9.15 Install the bolts to secure the stationary center cones to the center bracket. Position the shaft here so it is the same distance from the header as the shaft is at each end. Finger-tighten the nuts until the stationary cones are flush against the center bearing plate. Forcing the cones by tightening the bolts may break a cone if it is catching on a bearing. Winding torsion springs with cracked cones can cause the springs to spin loose and the bars to fly. Secure the bolts.

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.
Check your garage door rollers to see if they have come off their tracks. If no damage has been done, a tech should be able to easily place them back on. If the track has become bent, however, it must be repaired and possibly (depending on the amount of damage) replaced. Don’t operate your door if it's off track or your track is bent. Your door could become seriously damaged.

Sometimes, people unplug their power source and then wonder why their garage door opener fails to work. Sounds ridiculous, I know, but it does happen. Make sure that your garage door opener is plugged into a working outlet. Outlets sometimes go out without warning, so you can check to see if the outlet is working by plugging another working electronic device into it. Also, check your circuit breaker, fuse, or GFCI.
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.

If you have a Wayne Dalton TorqueMaster system (pictured below), the springs will be inside a tube. The only way to determine if one is broken is to lift the garage door manually. If the door is heavy (roughly 60lbs for a double car door), you most likely have a broken spring inside the TorqueMaster tube. Another way to tell if you have a broken spring in your Wayne Dalton Torquemaster tube is if the door goes up and won't go back down. http://m.www.youtube.com/watch?feature=player_embedded&v=Z_eZc-kh40c
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
