Definition
The tightly wound spring mounted on a shaft above your garage door that does almost all the lifting — the opener just guides the door. A torsion spring stores enormous twisting force, which is why a broken one makes a gunshot-like bang and why it should only be replaced by a trained technician with the right winding bars. In the Four-State Area, springs break most often on cold winter mornings, when chilled steel is at its most brittle. Never try to open a door with a broken torsion spring.
