Garage door springs offset the weight of a garage door and allow the door to be opened and closed easily, either by hand or by an automatic garage door opener. The high-tension steel in the springs has a limited lifespan, and over time, the springs lose their effectiveness. Garage door springs come in levels of quality—they may be described as "10,000-use" or "20,000-use" springs, for example. This may sound like a very large number, but when you consider that a garage door might be opened four or five times a day, every day, every year, it becomes clear that there is a limited lifespan for these critical garage door parts.

9.14 Slide the springs to the bracket. Double-check to make sure you have the right wound spring on the left side and the left wind spring on the right side. Turn the springs until the ends are facing you. The wire at the ends of both torsion springs here at the bracket should be pointing down. At the winding cones at the opposite ends, the spring wire points up. If not, reverse the springs. About once a month we get a phone call from a do-it-yourself customer who begins the conversation with, "I wound the garage door spring to about six turns and the spring came loose from the cone." We normally refer them back to this step and suggest they switch their springs.

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.
As commercial and residential garage door service professionals, we’ve pretty much dealt with every issue you can think of when it comes to garage door repair. Even still, there are sometimes issues that continue to surprise us, like the tiny insect nest growing on the photo eye sensor or the tennis ball that somehow managed to knock the door entirely off its track. Even though these issues are uncommon, it’s nothing that garage door service professionals like us can’t handle!
"Our garage door wouldn’t shut on sunny days and the tech came out. He explained my options (swap the “seeing” sensor with the other, or replace them). He tried swapping and it was still an issue so he replaced them. In addition, he adjusted the spring because the company that installed it last year did not adjust it properly. He was here for about two hours and charged us for only the sensor replacement. Will definitely be using this company again! Highly recommend them. "
Springs are one of the primary components in all garage door systems. Torsion springs are usually mounted horizontally over the door opening. As the door closes, cables add tension to the springs and as the door opens that tension is released. The opening of the door causes the springs to unwind in conjunction with the weight coming off the door. This achieves a natural buoyancy. However, as the door moves up and down over time and the cycle count rises, the steel in the torsion springs will grow weak and will no longer be able to create energy or lift your garage door.
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.

Extension springs last 15,000 cycles. Every time the door goes up and down is one cycle. On average extension springs will last 7 to 12 years. For most people, you know you need to replace your extension springs because it snaps. Sometimes, however, when extension springs get older, they can lose their tension and the spring becomes elongated. This is rare but it does still happen. Basically, the coils are fatigued and when the door is up you can see gaps where the spring is not relaxing properly. When this happens, the spring is useless. It is best to replace the springs at this point rather than overworking the opener which will cause it to last a shorter life.
In this article, we’ll tell you the difference between a safe door and one that’s unsafe. We’ll also give you the helpful tips you’re not likely to find in the manufacturer’s instructions to correctly, and safely, install a new garage door with a torsion spring and do-it-yourself tensioning. Installing a new, double garage door yourself will save you several hundred dollars and should take eight to 12 hours if you’re fairly handy. You can do most of the new garage door installation project yourself, but you should recruit help for removing the old door.
It is very important that the replacement springs are calibrated for the weight of your door. Using the wrong size garage door springs will caused the to not function properly and could also cause the opener to break much quicker. Replacing extension springs can be very dangerous and if done wrong can harm someone using the garage door. Make sure you call the Garage Door Doctor to ensure your garage is repaired properly!

If the door won’t move at all because of an alignment issue, then this problem isn’t one that you should try to tackle yourself. A garage door professional will have the necessary equipment needed to safely realign and repair your garage door. Additionally, if the track misalignment is beyond repair, a professional can install a new garage door track for you.
Instead, try other methods that might break the frozen connection between the door and the floor. For example, you can use a heat gun or hair dryer to melt the ice and free the door. Standard de-icing products can also work. And if you are careful not to damage the door or the seal on the bottom of the door, you can use a flat shovel or similar tool to chip away at the ice.

If your photo eyes are clean and the door still isn’t closing, the next thing you’ll need to do is check the alignment of the eyes. The eyes should be pointing in exactly the same direction and at the same angle. If they’re off, they won’t register that the other one is there, and it’ll assume something is in its path, causing the door to stay in the open position. When checking the alignment, measure the height of each photo eye from the ground. Use a level to make sure they’re pointing directly across at each other at the same angle. A laser level will make this part a little easier, but if you don’t have one, a regular level will work as well.


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.

When cleaning the photo eye, you should take care not to scratch or damage the eye since it’s made of glass, similar to that of a camera lens. The photo eye itself is pretty small, only a few centimeters in diameter, but it can get dirty rather easily. To clean it, you’ll need a soft cloth and a mild, streak-free cleaner. Gently wipe away any dirt or residue that has built up on the eye and be careful not to oversaturate as excessive wetness can cause dirt to stick to the eye more quickly.

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.

As the door is opened and closed over time, the steel in the springs can start to weaken as the door gradually becomes too heavy for them, rendering them less effective. The springs will eventually break, leaving the door closed. Torsion springs can also be affected by rust and cold weather. The good news is, the average garage door torsion springs will last somewhere between 5-7 years, and should last around 10,000 cycles. So, if you open and close your garage door 3-5 times a day for over 365 days in a year, you should get plenty of life out of your torsion springs.
If you have a steel door, but want the look of a wood one, it is not necessary to change your entire garage door. Often, it may be possible to mimic the look of wood with skillful painting. Your local home improvement store may be able to provide good advice about the type of paint and brushes needed to mimic the look of wood for your particular door material.
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.
A garage door with aging springs puts an enormous load on a garage door opener, so another sign of failing springs is when you hear the electric door opener begin to strain as it attempts to lift the door. At this point, it is time to consider replacing the springs. Aging door springs can also break suddenly, a situation that can cause the door to slam shut violently. If you happen to be present when a spring breaks, you will hear a very loud sound like a gunshot, because the break usually occurs when the spring is fully loaded—stretched or twisted to its full tension. When one spring breaks, the door will suddenly feel very heavy when you try to open it by hand, and an automatic garage door opener may no longer be able to lift the door at all.
Center and level the first section after you install the brackets. The door must be level even if the floor isn’t, so use shims under the section to level it. The rubber gasket on the bottom section will fill the gaps created by an unlevel floor. To hold the level in place, tape it to the section. To hold the section in place, lightly toenail a 16d nail into the frame and bend it over the section. Add brackets and rollers before setting them in place and stack one section on top of another, toenailing as you go up.
Does your garage door seem to be jammed? There are several reasons this could have happened. The answer may be simple and easy to fix, or there may be a larger underlying problem with your garage door system that requires an expert to repair. Run through the following list to determine if it's a problem you can fix on your own or if you should call a professional garage door technician to repair it for you.
Just like on a bike sprocket, your cables can sometimes become disengaged. Oftentimes, when a torsion spring breaks, the garage door cable will snap as a result. Sometimes, the cable will cause damage to a vehicle or wall, and if a person happens to be in the way of the cable it can cause serious harm. If you cables have snapped, you should call a professional to help you. See the video above.
9.9 Go to the other side of the garage door and insert the end of the cable into the drum. Rotate the drum until the cable is tight. Slide the drum against the bearing and push the shaft to the right. The marks should line up. If they don't, figure out why and correct the problem. It could be a stuck cable, the garage floor may have shifted, or the vertical angle that helps support the bearing plate may have loosened and shifted. Many garage doors have been installed with a gap between a drum and a bearing plate. The cable drums should always be flush against the race of the bearings.
The garage we take for granted very likely stores thousands of dollars worth of tools and household belongings, not to mention your automobiles. Yet this space is typically rather easy for intruders to penetrate. Garage security can be greatly improved by installing a modern garage door opener that features rotating digital codes, which can foil even the most tech-savvy prowlers.
7.5 Slide both springs out toward the cable drums. This is often the hardest part of the job. You may need to file away swollen shaft, set screw burs, drywall or paint. If the shaft is distorted because the garage door installer overtightened the set screws, file the shaft, insert a bar into the cone and tap the bar with a hammer until the cone passes over the enlarged portion of shaft.
When you know you’re in range and the door still won’t open, check to make sure the antenna is hanging down from the motor inside your garage and nothing is blocking it. Your antenna must be free from any obstruction to clearly receive the signal to open and close the door. Also inspect the antenna for any signs of damage. If it looks like there has been damage to the antenna, you’ll need to call your garage door technician to come out and replace it.
When the car and other important equipment have been taken out, immediately remove the broken springs and replace it. The newly bought springs must be compatible with the door for it to function properly. Never attempt to close it without proper help and precaution and never leave it open if the supports are not stable. Always remember to call the technicians to ensure safety.

If your garage door isn’t operating properly, the torsion springs are likely to blame. If you’re concerned about tackling this project on your own, consider hiring out the job to a professional. Otherwise, replace both the left and right springs at the same time to save yourself from having to do the job twice. Remove the old springs and measure them while they’re relaxed. Only then will you be able to order replacement parts and install the new springs. Replacing your own garage door springs takes only a little time and effort and can save you hundreds of dollars.
We have had many concerns with our garage opener unit both safety issue and sleepless nights. At this time we are pleased that so far the unit is operating as it should.Hopefully we hope the issue of the unit opening by it self at early morning hours is solved. And if this is so, we want to Thank all involve in bring a satisfactory solution to this nightmare.
ryan was way more than early when he showed up. ryan gave me a straight up, not nonsensical "ah..ah..." like someone making up a story to listen to. direct and to the point, like a professional, gave me my options that i could present to the boss. the boss didn;t like the price of the new rollers. but she loves that it doesn't sound like a tank coming home from war. we were completely unprepared for this, so, it's good we got a guy like ryan.

Your dream car is parked in out of the elements, but it's not secure because the garage door won't lock. Most garage doors have two horizontal bars that move out from the center of the door into slots along the side of the door in the door track, effectively locking the door in place. Over time, these bars can shift slightly out of position so that they are no longer correctly aligned with the locking slots. To realign the bars, unscrew the guide brackets on the edges of the door so that they are loose enough to move, and then reposition them so that they smoothly guide the locking bars into the locking slots. Lubricate the lock mechanism with machine oil and you're done.


For example, low headroom garage doors often have cable drums on the outside of the end plate and the torsion springs usually wind down rather than up. They normally have left wind springs mounted on the left side of the spring anchor bracket and right wind springs mounted on the right side of the bracket. The first part on the shaft beyond each torsion spring is the end bearing plate. Just beyond the end bearing plate is the cable drum. On these the cable often runs on the front of the cable drum. The bottom of the cable is attached to a bracket that wraps around the front of and outside the vertical track.
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.
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.
Squealing, screeching, or grinding noises from your garage door are usually indicative of a lack of lubricant or an accumulation of dirt or debris in the tracks. When removing debris, do not use harsh chemicals to clean the tracks. Once the track is clean, coat it with lubricant designed especially for garage doors, if possible. If you do not have access to this special type of lubricant, you can use WD-40 on the tracks and hardware. http://youtube.com/embed/Z_eZc-kh40c
