Determine the inside diameter of the spring and the size of the coils. Run a tape measure across the opening at one end of the spring. Carefully measure the inside diameter of the spring so you can provide the supplier with this information. Then, use a tape measure to find the length of 10 coils on the spring. Divide the length by 10 to determine the measurement of a single coil.[7]
There are lots of ways your garage door can suffer damage. The tracking might be rusted or broken, the weatherstripping might need to be replaced or the door itself might actually be broken or have a hole in it. After all, garage doors are sturdy but not unbreakable. One component of your garage door in particular that will likely need replacing every so often is the spring.

This technician was very competent and performed the services in an outstanding manner. He also suggested additional items needing work on our garage door opener so that it performs much better. It also appears I ordered the wrong door openers, but he was able to input the correct code so that we can use them. We were very satisfied with all of his services.


To evaluate whether the problem lies with the door or the automatic opener, make sure the door is in the fully closed position, then disengage the opener trolly from the door by pulling the emergency release cord. Try to lift the garage door by hand. If the door opens smoothly by hand, the problem is with the opener. If the garage door still only opens halfway, the problem is with the door.
Torsion springs are normally mounted horizontally above the opening of your garage door. When you pull the door down, cables attached to the bottom corners actually force the springs to wind up, in turn energizing the system. When you open the door, the springs then unwind and their energy transfers to the door, helping it to lift up and making it easier to open.
However, if you lose power and use the disconnect switch, you’ll need to reattach it to use your garage door motor to open and close your door again. Open the door all the way and then reattach this hook. Then try opening or closing the door again with your transmitter, and you should be all set. It will be easiest to reattach this hook when your car is not in the garage, as you’ll need to place a step ladder underneath the motor to reach it.
Standard torsion springs (about $40 each) have a service life of 7,000 to 10,000 open/close cycles. However, you can buy double-life (25,000 cycles) replacement springs for about $65 per spring. If you have a two-spring setup and one spring breaks, the second spring will break soon. So replace them both at the same time. To get the right springs for your door, you'll have to provide the supplier some details. Here's how:
Many jobs around the house are fairly easy fixes. It’s relatively easy to clean out your fireplace, clean the leaves from the gutters or repaint a wall. It’s a different thing to replace your garage door spring. It’s careful work that is almost impossible to do correctly the first time. Garage door professionals spend a great deal of time learning how to do it properly, and even the most detailed instructions won’t make you an expert in the span of a few hours. It can be almost infuriatingly annoying at times and is simply better left to professionals.
When a garage door service company gets a phone call in reference to a broken spring, the first thing the homeowner usually says is “the cables are broken”. This makes sense because the cables on a garage door will fly every which way, fall to the ground, become disconnected from the door, or even get caught in between the garage door and the jamb. It is rare for cables to break or need replacing when a garage door spring breaks. If your garage door has two torsion springs, the second spring will keep the cables tight and on the drums. You will have to look up at the springs to determine if one is broken.
With over 300 independently moving parts, your garage door is a deceptively complex piece of equipment. To help prevent malfunctions and break-downs, it is a good idea to occasionally perform a garage door tune-up to keep all of these parts in good working order. A regular tune-up service by a Sears professional can prevent unexpected door problems and prolong the life of your existing equipment. http://m.youtu.be/Z_eZc-kh40c
