A torsion spring counterbalance system consists of one or two tightly wound up springs on a steel shaft with cable drums at both ends. The entire apparatus mounts on the header wall above the garage door and has three supports: a center bearing plate with a steel or nylon bearing and two end bearing plates at both ends. The springs themselves consist of the steel wire with a stationary cone at one end and a winding cone at the other end. The stationary cone is attached to the center bearing plate. The winding cone consists of holes every 90 degrees for winding the springs and two set screws to secure the springs to the shaft. Steel counterbalance cables run from the roller brackets at the bottom corners of the door to a notch in the cable drums. When the door is raised, the springs unwind and the stored tension lifts the door by turning the shaft, thus turning the cable drums, wrapping the cables around the grooves on the cable drums. When the door is lowered, the cables unwrap from the drums and the springs are rewound to full tension.[7]
Regardless of the material, you will likely need to perform some regular maintenance tasks. A garage door professional can examine common problem areas to ensure all are working as they should. Additionally, it is necessary to examine the integrity of the door itself, since your garage can be especially vulnerable to security issues if your door is not structurally sound.
10.4 Raise the second bar 90 degrees and insert the first bar. This is "three." Continue winding. If the spring shortens in length, unwind the spring and switch sides - the springs are on backward. Otherwise, continue winding until you reach a count of "30." This is 7 1/2 turns, which is normal for most 7' doors. Longer life springs are wound the same number of turns. Newer steel doors with only one strut on top often need only 7 1/4 turns. On 8' doors count to 34. Each time you insert a bar into the winding cone, listen for the click to let you know the bar is in all the way. Not inserting the bar all the way could cause the cone to explode.

Here are some examples of average new garage door costs, including installation:  

7.5 Slide both springs out toward the cable drums. This is often the hardest part of the job. You may need to file away swollen shaft, set screw burs, drywall or paint. If the shaft is distorted because the garage door installer overtightened the set screws, file the shaft, insert a bar into the cone and tap the bar with a hammer until the cone passes over the enlarged portion of shaft.
Door styles - in addition to the styles just mentioned, it is important to also consider additional features such as windows across the top of the door to provide light inside of the garage, the use of steel or wood frames to give decorative doors added security and stability, and insulation which can reduce energy costs in the attached garage by an impressive 15 to 20%; and

Install the stiffening strut on top of the top section of steel doors with the section lying flat. Then install the opener bracket that replaces the center bracket between the top two sections. While you’re working on the sections, protect them from scratches by putting carpet scraps on top of your sawhorses. Now, slide the rollers into the roller brackets.

While it would be wonderful if door springs lasted forever, the reality is that the simple act of opening and shutting the door multiple times every day isn’t easy. It’s hard on the springs, even though they’re built to do it. Most springs will last for a while, but they won’t last forever. The regular wear and tear of endlessly opening and shutting the door breaks them down and eventually, they’ll need to be replaced.

The power to your garage is out with the door shut, and you need to get your car out or you'll have to take a bus.

Mechanical garage door openers can pull or push a garage door with enough force to injure or kill people and pets if they become trapped. All modern openers are equipped with “force settings” that make the door reverse if it encounters too much resistance while closing or opening. Any garage door opener sold in the United States after 1992 requires safety eyes—sensors that prevent the door from closing if obstructed. Force settings should cause a door to stop or reverse on encountering more than approximately 20 lbs (9.07 kg) of resistance. Safety eyes should be installed a maximum of six inches above the ground. Many garage door injuries, and nearly all garage door related property damage, can be avoided by following these precautions.

Garage door manufacturers typically produce garage doors fitted with torsion springs that provide a minimum of 10,000 to 15,000 cycles and are guaranteed for three to seven years. One cycle is a single opening and closing sequence. Most manufacturers offer a 30,000 cycle spring. However, it is important to remember that if the weight of the garage door is increased by adding glass, additional insulation, or even several coats of paint, the life of the torsion spring may be greatly reduced. Additionally, springs at highly humid environments, such as coastal regions tend to have a significantly shorter cycle life, due to the corrosive cracking.

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.

The winding and unwinding is done at a metal fitting, called a winding cone, attached to the outside end of the spring. You stick a winding bar into one of the four holes in the cone and use the bar as a lever to turn the cone. Once you've completed a quarter turn, insert the other bar into a different hole in the cone and let the bar lever against the closed garage door to hold the spring tension. This allows you to move the original bar to repeat the process, alternating the bars with each quarter-turn. It takes about 30 quarter-turns to fully tension a standard torsion spring. https://youtube.com/e/Z_eZc-kh40c
