How often do torsion springs break?

Torsion springs typically break after about 10,000 cycles, which works out to roughly 7 years for an average household using the garage door three to four times a day. Heavy-use households, families with multiple drivers cycling the door eight or more times a day, will see springs break in 4 to 5 years. Light-use households can stretch to 10 years or more. Manufacturers also sell high-cycle springs rated for 20,000 or even 30,000 cycles, which last 12 to 20 years. Springs break sooner when the door is out of balance, when the cables are worn or rusted, when the drums are misaligned, or when the springs themselves have not been lubricated. A loud bang from the garage is almost always a broken torsion spring.
