You may remember a time as a kid when you and your siblings would close the garage door and run underneath it as fast as possible to make it out before the door closed. Well, on any garage door installed after 1993, that’s no longer possible thanks to two tiny photo eyes on either side of the garage entrance. These photo eyes transmit an invisible beam between each other that detects if anything is in the garage door’s path when it closes. This safety measure is there to prevent automatic garage doors from closing on top of someone or something and causing serious injury or damage to property.
If you notice that the garage door opens normally but doesn’t make any attempt to close when the remote is pressed, the first thing you’ll want to do is visually inspect the photo eyes. Over time, these eyes can get dirty, causing the light from the beam to be blocked. They also can eventually become misaligned, causing the eyes to not match up on both sides.
Your springs may be broken. There are two different types of springs. If your garage door springs are located horizontally at the top of your garage door then it is called a torsion spring. You should check for a gap in between the springs to indicate if they are broken. If your springs are located at either side of your garage door, they are called extension springs. Look to see if a piece of them is hanging on the side of your garage door to indicate if those are broken. If your garage door springs are broken then replacing them is a dangerous process if you have never done it before so you should seek a professional to repair or replace them.
Locating a contractor - there are many professional overhead garage door companies. It is always advisable to contact at least three different agencies and request a bid or quote for the work. Be sure that each quote includes the costs for a few different types of doors, any installation fees, and the cost of wiring the electronic openers. Standard prices range from: http://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.
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. Many garage door pros will charge a service fee to visit your house and determine the problem. Often, the service fee includes a set amount of labor. 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.
When one or both springs break, gravity takes over and you feel the full weight of the door when lifting or lowering it. It may be possible to pull the door up by hand, although doing so will likely be very difficult. In most cases, two or more people are needed to raise the door high enough for you to drive your car out of the garage. While single garage doors can typically be lifted, double doors are nearly impossible to manipulate due to their excessive weight.
If your door has two springs, most professionals and research online says that replacing both springs is the best option. Most torsion springs are rated for 10,000 close/open cycles. If only one of your springs is broken, both springs are still recommended to be replaced. Considering that your second spring will break soon anyways, this added on fix is only going to cost you about $50 extra to assure that you don’t have to pay another service fee for a second visit.
4.4 Take the spring on the left and place it at the left end of the door as pictured here. Notice that the end of the wire points to the right toward the center of the door. This is a right wind torsion spring. It will go above the garage door on the left side of the spring anchor bracket. The winding cone at the other end of this spring is usually painted red.
