If one of your door springs just broke and you are looking for instructions to decide if you can change the spring or springs safely and correctly, this page should help. DO NOT OPEN AND CLOSE YOUR GARAGE DOOR. Wooden garage doors are heavy and will probably damage or ruin the opener. The tops of steel doors often bend when operated with broken springs.

If you can hear your garage door motor running for what seems like the full amount of time it normally would take to open or close the door, but the door doesn’t move, chances are the disconnect switch has been enabled. Every garage door opener comes with a disconnect switch in case you lose power. This allows you to open or close the door manually so your car isn’t stuck in the garage until the power comes back on.

As mentioned, the only time you should attempt to open a garage door with a broken torsion spring is during an emergency. Otherwise, you should contact a service technician for emergency repairs. We provide same-day garage door service for people just like you who find themselves stuck and unable to move due to a faulty torsion spring. For prompt, reliable service any time of the day or night, please contact us.
Every modern garage door is built with a sensor due to a mandate passed by the government back in the 1990’s that required garage door opener manufacturers to install safety devices. To meet this mandate, most garage doors have a sensor installed on each side of the doorway. They are often referred to as photo eyes since their main function is to maintain visual contact with one another. If that visual contact is broken by an obstruction, then the garage door stops in its tracks. This is meant to prevent the garage door from closing on a vehicle – or even worse, a person.
Garage doors eventually begin to break, look terrible and pose safety risks. How old is your garage door? Have you ever had a safety inspection performed? Garage door safety should always be a top priority as it could cause serious injuries and cost you the expense and trouble of personal injury lawsuits. Our blog will show you what you need to know about garage door safety inspections to assist you with the inspection and upgrades of your home's garage door.

Lower the door and dismantle it by removing the hardware. Lower a double door by recruiting at least two helpers to help with the weight, and place a 2×4 block under the door to prevent smashing a foot or finger when it’s lowered. Remove the sections one at a time by disconnecting the rollers and brackets. If you have windows, tape them to help control flying shards if they break. Then remove the old roller tracks and remaining hardware.
Snap a locking pliers onto the torsion tube to lock it into place while you tighten the drums. Rotate the drum to wind the cable into the winding grooves. Pull the cable as tight as possible before tightening the setscrews. Leave the locking pliers in place and repeat the tightening procedure on the other side. You want equal tension on both sides. Otherwise, the door will open unevenly.
When I called to schedule the repair service, I was transferrd 5 times and spoke with 6 service reps. Each rep was very confused by my request to get my garage door repaired. One rep actually told me that Sears doesn't repair garage doors. I had to tell her that Sears installed the door. When I finally found a rep who could schedule my service, it took one week for the appointment.
One thing to consider - assuming you have 2 springs and an opener, unless the other spring is quite new, you should replace it at the same time, first because it will probably break fairly soon anyway and changing two is only about $50 more than changing one, and because the springs on both sides should be of equal stiffness - if not, then the door will be unevenly weight compensated and try to open cockeyed, increasing wear and risk of damaging the motor. https://www.youtube.com/watch?v=Z_eZc-kh40c&feature=kp
Carter door: Garage doors in Florida come with extra bracing on the back and are wind-loaded to protect against hurricanes. The average with is 350 lbs. but some can weigh as much as 800 lbs. It can cost up to $1,000 dollars to replace a steel two-car garage door and if it’s made of wood it can cost you up to $5,000 dollars. Some customized doors can be as much as 20 – 30k.

They demonstrate that the average homeowner can usually tackle such a project in a nine hour time span and a professional will be able to complete it in roughly five hours. Should it be a DIY project? Not really, most housing experts point out that it is a two-person job, requires advanced carpentry skills, and even knowledge of household electronic systems.

The nucleus of any garage door system is its opener. Easily overlooked, garage door openers are highly complex pieces of equipment, often containing dozens of intricate parts that work simultaneously with one another to consistently raise and lower your door. You'll know that you're getting the best from Sears as it's the home to America's #1 Garage Door Opener Brand, Craftsman*.
Examine the garge door rollers, hinges, tracks, and other hardware for signs of damage that might cause the door to hang up. Lubricate the tracks and hardware with silicone spray or oil. Raise the door slowly, watching it as it lifts. See if it catches on a warped panel or support beam or if an obstruction in the path of the photo eye causes it to stop or reverse. Any part that protrudes into the path of the garage door can cause it to stop.
Overhead garage doors weigh hundreds of pounds, and doors that are not properly maintained or which are equipped with older automatic garage door openers can be safety time bombs. All too common are the tragic stories of garage doors injuring or even killing children or pets who found themselves underneath a closing door. Modern automatic door openers with auto-stop and auto-reverse mechanisms have greatly reduced such accidents, but mishaps can still occur if the door and door opener are not properly maintained.

Warning! If the door is partially open and crooked, don’t touch it. Period. It’s a sign your door is off balance, and it’s usually caused by a problematic cable. It’s likely the door is still under tension from the spring, and one false move could send a 150-pound door crashing down, causing damage or injury, says Vincent Johnson, owner of Garage Door Doctor of Cypress, Texas.


10.4 Raise the second bar 90 degrees and insert the first bar. This is "three." Continue winding. If the spring shortens in length, unwind the spring and switch sides - the springs are on backward. Otherwise, continue winding until you reach a count of "30." This is 7 1/2 turns, which is normal for most 7' doors. Longer life springs are wound the same number of turns. Newer steel doors with only one strut on top often need only 7 1/4 turns. On 8' doors count to 34. Each time you insert a bar into the winding cone, listen for the click to let you know the bar is in all the way. Not inserting the bar all the way could cause the cone to explode. https://youtube.com/watch?feature=youtube_gdata&v=Z_eZc-kh40c
Doors with extension springs have two sets of pulleys (which are sometimes called _sheaves_): one at the end of each spring and one at the top of the vertical door track. They also have two cables on each side. One cable attaches to the bottom of the door, runs up and over the pulley above the door and around the spring pulley and then attaches to the door track bracket. The other cables are safety cables that run through the middle of the springs and are fixed to a track bracket at both ends. These cables restrain the springs if they break under tension. All extension springs must have safety cables.

There’s another reason new doors are superior to old ones: energy efficiency. Keep in mind, garage doors are large, and when they open, they let a lot of outside air into your home. While you may have significant insulation separating your garage from the rest of your home, eventually that temperature differential will start to influence your energy bills.

Replacing torsion springs is done with the door closed. You start by carefully unloading all of the springs (most standard-size doors have two; any broken spring will already be unloaded), using the winding bars. Then, you unbolt the springs from the central rod bracket, disconnect the cables from the pulleys, and loosen the pulleys and slide them off of the rod. Next, you swap out the springs, reinstall the pulleys and cables, and secure the inside ends of the springs to the central bracket. Finally, you wind up both springs (securing them with two setscrew bolts on the winding cones) and test the door for proper spring tension. Often, springs need an extra quarter-turn or two to get the door balance just right.

Although garage door springs can break during any season and at any time, they most commonly break during the winter. This has to do with the temperature change. When the temperature sinks below a specific threshold, the metal will contract. This means it’s extremely possible for your door springs to shrink slightly during the winter months. This is hard on the springs and makes them more likely to break. http://m.youtube.com/watch?feature=player_embedded&v=Z_eZc-kh40c


Torsion-spring doors have a drum-like pulley at each end of the metal rod that runs through the springs. Each pulley has a cable attached to the bottom of the door. The springs and pulleys are fixed to the rod so they all rotate together. When the door closes, the rod turns and winds up the springs, creating tension. When the door opens, the springs release the tension and turn the rod in the opposite direction.
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.

6.13 Lower the second bar to the top of the garage door as you did the first bar. If your shaft is distorted inside the cone, you may need to tap the bar with a hammer as you unwind the spring. Maintain a firm grip on the bar; keep it firmly inserted completely into the cone; and be prepared at all times for the cone to slip, break, explode or snap loose from the shaft and jolt the bar down.


5.1 With the cables still tight on the drums, mark the drums and torsion shaft at each end with a file or a marking pen. If at least one of the springs is still wound, don't touch the cable drums and don't grab the shaft. If the cable breaks, the drum could spin and the cable rip through muscle and bone. If the set screws aren't tight enough, the shaft could spin and cause injury.
Your door’s torsion spring is located approximately one foot from the top section of your door when it is closed. It consists of two large coil springs, and is approximately the length of your arm. Its purpose is to balance the weight of your door so that a door weighing between 160 and 185 pounds is practically weightless to lift. As such, it makes it possible for a garage door opener to raise the door using only ten pounds of pressure.

Grab a tape measure and press the hook between two spring coils and note the length of 20 coils. Then measure 40 coils. Convert the measurements to a decimal (4-1/2 in. to 4.5 in., or 4-1/8 to 4.125, for example). Divide the two measurements by 20 and 40 to obtain the spring's wire diameter. Here's an example: 4.50 divided by 20 = .225-in. wire diameter; 9.0 divided by 40 = .225-in. wire diameter. If the two results match, you've measured correctly.
Inspect the area around your garage door to see if something is blocking the photo eye sensors. Then look at the tracks to see if there is any buildup on the inside. You’ll need to get a step ladder to look at the tracks on the top part of your garage, as it will be difficult to see from ground level. It may also not be a bad idea to proactively wipe down your garage door tracks periodically to prevent this type of buildup from occurring. Running a damp rag along each track should be enough to remove anything that’s lingering on the tracks.
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.

Slide the left spring onto the tube and add the cable drum. When your new springs arrive, put the new left spring (the 1 with the end facing up and to the left) on the torsion tube, making sure that the stationary cone on the end of the spring faces the center bracket. After sliding the new spring into place, replace the cable drum and insert the torsion bar into the left bearing bracket.[9]
