How to Know If Your Garage Door Spring Needs Replacement

Garage door springs are the hardest-working components of your door system. When they fail, the entire door becomes inoperable — and attempting to use a door with a broken spring is dangerous. Here are the key warning signs to watch for.

The Door Feels Extremely Heavy

A healthy garage door with functioning springs should feel relatively light when lifted manually. If your door suddenly feels like it weighs hundreds of pounds, one or both springs have likely failed. The springs counterbalance the door's weight, so without them, you're lifting the full load.

The Door Only Opens a Few Inches

If your automatic opener struggles and stops after moving the door just 4–6 inches, this is a classic sign of a broken spring. Modern openers have safety features that stop the door when they detect excessive resistance — which a broken spring causes.

You Heard a Loud Bang From the Garage

Many homeowners describe hearing what sounds like a gunshot from the garage — this is almost always a torsion spring snapping. The stored tension releases explosively when a spring breaks. If you heard this sound and your door won't operate normally, call a professional immediately.

There's a Visible Gap in the Spring

Torsion springs sit on a metal shaft above the door. If you look up and see a gap or separation in the coils of the spring, it's broken. Do not attempt to operate the door.

The Door Closes Too Fast

Springs slow the door's descent on the way down. If your door drops quickly or seems to fall rather than lower, this indicates spring failure or significant spring wear.
