In the photo, you can see an extra lag screw on the bottom of the plate, reinforcing weak anchoring from the original two screws (hidden behind the springs). This extra screw was applied by a professional garage door technician on a previous repair visit. I have since replaced the backing with a sound plywood panel anchored into the concrete door header. Since these bolts clamp all the opposing torsion to the wall, the attachment must be sturdy.

My garage door broke on a Saturday night as I was getting ready to leave for a holiday party. Kelvin was here within 30 minutes. He reviewed everything with me that was happening with my door. He gave me the estimates of what was immediately needed to be done in order for my door to raise and then what I will need to have done very soon. I could see all the problems he pointed out to me and I decided to have everything done. He completed everything that night. I was very satisfied with Kelvin’s professionalism and the work he did. Thank you again.

To estimate the maximum physical force required to wind these springs, consider that they are balancing the weight of the door with a torque applied to a lift drum on each end of the torsion shaft. The lift drums have a 2-inch radius, which is the standard residential size, and corresponds conveniently to about a 1-foot circumference. If we pessimistically assume the 10-by-7-foot door has a weight of 350 pounds, this implies a torque of 350 pounds on a 2-inch radius, that is, 700 inch-pounds, or 58 foot-pounds. Each of the two springs should be exerting slightly less than half of the balancing torque, or 29 foot-pounds. Compare this to, say, the bolts in an automobile, which are typically torqued to values of about 50 foot-pounds, or tire lug nuts, which may be torqued to well over 100 foot-pounds.
The prior clamping of the set-screws tends to have pressed a dimple into the hollow shaft and to have distorted the shaft's roundness into an eccentric shape. While releasing the set-screws, I was careful to loosen them enough to let the cone swing around any such distortions. I was also careful to observe any binding of the old cones on the eccentricity or burring on the shaft. The fit of the cone on the shaft is supposed to be loose enough to avoid binding, but if it were to occur one would have to be careful not to assume the spring was unwound when in fact the cone was just stuck on the shaft. If I had a stuck cone that I could not unwind with a little extra force, then I would have called in a technician to deal with it. In the worst case, I suppose the spring must be deliberately broken with some hazard, thus releasing it for a forceful disassembly, and the shaft and some other parts replaced. But this is an unlikely situation and in this case was not necessary.
We lead busy and sometimes hectic lives. It's easy for someone low on sleep and high on stress to accidently bump into their garage door leaving a little damage. If you're lucky it's just an individual garage door panel that's been damaged. This will leave you with the option of garage door panel replacment. There's a chance it might cost you upwards of $150-200 to spot repair damaged garage door panel. If it happens to be an in-production model, they probably will be able to repair or replace the entire panel (if needed) for $250-400. Unfortunately if you've got an older model of garage door the panels may no longer be in production. This might seem like a disadvantage because you'll end up having to just replace the entire door. Many times it's actually easier and more cost effective to just replace the garage door.
While winding or unwinding, one must be mindful of the possibility that the spring could break during winding process itself. If that should happen while the spring is significantly torqued, hazardous forces on the winding bar will suddenly become unbalanced, and the bar will take an unexpected jump, possibly injuring your hand or anything else in its path. At the same time, the spring remnants, although captured on the torsion bar, will create a frightening racket that would give the bravest soul a start. So your winding technique should be firmly in control of the rods, and you should not be so delicately perched on a ladder such that a startle will result in a fall.

The torsion shaft with lift drums on the ends is above the door. The standard residential door shaft is a 1-inch outside diameter hollow steel tube. The inside diameters of the bearings, drums, and winding cones are sized to loosely fit that 1-inch diameter shaft. At the center is a bearing plate, on either side of which are the torsion springs, or in some cases just one larger spring. The spring pictured on the left in the photo is broken about 1/4 of the way in from its left end. The black shaft with dangling rope and door bracket is the track for the electric opener.
Electric Garage Door Openers – Service and repair of the electric garage door opener itself, including the lift mechanism that pulls the door up and guides it down. This is typically not part of the garage door itself and is serviced and repaired on its own interval. Typical service includes inspection, repair, adjustment, and lubrication if needed. Also, we typically inspect the mounting of the unit as well as its attachment to the door itself.

A knowledgeable installer with good inventory can offer you upgraded spring lifetimes by using longer, heavier springs than were originally installed. For example, you may be offered more expensive springs with expected lifetimes of 15, 25, or even 100 thousand cycles, instead of the standard 10 thousand. The difference in labor to substitute this upgrade is nil. Since the dealer's cost of springs is proportional to weight, and typically a small part of the job price anyway, the dealer's cost for this upgrade is slight. This would seem to be a excellent option to offer every customer, and if correctly calculated and reasonably priced, one that you should take as cost-effective. Yet you may not be offered such an upgrade, if the installer is not adept at making the rather simple calculations, or if the optional springs are not on his truck, or if you're not around to be asked, or if the installer just doesn't like selling or taking time to discuss such details.

Spending your whole weekend setting up a new garage door opener is not on the top of most peoples list. This opener is easy to install for most levels of DIYers and it provides a quiet and reliable open and close. This has 3/4 HPc DC chain features and the powerhead can open 12" in a second. It has a wireless remote and Intellicode 2 security to prevent people from breaking into your home. 
The majority of those who have purchased this product have been happy with it, saying it’s extremely quiet and comes with a great lifetime warranty. Some of the more critical reviews had to do with the remote not working well and other minor malfunctions. (A few quick tips can help you fix any common garage door opener problems.) However, most were satisfied with the product and would recommend it to others. 
The deluxe-model upsell trick: Don't you want the best? Don't you want to protect your family? Galvanized springs may be offered to you at extra expense as "longer lasting". Although bare springs (also called "oil tempered") can develop a light film of rust, the eventual failure is due to fatigue and not corrosion. The use of coated springs (whether galvanized, painted, powder-coated, or surface-converted) is mostly about appearance: the customer likes his new door to look shiny, and the customer doesn't like repair parts that show superficial rust from storage.

Step 2: Check the tracks with a level to make sure they're properly aligned. Horizontal tracks should slant slightly down toward the back of the garage; with roll-up doors, the vertical sections of track should be exactly plumb. Both tracks must be at the same height on the garage walls. If the tracks are not properly aligned, loosen but do not remove the screws or bolts that hold the mounting brackets, and tap the tracks carefully into position. Recheck the tracks with the level to make sure they're in the right position; then tighten the screws or bolts at the mounting brackets.


Note that I am measuring a spring that is fully relaxed because it is broken!. The length of the relaxed, unbroken spring is the specification of interest. It is harder to measure unbroken springs on an intact door because the springs should not fully unwind, even at the top-of-travel. If you can't be certain of the spring diameter from indications on the cones, then you have to go through an unwinding procedure to relax them fully for measurement, or perhaps reckon the size from measuring the somewhat smaller diameter at the nearly unwound condition when the door is at its top-of-travel (although one should not attempt to raise a door with a broken spring).

The replacement springs in my case proved to be 0.2253 wire size, 2.0 inch (inside) diameter, and 24 inches long, in a pair of one left- and one right-hand winding. Actually, the old springs in these pictures were a slightly smaller size, but another similar door on this garage was better balanced by that size. Whoever installed the old springs didn't quite get the weight and size just right; it is not unusual to find a repair service installing a slightly off-balance spring size that happened to already be on the truck during the service call. My electric opener had no trouble handling the small imbalance. But since it is safer to reduce the electric operating force as much as possible through careful balancing, I chose the size that was working better on the other door. The Chamberlain brand electric openers (also sold by Sears) I have incorporate a plastic worm gear that tends to wear out after some years of use, requiring a disassembly and installation of a $20 repair kit; this wear is minimized by a properly balanced door.
Garage remotes work by sending a coded signal via radio frequency to the garage door opener. If this code matches that of the opener, then the motor will operate and raise or lower the door. Older devices use a single coded switch, whereas newer systems utilise a rolling code that changes each time the remote is used, increasing the security of the door by offering billions of combinations.
Single panel doors are constructed from one monolithic panel. From the closed position a single panel door swings up and overhead with a hinge on each side (known as jamb type hardware) to the fully open position. A disadvantage of monolithic panel doors is that the swing up arc of the door occurs partially outside the garage. This means a vehicle must stop and park several feet in front of the door to avoid being hit by the garage door when it is opened.
Critical measurements: Torsion springs come a variety of standardized sizes, so you have to carefully measure the old springs to know what to order for proper replacements. Tables of standard sizes and designs are on the Web, such as here [www.industrialspring.com]. The four critical measurements (all in inches) are: (1) the wire thickness (which I'm measuring here with a dial caliper; you can also measure the length of a number of closely stacked turns with a ruler and divide by the number of turns in the stack, measuring 10 turns this way makes the math easy), (2) the inside diameter (not outside!) of the relaxed (not wound!) coil, (3) the overall length of the relaxed (not wound!) spring coils, not including the winding cones, and (4) the right- or left-hand winding of the spring. One must glibly quote those figures to the spring supplier, otherwise one's lack of expertise will be obvious, and one will not be worthy of buying the parts.
The most common grade of torsion springs have an expected life of about 10,000 cycles. The hardened and tempered steel experiences tremendous forces each time the door opens or closes. Gradually, the steel fatigues with each flexure, and eventually cracks and breaks, usually releasing its stored energy in an instant with a horrific "sproing" noise or bang. If you average about two car trips per day, opening and closing the door a total of 4 times daily when you come and go, then that expected life becomes 2500 days, or only about 7 years. If you have an automatic opener, then if you're like me, you tend to cycle the door even more frequently, and can expect the need for spring replacement even sooner. Moreover, my three-car garage has three doors, so on average I can expect a repair job every few years. Over a lifetime, it is very economical to do these repairs myself.

If the wires that run from your opener to the photo eyes and to the wall button are exposed, replace them, too. Those wires have probably been in your garage for 10 years or more, and they may be nicked or worn. Newer openers are extremely sensitive and won’t work if a wire is damaged. It only takes about 15 minutes to run the new wire, so it’s time well spent. If the wires are protected inside the wall, you don’t need to run new wire.
Single panel doors can also be installed with (one piece track type hardware) that folds the door back with a single horizontal track on each side (which is mounted at the top of the wood frame) and a roller, (mounted to the top of the door on each side. A hinge on each side that attaches to the bottom of each side of garage door. Using track hardware, a car can be parked much closer to the door, as the whole door, when in the open position, rests completely inside of the garage door header. Track type hardware has much less arc when raising and lowering the garage door as opposed jamb type hardware.[citation needed]
We’ve been reviewing the best garage door openers for more than half a decade. This year we chose the Chamberlain Premium as our top pick. It’s an efficient, reliable garage door opener, and it comes with a backup battery system that works in a power outage. This model also has a preinstalled timer that closes your garage door automatically so you don't have to worry about whether you left the garage door open.
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.
As in an elevator, the electric motor does not provide most of the power to move a heavy garage door. Instead, most of door's weight is offset by the counterbalance springs attached to the door. (Even manually operated garage doors have counterbalances; otherwise they would be too heavy for a person to open or close them.) In a typical design, torsion springs apply torque to a shaft, and that shaft applies a force to the garage door via steel counterbalance cables. The electric opener provides only a small amount of force to control how far the door opens and closes. In most cases, the garage door opener also holds the door closed in place of a lock.
We were very pleased with the service we received. The receptionist that took our information over the phone was courteous and efficient. The young man, Nate, who came to the house was on time, respectful of our wants and needs, and very knowledgeable about the job. He was able to fix our door easily. Finally we have a garage door that works with a push of the button! We highly recommend this company for your garage door needs.read more
One might stack lumber or arrange some other low platform for a steady footing, instead of the ladder. The aluminum ladder shown here is the splendid 16-foot Krause Multimatic, which carries a Type 1A Industrial rating (300 pound working load); I highly recommend it. However, product liability apparently forced this company into bankruptcy in September 2000 and the company ceased operations in June 2001; see http://www.krauseladders.com (this Web site went dead sometime in mid-2002). The world is a dangerous place.
Now 13 pounds of force must be respected when backed by many hundreds of foot-pounds of stored energy, waiting to be released. Holding this torque is equivalent to stalling a 3 horsepower DC motor. But holding and turning these handles does not require extraordinary human strength. Note that this maximum tangential force depends only on the weight of the door, and the radius of the drums, and is divided by the number of springs (some designs have only one longer spring, as mine did originally, instead of two shorter ones). Higher or lower lift distances imply more or less turns to wind the spring (and thus a different spring geometry), but not more force on each turn.

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.
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.

If this manipulative, we-are-your-nanny business approach is truly in our best interests as consumers, then we shouldn't be allowed near ladders, lawn mowers, or power tools. Those products are just as hazardous and prone to misuse as torsion springs, yet no one thinks of them as forbidden. The only genuine difference is that torsion springs are a hazardous thing you need only rarely, while a lawn mower is a hazardous thing you need all the time.

Stress and lifetime: Calculating the maximal stress in the wire is useful for estimating the lifetime. Using the formula above, the bending stress S in the spring wire is 32*238/(π*0.2253^3) = 212 Kpsi. The spring index C is D/d = 2.23 / 0.225 = 9.88. The Wahl correction factor is Kw = (4C-1)/(4C-4) + 0.615/C = 1.15. The Wahl-corrected stress is Kw * S = 1.15 * 212 Kpsi = 244 Kpsi. This predicts about a 10,000-cycle lifetime, which is the standard "cheap spring" configuration originally installed. Note that while this stress is proportional to the torque being applied, it is also in proportion to the inverse third-power of the wire size. Thus slightly heavier wire sizes (and suitably adjusted D and/or L) radically improve the expected cycle lifetime of the spring.
