Torsion springs are usually above the garage door and out of sight, so many people don't even realize they're there! They serve to offset the weight of the door. A garage opener can't open the door by itself - garage doors are simply too heavy. Instead, by letting the weight of the door store energy into the winding of these springs as it is being brought down by gravity, that energy in unwinding can be used help the opener lift the door later on.
Most garage doors have 2 springs, but 1-4 springs is common. These springs handle powerful forces for many years. Despite their reliability however, they must eventually break. A spring will typically last about 10 years depending on usage. If your garage door isn't opening, it's possible the springs have broken and need to be replaced. In some cases a spring isn't broken but isn't winding because the cable that connects the torsion tube to the garage door has snapped.
If your garage door is opening but the opener is having difficulty, you may have just one broken spring. In this case we recommend replacing all springs as soon as possible. Springs are typically installed as sets, so one broken spring means more broken springs soon. But more importantly, a broken spring means that other parts of the garage door system are under increased strain, including the opener itself. This can lead to very rapid wear and damage to these components.
In fact damage from unnoticed broken springs is very common. By replacing a broken set of springs sooner, you can save yourself a lot of time and money.
