First and foremost, a garage door, by design, contains springs designed to balance your door and make it easier to lift. Those springs are under incredible amounts of tension. If a spring breaks or is improperly released, it can cause incredible and potentially fatal injuries. Keep in mind, when working on a garage door spring, it is likely that your face and head will be close to it, meaning that your most sensitive area will be in the direct path of the released spring.
If your garage door is equipped with extension springs (usually seen on single car garages), the cable and pulley might be hanging down when the spring break's. Extension springs use a two pulley system on each side of the door to lift the garage door up and down. When the spring break's everything goes haywire, causing the cables to become twisted or even frayed when they catch on the metal edge of the track. There is a lot of force being released when a garage door spring breaks.
If you find yourself with a broken garage door cable, it’s a good idea to leave your garage door alone until a professional arrives to fix the issue. Opening and closing a garage door with a broken cable could cause more damage to the door, resulting in a more expensive repairman visit. No matter the level of the damage, you should definitely leave it up to a professional to avoid any injury.

Garage doors use cable for several purposes. Many people might refer to this as ‘aircraft cable’ – it is a pliable twisted cable of a number of strands of galvanized wire. The primary use for this is a part called a ‘lift cable’. This cable is attached to the bottom corner of the door and then routed to the counterbalance spring as required by the type of counterbalance on your door. The secondary use for cable on many doors is a ‘retaining cable’. This cable is used on overhead type doors with extension or stretch type springs. The purpose of a retaining cable is to assist in preventing an extension spring from falling or flying in the garage in the event of breakage.
The technician, Robert Helton, was very pleasant, helpful, and professional. He repaired the garage door opener expeditiously and explained why it hadn't worked properly. He also checked the chain mechanism and the door itself and showed me how to manually work the door should I need to do that in the future. I was very pleased with this repair work.
Single panel doors can also be installed with (one piece track type hardware) that folds the door back with a single horizontal track on each side (which is mounted at the top of the wood frame) and a roller, (mounted to the top of the door on each side. A hinge on each side that attaches to the bottom of each side of garage door. Using track hardware, a car can be parked much closer to the door, as the whole door, when in the open position, rests completely inside of the garage door header. Track type hardware has much less arc when raising and lowering the garage door as opposed jamb type hardware.
