Your garage door opens and closes with using a storage door torsion spring. In case you lookup near the tracks at the back of your garage door system, you'll usually see one or two massive, tightly coiled metallic springs hooked up to the top of the garage door itself with wires and pulleys.
The motor on your garage door provides the route, but these springs provide the power. They exert a pressure equal to the load of your garage door, so when the motor starts up, the power from the spring lifts the door; when the motor pushes down, the springs allow the door to lower.
These springs must be calibrated appropriately in order for the system to work; they should exert a force equal to the burden of the door. If they don’t pull sufficient force, the motor might be taxed, or the door merely received’t rise. Too much pressure and the door could be broken because it slams up and down.
In most cases, we never have to worry about these springs. However every now and again, the springs can break, and when this occurs, they may have to be changed.
