Signs of a broken spring

- Door rises only a few inches
- Opener strains while trying to lift

Torsion and extension spring systems
Torsion springs are commonly mounted on a shaft above the door, while extension springs run alongside the horizontal tracks on some systems. Both types store energy and are part of the door's counterbalance system.
Do not adjust spring tension casually
Spring hardware is under significant tension. Avoid loosening anchors, winding hardware, cable drums, or other tensioned parts if you suspect a spring failure.

Frequently asked questions
Can a garage door opener lift a door with a broken spring?
It may try, but a broken spring removes much of the counterbalance the opener depends on. Stop cycling the opener if the door barely rises or feels unusually heavy.
Does one broken spring mean the whole door needs replacement?
No. A spring failure is typically a component repair issue unless other major damage is also present.
