leading to vibration and metal fatigue.

Solutions

• If you smell gas, turn the unit off and call immediately. We are licensed, bonded, and insured for gas piping. We can inspect, pressure test, and repair safely.
• Address oil seepage quickly. Oil loss leads to engine wear and shutdowns.
• Re level or re anchor the unit if the pad has settled. This protects wiring and fuel lines from stress.

Pro Tips To Prevent Generator Problems

• Exercise weekly in Auto mode. Most models perform a brief run to keep systems healthy.
• Replace the battery every 2 to 3 years, even if it still cranks.
• Change oil and filters per the manual or annually with regular outage risk.
• Keep a 3 to 5 foot clearance around the enclosure. Do not stack mulch or snow against louvers.
• Review your load annually. New appliances or an EV charger can change your sizing needs.
• Schedule a start of season inspection before summer storms or winter cold snaps.

Installation Quality Matters More Than Brand

Great equipment underperforms with poor installation. Our crews handle electrical and fuel connections end to end. We coordinate permits and inspections, and we have partnered with respected manufacturers so you can choose the right size from small circuit coverage to whole home power. Permanent outdoor placement with automatic start means peace of mind during every outage.

Service, Repairs, And After Hours Support

When the grid fails, timing is everything. We offer prompt repairs and after hours service for systems we install and maintain. From ignition faults to transfer switch issues, our technicians arrive with the parts and the know how to get you back online. Financing is available for larger upgrades, and our A+ BBB rating reflects decades of local trust.

When To Repair Versus Replace

Consider replacement when:

1. The generator is over 12 to 15 years old and suffers repeated faults.
2. Your home’s load profile has grown and the unit frequently overloads.
3. Major components like the alternator or control board fail out of warranty.

Consider repair when:

1. Issues are isolated to wear items like batteries, filters, spark plugs, or regulators.
2. The unit has been maintained and faults are new and traceable to a single cause.
3. Output and transfer performance remain strong under load testing.

A free consultation can compare repair estimates with the cost and benefits of a new, right sized system.

What Homeowners Are Saying

"This company did the gas piping for our generator. Ceasar was very professional, listened to suggestions and therefore was able to avoid outside trenching and run the gas line directly from a T inside the house. Outstanding workmanship, very knowledgeable, respectful and polite. Highly recommend, great people for any pipe fitting or plumbing work."

Frequently Asked Questions

How often should my backup generator be serviced?

Most manufacturers recommend annual service. Replace the battery every 2 to 3 years, change oil and filters per the manual, and keep the area around the enclosure clear year round.

Why does my generator crank but not start?

Common causes include low battery voltage, closed gas valves, empty LP tanks, or ignition issues. Verify Auto mode, check breakers, and confirm fuel. If it still will not start, schedule a diagnostic.

What size generator do I need for my home?

Sizing depends on essential circuits and motor starting loads. HVAC and well pumps have high inrush current. A free on site consultation will calculate running and starting watts for a right sized system.

Will the generator turn on automatically during an outage?

Yes. Permanently installed standby units monitor utility power and start automatically when an outage occurs, then transfer power back once the grid returns.

Do you handle permits and gas piping in the Chicago area?

Yes. We obtain permits as needed and our licensed team installs and services gas piping, electrical connections, and transfer switches across Chicago suburbs.
