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.
Screw-drive garage door openers aren't as popular as some other types, but feedback indicates that those that give the Genie Excelerator a try are largely very happy that they did. It's a fast performer, owners say, and the company claims that it can move a door at a rate of up to a foot per second. It's relatively quiet, too -- perhaps not the absolute quietest that you can buy, but certainly quieter than a chain-drive opener, and quieter than older screw-drive openers, users report.
Measurements: With the door in the down position, I measure a wire size of 0.273 inches, outside diameter of 2.0 inches, and overall length of 41.5 inches. Relaxing the spring shortens the length by about 7.5 coils of wire, so to estimate the relaxed length, we deduct the wire diamter of 0.273 inches times 7.5 from the 41.5 inch wound length, yielding an estimated relaxed length of 39.5 inches. The mean coil diameter is 2.0 - 0.273, or 1.73 inches. Perhaps this was actually a 40-inch-long spring with a 1.5 ID, 1.75 mean diameter, and 2.0 OD, but let's continue on calculating with the actually observed sizes. The number of coils in the relaxed spring is the relaxed length of 39.5 inches divided by the wire size of 0.273 inches, or about 145 coils. Deducting about 5 dead coils at the ends yields 140 active coils.
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.
Location, climate and building codes are just a few factors to consider when determining which type of garage door is right for your home. Depending on the region you live in, you may need to choose a wind load option for your garage door. Wind loaded garage doors help safeguard your home in high wind prone areas. With garage doors serving as the largest and often times the primary entrance to the home, an insulated garage door may also be right for you.
If you’re replacing an existing garage door opener in your home, the simplest method for finding the right horsepower is to check the rating of the unit in your garage and get something with equal or higher power. Most homes have single- and double-car sectional garage doors made of aluminum or steel, which is the most affordable type of garage door. These doors are relatively light, so a motor with rating of 1/2 horsepower is more than sufficient. While 1/3 horsepower motors are available, they can wear out faster than those with 1/2 horsepower in such settings, so it’s a good idea to invest a little extra for a more capable garage door opener.
Great! We specialize in all sorts of garage door repair work. Working around the garage door can be fairly dangerous if you’re trying to repair this issue on your own. Most garage door companies will quickly remind folks about this, and it’s true. Their are some hazards to watch out for when working around these heavy and high tension doors. We recommend you give an expert a call to address the issue in a safe and timely manner for you.
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.

The Genie SilentMax 750 belt drive garage door opener isn't as feature-packed as the Chamberlain B970, but its value is hard to overlook. The 75-HPc motor isn't as strong as the B970s, but is still plenty strong for any residential use, and the opener is widely judged to be pleasingly quiet. Smart features are built in, too, but using those requires the addition of the optional Genie Aladdin Connect module (Est. $95). The biggest downside is that there's no battery back-up.
With the rods and other tools at hand, I am ready to begin. The first task is to remove the broken spring and its unbroken mate from the torsion shaft. To remove and disassemble the shaft and lift drums, the torsion on the unbroken spring must first be released. I used a ratcheting box-end wrench to loosen the set-screws while pushing the rod against the force I knew would be released when the screws let go. Later I switched to an open-end wrench for the set-screws, since some of the square screw heads were too rough to fit in the box-end wrench.
Spring stretch: When the door is at the top of travel, the spring(s) are hardly wound, but are stretched, so on a single-spring installation this stretch tends to pull the shaft towards the non-spring side. With two springs, the stretch tends to cancel out. This top-of-travel spring stretch, being about 7 or 8 turns of the wire, will thus amount to upwards of about 2 inches on a typical size spring of 0.253 wire. This spreads out to a gap of about 0.020" per coil on a typical 100-coil spring, so the stretch is not very visible.
Your ad had no cheap coupons or promises.. Just business. Service was more than prompt. No attempt to fix something that was not broke or did not try to sell me anything I did not need. He stated the price at the beginning and stuck to it. (I was so pleased, I did not bother to mention a senior discount.) Very, very pleased that I have found someone I can trust and rely on.
