Signs of a Broken Garage Door Spring

A broken garage door spring is one of the most common reasons a door suddenly stops working. The springs carry the full weight of the door, and when one breaks the door can become too heavy to lift safely.

The most obvious sign is a loud bang from above the door, often heard from inside the house. After that bang, the door may not lift at all, or it may feel extremely heavy when you try to raise it by hand.

Other signs include a visible gap in a torsion spring, a door that opens partway and then stops, or an opener that runs but can't move the door. If you notice any of these, stop using the door and request service.

Never try to force a door with a broken spring. The springs are under high tension and the door can fall. A technician with the right tools can inspect the springs and recommend the right repair on site.
