Next, the torsion shaft is reassembled with the new springs, the drums repositioned loosely on the shaft, this whole assembly slid back into the end bearings, and the drum set-screws tightened down. I tightened the set-screws about 1/2 or 3/4 of a turn after contact with the shaft, which provides a good grip, but does not distort the shaft. The drums can be set on their old positions, if they were correctly installed, which is snug up against the end bearings to remove any longitudinal play in the torsion shaft. Now the lift cable can be reattached to the drums, and a slight temporary torque applied to the shaft to keep the cable taut while the first spring is wound. This temporary torque is conveniently applied with a pair of locking pliers clamped on the shaft, positioned such that they hold the torque by pressing lightly against the wall above the door, before you start the spring winding, The locking pliers stay on the torsion shaft until you have finished the spring winding locked down the spring cone(s) with the setscrew(s), and removed the winding bars. Then you simply remove them with the release on the wrench handle. I feel that any job that doesn't require a trick manipulation with either locking pliers or duct tape (or in the ultimate case, both!) is just too boring. My trusty pliers look a trifle rusty ever since I used them to clamp something on my outdoor TV antenna "temporarily" and left them out in the weather for, oh, several years. The white stuff on the drum is paint overspray from the original painting of the garage interior.
Recently another type of opener, known as the jackshaft opener, has become more popular. This style of opener was used frequently on commercial doors but in recent years has been adapted for residential use. This style of opener consists of a motor that attaches to the side of the torsion rod and moves the door up and down by simply spinning the rod. These openers need a few extra components to function safely for residential use. These include a cable tension monitor, to detect when a cable is broken, and a separate locking mechanism to lock the door when it is fully closed. These have the advantage that they free up ceiling space that an ordinary opener and rail would occupy. These also have the disadvantage that the door must have a torsion rod to attach the motor to.
The best garage door openers can be controlled from a remote location through your phone. If you’ve ever left home and had a moment of panic, not knowing if you left the garage door open, this feature can give you peace of mind. The door opener’s built-in Wi-Fi connects directly with your home Wi-Fi router, which allows you to close your garage door from wherever you are through a MyQ smartphone app. The Chamberlain Group opener has this feature – it’s a 1-horsepower garage door opener with extra lifting power for unusually heavy doors of over 500 pounds.
An intermediate stage of the garage door opener market eliminated the DIP switches and used remotes preprogrammed to one out of roughly 3.5 billion unique codes. The receiver would maintain a security list of remotes to which it would respond; the user could easily add the unique remote's code to the list by pressing a button on the garage door opener while activating the remote control. The large number of codes made the brute force try-all-possible-digital-codes attacks infeasible, but the systems were still vulnerable to code grabbers. For user convenience, these systems were also backward compatible with the older DIP switch remote codes, but adding an old technology remote to the security list made the garage door opener vulnerable to a brute force attack to find the DIP switch code. The larger code space approach was an improvement over the fixed DIP switch codes, but was still vulnerable to the replay attack.
Uncentered center bearing plate: The center bearing plate need not actually be in the center. It doesn't much matter where it is, since the purpose of the bracket is to anchor the spring ends. This anchoring must be secure, since all the torsion is held together at that point. On a stud-framed wall, this bracket may be placed over the stud closest to the center rather than exactly at the center of the door opening.
Of course, the best garage door openers offer much more than weather protection. They are quick and convenient when leaving or returning home. They can secure what might otherwise be a weak point of home security. Some can even alert you at work if your garage doors aren't closed properly. The challenge you face is finding the right one – this isn’t a product you can simply try out and return until you find the best fit for your situation.

I was careful not to assume that the previous installation correctly oriented the right- and left-hand springs on the correct sides of the center bearing plate. They could have been installed backwards by an incompetent installer, resulting in them having been wound looser (larger diameter coil) instead of tighter (smaller diameter coil) than when in their relaxed state, and if so I would have corrected them on the new installation. The proper orientation of the springs applies their reaction torque from tighter winding such that it turns the drums to lift the door. Verifying this is a rather simple exercise in mechanical visualization, but does require some care to be certain of correctness. If you were to install the springs backwards, and then start to wind them in the wrong direction, then the torsion bar will start winding the drums backwards, and not holding against the vise pliers, which should be obvious to inspection. Winding a spring backwards also tends to screw the spring off the cones; this error cannot proceed too far before the spring slips off the cones.
Many garage door opener remote controls use fixed-code encoding which use DIP switches or soldering to do the address pins coding process, and they usually use pt2262/pt2272 or compatible ICs. For these fixed-code garage door opener remotes, one can easily clone the existing remote using a self-learning remote control duplicator (copy remote) which can make a copy of the remote using face-to-face copying.
Right-hand versus left-hand winding: Springs are chiral, that is, wound or "laid" in either a left- or right-hand orientation. This is a critical property of their design and specification; you cannot substitute a left for a right or vice versa. If you were to grasp the spring in your hand, and if your right hand orients the tips of your fingers like the ends of the coiled wire when your thumb points "out" of the core of the spring, then you have a right-hand spring; likewise left (which end you grasp does not matter). (This also happens to match the "right hand rule" of magnetic polarity, if you happen to be knowledgeable in such esoteric subjects.) Another way to identify the winding is to examine the spring vertically in front of you; if the coils facing you rise going to the right, it is right-hand (thus you can remember, "rise to the right is right-hand"), and likewise left indicates left-hand. Another way is to view the coil axially; a right-hand spring winds in a clockwise direction as it recedes away, and a left-hand spring counter-clockwise. Yet another way, not so easy to remember, is to hold the spring vertically and compare the coil shape to the letter "Z" (indicates right-hand lay) or the letter "S" (indicates left-hand lay).
Using your drill, add tension to the torsion spring. This system uses a single spring for a double door, but many manufacturers use two springs for a double door. The painted line on the spring acts as a gauge for the number of turns you put on the spring. To keep the bar from turning while you’re adding tension, attach a locking pliers to the bar on both ends of the spring. Apply lubricant for garage doors to the spring.
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.

Luckily, your garage door is a pretty sound investment. According to Garage Wow Now, garage doors were ranked in the top three for home improvements whose costs are recouped through increased home value. Similarly, realtors regularly increased the list price of a home with a new garage door by 1 to 4 percent! That means, if you spend $2000 on a new garage door, you can increase the value of your home by almost $8000 if you have a $200,000 home. Furthermore, compared with the other two highest rated improvements — siding replacement and deck installation — a garage door replacement is far more affordable.
If your garage door's spring breaks, stops working properly, or snaps, you'll lose the ability to open and close your garage door. This could happen due to a variety of issues, like normal wear and tear or from extreme temperature changes in a short amount of time. Spring replacements require a quick response from a garage door provider near you. Contact The Home Depot and a local, background-checked technician will respond within 24 hours.

The typical electric garage door opener consists of a power unit that contains the electric motor. The power unit attaches to a track. A trolley connected to an arm that attaches to the top of the garage door slides back and forth on the track, thus opening and closing the garage door. The trolley is pulled along the track by a chain, belt, or screw that turns when the motor is operated. A quick-release mechanism is attached to the trolley to allow the garage door to be disconnected from the opener for manual operation during a power failure or in case of emergency. Limit switches on the power unit control the distance the garage door opens and closes once the motor receives a signal from the remote control or wall push button to operate the door.[3]


Some of the best garage door openers offer special features like a backup power source or a timer that automatically closes the door behind you at a predetermined time. While the door openers we reviewed vary in terms of power, noise and efficiency, they are all effective in the all-important task of letting you come and go with the simple push of a button. Here are the criteria we used to rank the top garage door openers:
The Lifestyle garage door screen is a fully retractable garage screen door that works with your existing garage door. The Lifestyle features an industry first, fully retractable passage door for ease of entry and exit without having to retract the entire system. The Lifestyle garage screen is fully spring loaded, making opening and closing quick and easy.

With garage door installation costs, these numbers also include the actual purchase of the new door and other hardware, including the tracks, adhesives, connectors and fasteners. Keep in mind that if these numbers seem extreme, garage door replacement and upgrades can yield, on average, one of the highest returns on investments for homeowners — with an expected 85 percent.

As we’ve mentioned before, springs are installed within your garage lift mechanism in order to help lift the door. Because doors are so heavy, the lift motor would undergo far more significant wear and tear if it had to lift the full weight of the door every time you opened it. Furthermore, in order to ensure that you can open your door even if you lose power in your home, springs allow you to lift the door by hand when the motor is disengaged.
Having a mismatched pair makes it difficult to specify the correct matched-pair replacements. To obtain replacement springs for a mismatched pair, you can either specify the same odd pair, try to calculate the equivalent matched pair sizes, or (this is the best method:) measure an accurate door weight and calculate the right spring size(s) "from scratch". The spring seller should be able to do the calculations from your accurate measurements of weight, height, and drum size; or you can attempt the calculations yourself using my engineering formulas below.
The first garage door opener remote controls were simple and consisted of a simple transmitter (the remote) and receiver which controlled the opener mechanism. The transmitter would transmit on a designated frequency; the receiver would listen for the radio signal, then open or close the garage, depending on the door position. The basic concept of this can be traced back to World War II. This type of system was used to detonate remote bombs. While novel at the time, the technology ran its course when garage door openers became popular. While the garage door remote control transmitter is low power and has limited range, its signal can be received by other, nearby, garage door openers. When two neighbors had garage door openers, then opening one garage door might open the neighbor’s garage door as well.

The second stage of the wireless garage door opener system solved the opening-the-neighbor's-garage-door problem. The remote controls on these systems transmitted a digital code, and the receiver in the garage responded only to that code. The codes were typically set by eight to twelve DIP switches on the receiver and transmitter, so they allowed for 28 = 256 to 212 = 4,096 different codes. As long as neighbors used different codes, they would not open each other's garage doors. The intent of these systems was to avoid interference with nearby garage doors; the systems were not designed with security in mind. Intruders were able to defeat the security of these systems and gain entry to the garage and the house. The number of codes was small enough that even an unsophisticated intruder with a compatible remote control transmitter could just start transmitting all possible codes until he found one that opened the door. More sophisticated intruders could acquire a black box master key that automatically transmitted every possible code in a short time. An even more sophisticated method is known as a replay attack. The attacker would use a code grabber, which has a receiver that captures the remote's digital code and can retransmit that digital code at a later time. The attacker with a code grabber would wait nearby for the homeowner to use his remote, capture the code, and then replay the code to open the door when the homeowner was gone. Multicode openers became unpopular in areas where security was important, but due to their ease of programming, such openers are often used to operate such things as the gates in gated apartment complexes.
Although the door weight and drum size determine the maximum torque (termed MIP, maximum inch-pounds) needed from the fully-wound spring(s), the spring selection for a given door can still be varied to adjust the cycling stresses. A heavier wire on a larger diameter or longer length will produce the same torque as a lighter wire on a smaller diameter or shorter length, while undergoing less stress and therefore increasing expected cycle lifetime. The heavier spring will cost more but last longer, so this is another design trade-off. Calculating these spring sizes in the field is done using a book of tables (or the software equivalent) that we cannot provide here, although you will find the formulas to estimate spring properties below. If you can accurately provide the weight of the door, or the size(s) of the old spring(s) (assuming they were well-matched to balance the door), then a spring dealer should be able to tell you which spring sizes will work for you.
Whether you're planning on moving in the future or you're fixing up your forever home, replacing a garage door can provide an excellent return on investment and boost your home's resale value. According to Remodeling magazine's 2016 Cost vs. Value report, garage door upgrades provide a nationwide average return on investment of over 90%, making it one of the top five home improvement projects.
When you install a new garage door, replace all the hardware as well. If your automatic opener doesn’t have an automatic reversing system that includes photoelectric eyes, replace it. Doors with openers also require two extra pieces of hardware that you’ll see in Photo 4: a support strut (usually included in the door kit) and an opener bracket (not included). For doors with torsion springs located over the door, spend the $50 or so to have a garage door professional release the tension.
Before purchasing a roll-up door, measure the space between the top of the garage door opening and the ceiling or overhead framing. Standard tracks require headroom of about 14 inches. If you don’t have that, you can get low-headroom track, which costs about $100 more. There are also tracks specially made for garages with unusually high walls or cathedral ceilings.

When ordering springs, be aware that a number of different sizes of springs will make proper replacements, not just the specific size being replaced. The wire size, winding diameter, and length can be traded off to make springs of varied geometry but equivalent torque characteristics. This will also affect the expected lifetime (in cycles) for the spring(s). Since the critical specification for a replacement is the weight it is designed to bear, not the sizes per se, there are likely several stock sizes that replace a given old spring. The spring distributor's inventory may happen to offer only a different size with an equivalent weight-bearing specification. One has to judge whether to trust the advice of the seller in such situations. The seller should have the data to know what substitutions are proper.


Technician gave me a window of 1-4pm, I called at 330 to see if he was on his way. He told me he would be there at 4pm, reason being was because of the amount of work orders he had that day. He was also by himself, had no helper. I was very satisfied that he was able to repair my garage door. He was very professional considering he showed up on a Friday afternoon on a 100 degree day. Thanks again
