Safety First: Read This Before You Troubleshoot

Working on a generator involves fuel, electricity, and moving parts. If you smell gas, see damaged wiring, or the unit is flooded, stop and call a licensed electrician. Switch the main breaker on the generator to Off, remove jewelry, wear gloves and eye protection, and keep kids and pets clear. Never backfeed a home through an appliance outlet.

• Turn the generator to Off and let it cool before opening panels.
• Close the fuel shutoff valve if you suspect leaks.
• Keep a fire extinguisher nearby rated for electrical and flammable liquids.

Buffalo often sees lake effect storms that drop branches on lines and spike outages. A safe checkup today prevents a dangerous scramble later.

"A professionally installed generator provides seamless backup power during outages. We assess your home’s energy needs and install the right system for maximum reliability."

Reason 1: Dead or Weak Battery

Batteries fail more often than most homeowners think. Cold snaps drain capacity, terminals corrode, and chargers lose function. Your generator’s starter needs strong cranking amps to turn the engine fast enough for ignition.

DIY checks and fixes:

1. Inspect terminals for white or green corrosion. Clean gently with a baking soda solution and a brush, then tighten.
2. Measure voltage with a multimeter. Most standby units use a 12V battery; below 12.4V is weak.
3. Verify the battery charger or trickle charger is powered. Check its breaker and outlet.
4. If the battery is 3 to 5 years old, replace it as preventive maintenance.

Pro help: We test with load, not just voltage. If a charger has failed or a starter draws too many amps, we replace the faulty part and confirm normal start sequence.

"The installation of my new Kohler generator was great. At the end of the two day project, everything was explained to me. Very professional job."

Reason 2: Tripped Breakers or Blown Fuses

If the control circuit lacks power, the generator will not start, even if the battery is good. Storm surges, shorts, or a stuck motor can trip internal breakers or blow a fuse.

DIY checks and fixes:

1. Open the control panel and look for an internal breaker or fuse. Reset once. If it trips again, stop.
2. Check the service disconnect and the outdoor service panel for tripped breakers.
3. Confirm GFCI outlets serving the charger or block heater are not tripped.

Pro help: We trace shorts, test windings, and inspect wiring to NEC and local code. A persistent trip suggests a failing component that needs diagnosis with proper meters.

Reason 3: Fuel Problems (Empty Tank, Closed Valve, or Line Issue)

A generator needs the right fuel at the right pressure. Natural gas pressure drops in a freeze, propane can be low, and diesel can gel or have water contamination.

DIY checks and fixes:

1. For natural gas: Ensure the gas cock at the meter and the generator shutoff valve are fully open.
2. For propane: Check tank level and open the service valve fully. If the tank is under 20%, schedule a refill.
3. For diesel: Look for water in the separator and confirm recent anti‑gel treatment in winter.
4. Inspect visible flexible lines for cracks or kinks. Do not open hard piping.

Pro help: Our electricians coordinate with fuel suppliers, verify regulator sizing, and test for proper pressure and flow. We also perform fuel system maintenance to prevent varnish, sludge, and restriction.

"Very positive experience regarding the installation of our new generator! The entire team was very informative and professional throughout. Highly recommend the Roy's Team!"

Reason 4: Faulty or Dirty Spark Plug

A fouled or cracked spark plug prevents ignition even when fuel and air are available. Soot, oil, or improper gap will stop a cold engine in seconds.

DIY checks and fixes:

1. Remove the plug only when the engine is cool. Photograph wire positions.
2. Inspect for carbon buildup or damage. Clean lightly and re‑gap to the manufacturer spec if you have the chart.
3. Replace if the plug looks worn, glazed, or the insulator is cracked.

Pro help: We replace plugs with the correct heat range, verify ignition coils, and confirm timing. During service, we also check the valve lash on models that require it.

Reason 5: Clogged Air Filter or Blocked Intake

Engines need clean air. A clogged filter or a snow drift against the intake chokes the engine. Buffalo snow can pile up fast, so keep the intake clear after storms.

DIY checks and fixes:

1. Open the air box and inspect the filter. If it is dark or oily, replace it.
2. Clear leaves, snow, and rodents’ nests from the housing and intake screen.
3. Maintain a clear area around the generator per manufacturer clearance specs.

Pro help: We replace filters with OEM or equivalent parts and inspect for mice damage to insulation and wiring. We also check for intake leaks that skew the air‑fuel mix.

Reason 6: Automatic Transfer Switch or Control Board Fault

Your automatic transfer switch detects power loss and commands the generator to start within seconds. If the ATS control circuit or the generator control board fails, nothing happens.

DIY checks and fixes:

1. If safe, test a manual start from the controller. If it starts manually but not on utility loss, the ATS may be at fault.
2. Verify the controller is not in Off or Manual Only.
3. Check the date and time settings. Some units will not run an exercise cycle if the schedule is invalid.

Pro help: We test low‑voltage control wiring, relays, and boards. If needed, we replace ATS components and verify proper sequencing: utility fail, start signal, warm‑up, transfer, retransfer, cool down.

Reason 7: Skipped Maintenance or Overdue Service

Small problems snowball when maintenance is missed. Old oil, weak batteries, dirty fuel systems, and outdated firmware keep a generator from starting when you need it most.

DIY checks and fixes:

1. Review your logbook for the last oil and filter change. Most standby models need annual service or every 100 to 200 hours.
2. Confirm the unit completes a weekly or biweekly exercise run. If not, the schedule may be disabled.
3. Inspect for rodent damage, loose grounds, and vibration‑loosened fasteners.

Pro help: At Roy’s, routine service includes comprehensive inspections, oil and filter changes, battery testing and replacement, fuel system maintenance, and load bank testing. Load bank testing runs the generator under a simulated load to verify real‑world performance and prevent wet stacking in diesel units.

Frequently Asked Questions

How long should a standby generator take to start after a power loss?

Most systems start within seconds once the automatic transfer switch detects utility failure. If yours does not, the ATS or control board may need service.

How often should I service my standby generator?

Plan on annual service or every 100 to 200 hours. Include oil and filter changes, battery tests, fuel system checks, and a full inspection.

What size generator do I need for my home?

Sizing depends on your essential loads. We perform a load assessment to match the generator to your appliances and priorities without overspending.

Do I need load bank testing every year?

If you have a diesel unit, heavy usage, or critical loads, yes. Load bank testing verifies real output and prevents wet stacking.

Can I run a generator on natural gas, propane, or diesel?

Yes. We integrate natural gas, propane, or diesel with safe, code compliant fuel line work and correct regulator sizing for proper pressure.
