What are the top reasons a Generac generator won't start?

The most common no‑start causes are fuel supply issues, a weak starting/battery system, overdue maintenance faults, or a transfer‑switch/safety lockout. Home standby units run on natural gas, liquid propane, or diesel, so any interruption in fuel will stop starting. A properly matched transfer switch is required; installing or operating without one is a code violation and risks backfeeding. Our electricians handle assessment, permitting, installation, and testing across Denver and Aurora.

Quick checks:

• Confirm your fuel service is on and available.
• Leave safety/transfer‑switch diagnostics to a licensed electrician.
