A garage door that won't open in Thornton is one of the most common calls we get, and the cause is almost always one of a handful of culprits. Most are same-day fixes once a tech sees the door.

Living with Thornton's freezing cold and heavy snow means garage doors work harder here than most people realize. ice freezes doors shut and high-altitude sun cracks seals both feed straight into a garage door won't open, which is why our Adams County techs treat the cause, not just the door in front of them.

What might be wrong

Common causes when your garage door won't open

Here's what our local techs check first — and what each one usually means.

A broken spring
If you heard a loud bang recently, a snapped torsion spring is the likely reason the opener can no longer lift the door.
Dead remote or keypad batteries
The simplest fix of all — fresh batteries in the remote or keypad often bring it right back to life.
Misaligned or blocked safety sensors
If the photo-eye sensors near the floor are bumped or dirty, the opener may refuse to run.
A burned-out or unplugged opener
Power loss, a tripped breaker, or a failed opener motor will leave the door dead.
