Adjusting spring tension on a garage door requires adjusting the torsion or extension springs to balance the door’s weight. This is a dangerous procedure and should only be performed by a trained professional.

Garage door springs are under significant tension and adjusting them incorrectly can cause serious injury. Torsion springs are adjusted by winding or unwinding, while extension springs are adjusted through the cables. Ensuring the correct tension is essential for safe and efficient door operation.
