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
2.3 Beware of older winding cones. These older Crawford and McKee torsion spring cones were made for 5/8" bars. Sometimes, however, the holes are too small for 5/8" bars. Whatever you do, don't use a 1/2" bar; instead, grind down a 5/8" bar to fit. I recently had a McKee spring let loose after winding because I used a 1/2" bar when my 5/8" bar wouldn't fit. Just before it let loose I was telling myself, "This is not safe." And it wasn't. The only safe way to replace these older springs is to make a winding bar for each hole of each cone.
Step 1: Check the metal tracks inside the garage. Look at the mounting brackets that hold the tracks to the walls. If they're loose, tighten the bolts or screws at the brackets. Working inside the garage with the garage door closed, examine the tracks for dents, crimps, or flat spots. If there are any damaged spots, pound them out with a rubber mallet, or with a hammer and a block of scrap wood. If the tracks are badly damaged, they should be replaced.
10.1 It is now time to wind the new springs, but before doing so, I recommend marking the shaft just beyond the winding cone. This is a final step taken to assure that you have installed the springs on the correct sides of the center bracket. Torsion springs always grow in length when they are wound in the proper direction. If your spring does not get longer as you wind it, you are winding it the wrong direction probably because it is improperly installed. We recurrently get calls about springs coming loose from the cones at about 6 turns. If this happens, switch the springs.
The new opener was installed yesterday and today for a while it wouldn't close properly. The customer service representative said they will probably have to reverse the sensors. However, no one could come out today (Friday) or tomorrow. She will call me by Tuesday of next week to schedule someone to come here. The customer service rep. and the technician were nice but as of now, my new garage opener is not working to my satisfaction.
The two main garage door operating mechanisms are sectional roll-ups or tilt-ups. Garage door repair services can fix single-car, double-car or RV-height doors. Your garage door may be made of wood, steel, aluminum, masonite, vinyl, fiberglass or another material. The type of garage door repair you need really depends on the type of garage door you have and the issue at hand. Garage door repair pros often charge a flat service call fee to diagnose the problem and provide an estimate. For customers who choose to have the repair done, the service call fee may be applied to the first hour of labor (including time to make the diagnosis). If your garage door is under warranty, the repair may be free of charge. https://www.youtube.com/v/Z_eZc-kh40c?version=3
A garage door with a broken torsion spring can fall rapidly and cause injury or death. However, the most common danger comes when your torsion springs break and you decide to undertake the repair/replace them yourself. Torsion springs can be very dangerous, and you not only need the exact tools for the job, but also need to have a good knowledge of the mechanics involved. Some of the parts involved in such a process can be life threatening, and must be handled with care and precision, which is why it is always recommended that you call in a professional, rather than trying to handle a replacement or repair by yourself. Failure to do so may leave you with injuries and/or damage to your property.

Test the garage door opener while the door is down. Push the wall button to operate the door opener. If the opener operates, the binding was setting the internal safety mechanisms off, alerting the opener not to close. Raise the door slightly and jiggle the emergency cord to lock the carriage back over the carriage base, and attempt to operate the door with the motor.
It’s difficult to say how often the springs will need to be replaced since it’s different for everyone. It depends on how often you use your garage door, how cold and long your winters are, how well you maintain your springs and many other factors. The best rule of the thumb is to check your springs regularly for signs of wear and damage and to replace them when they begin to appear tired.
Start your garage door spring replacement project by getting a rough measurement of your springs (length and diameter). Then measure the width and height of your door. Make sure the quote includes the trip charge, parts and labor. Then ask for a price based on 7x19 lift cables and double-life springs. Those items will give you more years of service and should only add $65 to the price.

The technician did a wonderful job - arrived on time and completed the job in less than 2 hours. I would have given him a 5 on everything if he had returned to add the additional piece (a piece that is fixed to the door frame for better insulation) to my door on the outside on the day he said he would come back. The piece he brought was of wrong color and he said he would be back with the right color the first day after New Year's Day to put up the piece. I hope he can come back soon.
Next, if you don’t find an obstruction, check the springs. If your door has torsion springs, which are horizontal at the top of the door, you can tell they are broken by checking for a gap between the two springs. If your door has extension springs, you can check by looking to see if they are hanging on the side of the door. If you have a broken spring, you’ll need to call a pro to replace it as this is a dangerous task. https://www.youtube.com/watch?v=Z_eZc-kh40c
An extension spring counterbalance system consists of a pair of stretched springs running parallel to the horizontal tracks. The springs lift the door through a system of pulleys and counterbalance cables running from the bottom corner brackets through the pulleys. When the door is raised, the springs contract, thus lifting the door as the tension is released. Typically these springs are made of 11 gauge galvanized steel, and the lengths of these springs are based on the height of the garage door in question. Their lifting weight capacity can best be identified by the color that is painted on the ends of the springs. https://m.youtube.com/e/Z_eZc-kh40c
