Modern electrical systems are reliable, but they still go down often. Big storms, accidents, and other unforeseen events can cause a power outage. This is why millions of people have generators for backup power. A reliable generator offers you peace of mind when an unexpected power outage happens. Whether you rely on power to run your business or to keep your family safe and warm, a generator is vital during power outages. For a generator to be ready to spring into action at a moment’s notice, it requires maintenance. Without maintenance, your generator can fail, leaving you in the dark when you need it the most.
While generators are designed to be durable, they require routine maintenance and timely repairs to function efficiently and safely. Most models are powered by combustion engines that are subject to wear and tear. Waiting for a complete breakdown before calling for help is a costly, risky approach. It could leave you without power altogether. Instead, we encourage you to pay close attention to the subtle signals your generator gives you. These warning signs are clear indicators that your unit requires professional generator repair or maintenance. If you notice any of the following six signs, it’s time to contact our experts for an inspection and service.
1. The Generator Fails to Start or Stay Running
Your generator needs professional attention when it fails to start or stay running. If your unit is slow to turn over, won’t start at all, or stalls shortly after ignition, there’s a problem within the system.
There are numerous potential causes for starting issues, many of which require professional expertise to diagnose and fix properly. The problem could be a faulty ignition switch or battery, issues with the fuel delivery system, or problems with the alternator. Attempting to troubleshoot these complex electrical and mechanical components without proper training could lead to increased damage. When your generator refuses to cooperate, trust an expert to identify the root cause and restore it to normal operation.
2. There Are Visible Leaks Beneath the Unit
When your generator is running, it uses various fluids to keep its components lubricated and cool. If you see any fluid pooling underneath or dripping from your generator, this is a real indicator of trouble. The most common leaks involve oil, fuel, or coolant.
A fuel leak, besides being an obvious waste of expensive fuel, poses a significant fire risk to your home or business. An oil leak can lead to critical component failure due to a lack of lubrication, causing the engine to overheat and seize. Similarly, a coolant leak can quickly lead to overheating. A professional technician can safely identify the source of the leak and make necessary repairs. Our technicians will replace damaged gaskets, hoses, and top off the necessary fluids. This will protect your investment and prevent the risk of failure.
3. The Generator Is Producing Abnormal Sounds or Smells
You should be familiar with the regular operational sounds and smells of your generator. Any deviation from the norm is a big warning sign that something’s wrong. This includes metallic smells, grinding and banging noises, excessive vibration, or a pronounced sputtering sound. These noises often suggest that parts are loose or worn out, resulting in excessive friction.
Abnormal odors are equally troubling. Smelling burning rubber, chemical smells, or the strong odor of stale fuel are all immediate signs of danger. These smells usually point to:
- Friction causing components to overheat
- Electrical wires or insulation burning out
- Old or contaminated fuel in the tank
- A dangerous buildup of exhaust fumes
Professional technicians are trained to identify the exact source of these sounds and smells, preventing a minor issue from escalating into a big one.
4. The Power Output Is Inconsistent or Low
A generator is designed to supply a steady, consistent flow of power when it’s running. If you notice that appliances connected to the generator are flickering, dimming, or not functioning at full capacity, the unit is likely struggling to operate. Something is preventing your unit from maintaining its output voltage or frequency. This low or erratic power output can damage sensitive electronics in your home and indicates a problem within the unit’s regulation system.
Various factors can cause inconsistent output. This includes problems with the voltage regulator, the automatic transfer switch (ATS), or worn-out brushes. Allowing this issue to persist puts both your generator and your electronics at risk. When you call for professional guidance, a technician will use specialized diagnostic tools to test the unit under load. Our team will then isolate the cause of the poor output and calibrate it back to factory specifications.
5. The Generator Is Visibly Rusted or Corroded
Generators, especially standby units, are often installed outdoors and are constantly exposed to the elements. They may be built with weather-resistant materials, but rust and corrosion are inevitable over time. This is especially true in damp or humid climates.
Corrosion often affects the integrity of the unit’s metal housing, making it less resistant to wind and moisture. It can also damage internal electrical connections, fuel lines, and the frame itself. During our routine generator maintenance, we inspect the entire unit for early signs of rust and corrosion. We clean and apply protective coatings to vulnerable areas and, if necessary, replace any corroded parts to prevent failure.
6. The Maintenance Interval Light Is On
Most modern, reliable generators come equipped with built-in diagnostic and maintenance reminder systems. Manufacturers program these systems to track run-time hours and general usage. When the generator reaches a pre-determined usage threshold, it will illuminate a service indicator light or display a specific code.
Ignoring this light is like ignoring the “check engine” light in your car. The light signals that the unit is due for its regular service. This typically includes changing the oil, replacing filters (air and fuel), checking the battery, and conducting a system diagnostic. Scheduling a service appointment as soon as this light appears is the most proactive way to ensure optimal performance and longevity. It’s also the best way to keep minor issues from turning into expensive repairs.
