Essential Generator Maintenance Checklist for Homeowners in Sharon, MA

Heavy storms and Nor’easters are no strangers to our local weather forecasts. That makes reliable backup power a must-have for safety and comfort. A home generator offers peace of mind during outages, but only if well-maintained. 

Crowe Electric is the local leader in expert electrical services in Sharon, Massachusetts, and we want every homeowner to feel confident that their standby power systems will work when needed most. Below, we provide an electric generator maintenance checklist that outlines the basic steps you can follow, as well as the professional services to schedule annually.

Reliability doesn’t happen by accident. It’s the result of consistent, thorough care. Neglecting maintenance can lead to generator failure during an emergency. You could also expose your home to serious hazards like carbon monoxide buildup or electrical fire risks. Skipping out on routine service can also void some manufacturer warranties. 

Think of preventive maintenance as a simple, inexpensive insurance policy for your backup power.  

What’s Included in Professional Generator Maintenance in Sharon, MA?

A competent licensed electrician will follow a thorough electric generator service checklist designed to keep your backup system in peak condition.

Here’s what you can expect during a professional visit:

• Load testing: Technicians simulate a power demand to ensure your generator can handle your home’s electrical needs.
• Electrical diagnostics: This includes testing voltage output, transfer switch function, and grounding.
• Advanced battery testing: Going beyond a simple voltage check, your electrician will test the battery’s internal resistance and load capacity.
• Fuel system flushing: For gasoline or diesel units, techs clean or flush lines to prevent clogging or contamination.
• Software updates: If your generator has a digital control panel, technicians may update firmware and check for diagnostic codes.
• Cooling and exhaust checks: These safety tests are especially important in tightly packed neighborhoods in Sharon.

Home Generator Upkeep You Can Do Yourself

You don’t have to be an electrician to do your part of the work on your electric generator maintenance checklist. Add these steps to your ongoing seasonal home care routine. Put it on your maintenance schedule along with checking your HVAC system filters and smoke detectors.

1. Perform a Monthly Visual Inspection

Walk around your generator to check for oil or fuel leaks, loose wires, corrosion, or debris buildup around the unit. You know that our Sharon winters bring snow and ice, so make sure there’s a clear 3 to 5-foot radius around the generator for proper airflow.

2. Schedule a Generator Oil Change

Just like a car, your generator needs oil to run smoothly. Manufacturers generally recommend an oil change for every 50 to 100 hours of runtime or at least annually. Old oil can thicken and damage the engine, especially during long outages when the generator runs continuously.

3. Keep the Air Filter Clean

Inspect the air filter annually or every 100 to 200 hours of use. A clogged filter restricts airflow, reducing efficiency and power output. Cleaning or replacing it as needed is a key part of your electric generator maintenance checklist.

4. Run the Generator Monthly

Exercising the generator under load for 20 to 30 minutes each month prevents moisture buildup and keeps internal parts lubricated. Test runs also reassure you that the unit is operational before an emergency hits.

5. Complete a Generator Battery Check

Each month, inspect the battery terminals for corrosion and ensure the voltage is between 12.4 and 12.6 volts. This will help prevent starting issues during power outages.

6. Examine the Fuel System

Gasoline degrades quickly, especially in New England’s seasonal temperature swings. Use a stabilizer if your generator runs on gasoline, and check fuel lines for leaks or damage before each test run or usage. For propane or natural gas systems, inspect the connections for tightness and wear.

7. Inspect or Replace Spark Plugs

Once a year, inspect the spark plug for signs of wear or carbon buildup. A faulty plug can prevent the generator from starting, especially when temperatures dip below freezing.
