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.

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.

Install the vertical roller tracks first by wrapping the curved lip around the rollers. The top of these tracks should be approximately 8 in. below the top of the top section. Wait to install the upper tracks until this step is complete. Check the level of the top section to make sure the tops of the vertical roller tracks are level with each other. The bottom of the roller tracks should be at least 1/8 in. off the concrete floor. After leveling and mounting these tracks, install the upper roller (horizontal) tracks.

He took the time to go over what repairs were needed and provided an estimate. He was ready to do the repairs right then and there and within a few hours, we had our garage door up and running like new! Thanks to Tom and Precision for a positive experience!
At first glance, there appears to be a wide variety of garage door opener brands, but a closer look reveals that most openers are made by just a handful of companies. For example, Chamberlain garage door openers are well regarded in their own right, but the company also makes garage door openers for Craftsman and LiftMaster. Likewise, the Overhead Door Co. manufactures Genie garage door openers in addition to its own brand.

The German-made, .75-horsepower (equivalent) Direct Drive 1042V004 garage door opener doesn't use a belt drive or a chain drive. Instead, the mobile motor crawls along a stationary chain, making it exceptionally quiet. This garage door opener is also feature-packed, though the wireless entry keypad is an extra-cost accessory. Reliability is excellent, and installation is at least a little easier than some other garage door openers. This opener is also sold under the Sommer brand and with different model numbers, but all are similar.
Removing winding cones from an old broken spring for reuse in a new spring: Springs without the winding cones installed are a little cheaper than with the cones. Twisting the old cones into a new spring is easy with a vise and pipe wrench, but it can be tricky removing old cones from a broken spring for reuse. To remove old cones, mount the cone in a vise such that the spring portion is free. Grab the last few turns of the spring in a pipe wrench, engaging the teeth of the wrench into the end of the spring wire. Turn the wrench against the end of the spring wire, releasing the end of the spring from its clamping onto the cone, as you twist the loosened spring off the cone. Another more certain if not brutal method is to use an angle grinder with a thin metal-cutting disk to cut through the loops of spring wire where the loops wrap around the cones, being careful not to nick the cone itself too much. You could also cut into the old spring loops with a just hacksaw and break off the loops with hand tools, but this will require a lot of effort.
Since the springs are winding "up" when the door is closing and going down, the fully closed position is the most stressful on the steel and thus the most likely position at the moment of failure. This is a good thing, because failure near the top-of-travel means that you suddenly have a large, increasing weight falling. Thus we see the principle that you should never be standing or walking under the door when it is opening or closing, especially if you do so manually instead of with an electric opener. When the springs are working correctly, the door appears nearly weightless, but this is an illusion that turns into a calamity when the springs suddenly fail.

In my case, removing and replacing the relaxed springs required that I take down the assembly: torsion shaft, lift drums, and bearings. Doing that requires unbolting the center bearing plate from the wall, removing the drums from the shaft, and finally sliding the shaft back and forth out of the end bearings to remove the whole assembly off the wall. I am fortunate to have a lot of clearance in this garage to make the disassembly simpler. Tighter clearance to walls or ceiling would make disassembly a more difficult manipulation.
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.

Once the shaft, springs, and center bearing plate come down and lay on the floor, the old springs should be easy to get off and new ones slid on and assembled. Two bolts hold the center cones to the center bearing plate. The bearing on the center plate can be oiled while it is exposed from having the springs off. At this point it is a relief to be working with inert parts while standing on the floor rather than energized parts while up on the ladder. You might think it would save a little time to replace the spring with the shaft left up on the wall, but I found it was easier and safer to lower the works down to the garage floor first.
Trading wire size for length, diameter, or cycle life: Now we are really going to save you some money, if you just recall your high school algebra class (and I don't mean that cute cheerleader who sat next to you). If you further understand the role of the 4th power of the spring wire size (letter d in the formulas above) in the numerator of the spring rate formula, and how to increase or decrease d to compensate for changes in length, diameter, and cycle life, then you're qualified for elite spring calculations. Matching springs is a matter of equating the 4th power of the proportion in wire size change to the proportion of change in the diameter or length or the product of both diameter and length. However, it is usually best to only increase wire size when substituting a spring, since this does not derate the cycle life. If you observe that the formula for bending stress is proportionate to the inverse 3rd power of the diameter, then physically a proportionate increase in wire size will result in a dramatic increase in cycle life of the 3rd power of that proportion. Trade-off example: Yawn with me while we ponder my original spring once more. Let's say I was in a fit of engineering mania, and wanted to replace my spring having a 0.2253 inch diameter wire (d = 0.2253) with a 0.262 wire version (d = 0.262). How much longer is the spring with equal torque rate, assuming we use the same coil diameter? The proportion of this change is 0.262/0.2253 = 1.163, and the 4th power of that is 1.83. This means the length must increase by a factor of 1.83 (again, not counting dead coils). Recalling that the length in Example 1 was 102 non-dead coils, the heavier wire spring must be about 1.83*102 = 187 coils, which when adding 5 dead coils and multiplying by the wire size to get the overall length, is (187+5)*0.262 = 50 inches, versus 24 inches in the original. So using this heavier wire more than doubles the length (and thus the mass and thus the cost). While the cost about doubles, the stress goes down by the inverse 3rd power of the wire size proportion, or 1/(1.163**3) = 0.64. Sress is favorably, non-linearly related to cycle lifetime (halving the stress more than doubles the lifetime), so this decreased stress should more than double the expected lifetime of the spring. While the up-front cost is more, the true cost of an amortized lifetime is much less. In short, per cycle it is cheaper. Ah, the wonders of engineering calculations! Conclusion: Observe that the stress formula (and thus the cycle lifetime) depends only on wire diameter (d) for equal torques. Thus the only way to improve cycle lifetime is to use heavier wire. For equal torques, heavier wire size, due to the exponents in the formulas, increases cycle lifetime much faster than it increases mass (and thus cost), physically speaking.

One can overwind the springs slightly, up to about 8 turns on a standard residential door (that is, 1/2 or 3/4 extra turns), to compensate for undersized or fatigued springs, or increased door weight from painting or humidity, but this results in more stress on the springs and therefore decreased lifetime. If the door is too heavy for that slight tweak, then different springs are needed.

If you have an oversized door, one made of a heavier material such as wood, or a one-piece door, you should consider getting something stronger. In these cases, look for a garage door opener motor rated between 3/4 horsepower and 2 horsepower. There’s nothing stopping you from using a 2-horsepower opener on a smaller door, which can make for smoother operation and a longer service life, but high-horsepower units cost more.

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.

Another moment of truth arrives as the winding-up of the springs begins. (I am just posing here with the camera held out in my left hand. Except for lifting the door onto the scale, this was a one-man job, including the photography.) The position of the bars in this photo was necessary to take the photo, and does not show a correct winding technique, You should not have to swing the bar up as high over the top as shown. The lower bar during winding should swing from pointing down to pointing a little past horizontal. Then you hold that bar horizontal while socketing the other bar pointing down, apply force to that (now) lower bar, then remove the (now) upper bar, wind one-quarter turn, and repeat.

You can choose from three basic types of steel door: (1) steel only; (2) steel with insulation on the inside; and (3) steel on both sides with 1-3/8 to 2 in. of insulation. Other features that add to the cost are thicker insulation and windows, especially insulated windows. The do-it-yourself tensioning systems also add a little to the door’s cost. Be sure to specify exactly what you want.

In 1992 the United States Consumer Product Safety Commission released new rules for automatic garage door openers. Anything manufactured after 1993 was required to include either an electric eye (a pair of sensors that detect an object obstructing the doorway) or a wall-mounted control button that users hold down in order to close the door entirely. Most manufacturers opted for the electric eye method, sometimes referred to as safety sensors.

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.
Once the springs are torqued, the setscrews tightened, and the locking pliers and winding rods removed, do not play with turning the torsion bar using the winding rods. Doing so even momentarily can relieve the tension on the lift cables, which then easily slip off the drums. Replacing the cables on the drums can be difficult without repeating the entire spring unwinding-winding procedure again, and the cables can be damaged if tension is applied while they are off the drums.
The standard winding tools are simply a pair of 18-inch lengths of mild steel rod, 1/2-inch diameter. Winding cones can have different socket sizes (such as 5/8 inch instead of 1/2 inch), so it is important to measure the socket and select a matching rod diameter. Also beware that poor-quality cones may have a sloppy fit to the winding bars, and a loose fit presents a severe hazard of slipping at the worst moment; anything more than about an inch or two of play at the handle end is too loose for safety. I bought a 3-foot length of zinc-plated 1/2-inch diameter steel rod from Home Depot for about $3, which conveniently cuts into two halves of just the right length (the store might even cut it for you if you ask). A steel supplier selling at commodity prices might charge about 50 cents or so for such a piece that weighs about 2 lbs. Drill rod would work if used in the annealed condition in which it is originally sold, but the added expense provides no benefit and the brittleness (if it had been hardened and not annealed) would worry me a bit. Rebar, threaded rod, screwdrivers, etc., are absolutely foolish as they will not fit the socket snugly. Aluminum rod is definitely too weak, and will bend under the torque that must be applied. Longer rods would make for more leverage but unwieldly swing; shorter rods make for uncontrollable swing. As we'll calculate below, the 18-inch standard tool length is an appropriate compromise. Note that you do not need 18 inches of ceiling clearance above the torsion shaft to use an 18-inch rod, since you need not swing the rods above horizontal when winding.
This page is a description of how I replaced torsion springs on a garage door. You may find that my experience either frightens you from trying such a stunt yourself, or encourages you to give it a try. You may curse me for revealing the techniques supposedly known only to the trade, or perhaps thank me for explaining how it's done. All the secrets are revealed below. Even if you hire this work out, just knowing how it is done will help you shop for the best deal and avoid falling prey to overcharging tricks.
Another recent innovation in the garage door opener is a fingerprint-based wireless keypad. This unit attaches to the outside of the garage door on the jamb and allows users to open and close their doors with the press of a finger, rather than creating a personal identification number (PIN). This is especially helpful for families with children who may forget a code and are latchkey kids.

In the United States, the Consumer Product Safety Improvement Act of 1990 required that automatic residential garage door operators manufactured on or after 1 January 1991 conform to the entrapment protection requirements of the 1988 version of ANSI/UL standard 325.[11] A requirement for redundant entrapment-prevention devices was added in 1993; such a system can use an electric eye, a door edge sensor, or any other device that provides equivalent protection by reversing the travel of the closing door if an object is detected in its path. [12][13]
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.

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.

With over 300 independently moving parts, your garage door is a deceptively complex piece of equipment. To help prevent malfunctions and break-downs, it is a good idea to occasionally perform a garage door tune-up to keep all of these parts in good working order. A regular tune-up service by a Sears professional can prevent unexpected door problems and prolong the life of your existing equipment.
