Garage door spring broken
Sooner Exterior Home Services
A loud bang from the garage with nothing visibly wrong is almost always a spring. The door will look fine and weigh roughly twice what it did.
Do not keep pressing the opener – it is now lifting the full weight of the door and the gearbox fails next. Do not attempt torsion spring replacement yourself: the stored energy causes serious injuries and winding bars are not optional. Standard springs are rated around 10,000 cycles, roughly seven years at four openings a day.
