6.8 Properly tightened screws will loosen with less than a turn. Once you loosen a set screw, keep at least one bar in the cone AT ALL TIMES until the spring is fully unwound. Many cones have been over-tightened. The spring may unwind 1/4 turn and not unwind any more until one of the set screws is loosened some more. You may need to completely remove the set screws. The shaft may be distorted and the cone still may not unwind at all.
Aging garage door springs cause the door to effectively "weigh" more as the steel loses its resiliency. With new springs, a heavy garage door should take no more than about 10 pounds of force to lift into an open position. With springs nearing the end of their lifespan, the force required to lift the door can be considerably more, since a garage door may weigh 200 pounds or more.
On one-piece doors with side springs, you open the door to relieve the spring tension, and simply swap out the springs on the opener-arm mechanism; there are no cables or pulleys to deal with, and the springs have internal safety rods. Some doors have tensioners that maintain moderate tension when the door is open all the way, and on these you'll have to loosen the tensioner in order to remove the spring.
If you need to leave the door open until you can make repairs, block the door track on both sides so the door can't move, and unplug the garage door opener (if you have one). If you want to close the door, you can try closing it with the opener, making sure there's nothing in the door's path in case something goes wrong. However, this will put some strain on the opener. Alternatively, you can have a few strong helpers hold the door while you disconnect it from the opener and carefully close the door manually—again, it will be very heavy.

My garage door torsion spring broke so I decided to replace it myself. Shipping was next day. I got the torsion spring rod at a local hardware store.

Great replacement spring and save $$$ doing it myself.
Garage door and their openers require basic maintenance. If an emergency occurs, you need to know that your door will open and close. Especially if you have children at home, check the sensors once a month to prevent potential injury. The force setting test lets you know that the door will stop if a child or object is in the way. The photo eye sensors will detect if a child or object is moving under the door and prevent the door from closing. In addition, a complete visual inspection of the system will help to show if something looks out of place or there is obvious damage. Lubricate your springs semi-annually. Investing a few minutes to keep your garage door in tip-top shape may prevent it from getting stuck halfway open or closed.
The garage we take for granted very likely stores thousands of dollars worth of tools and household belongings, not to mention your automobiles. Yet this space is typically rather easy for intruders to penetrate. Garage security can be greatly improved by installing a modern garage door opener that features rotating digital codes, which can foil even the most tech-savvy prowlers.
The history of the garage door could date back to 450 BC when chariots were stored in gatehouses, but in the U.S. it arose around the start of the 20th century. As early as 1902, American manufacturers—including Cornell Iron Works—published catalogs featuring a "float over door." Evidence of an upward-lifting garage door can be found in a catalog in 1906.
If you are not sure if your door had the correct springs, we recommend that you weigh your door using an analog scale. From my own field experience I would estimate that at least 10% of the doors have the incorrect springs on them. In addition to this, most manufacturers spring their doors using a 20 pound window. We like to improve the garage door balance.
Using your drill, add tension to the torsion spring. This system uses a single spring for a double door, but many manufacturers use two springs for a double door. The painted line on the spring acts as a gauge for the number of turns you put on the spring. To keep the bar from turning while you’re adding tension, attach a locking pliers to the bar on both ends of the spring. Apply lubricant for garage doors to the spring.
The national average for garage door repair cost is between $80 and $110. Some of the factors that affect your garage door repair cost are the type of springs (most often torsion or extension), the size and weight of the door, and the door material.

One example of this is an $80 service fee that includes the first hour of work plus testing and inspecting your garage door and garage door opener, while another pro may charge $150 for the same standard service call. https://m.youtu.be/Z_eZc-kh40c
