Dodging a falling door:: Reversing this equation gives us x=gt^2/2 as the fallen distance x for a given time t. How much time would you have to dodge a falling door if the spring were to suddenly break at the top of travel? Let us assume you are 5.5 feet tall, so the door will hit your head after falling 2 feet from its 7.5 foot fully-raised height. This 2-foot fall takes sqrt(2*2/32.2) = 0.35 seconds (350 milliseconds). The quickest human response time is about 200 milliseconds, so even if you are alert to the hazard, this leaves you only about 150 milliseconds to accelerate and move your noggin out of the way. If you are an Olympic gold medalist in the 100 meter dash, you can accelerate (horizontally) about 10 feet/second^2, and your 150 milliseconds of wide-eyed panic will move you all of 10*0.15^2/2 = 0.11 foot = 1.35 inch.
Good response time and service; Question - I googled to find the Sears Garage Door repair phone number. During the conversation, I was unsure if this was "Sears" or a "contractor service" or other service. I had to ask if this repair person was coming from "Sears" or an independent repair. I was concerned until the service man arrived in a sears truck wearing Sears apparel. You might want the process to be more clearly identified as Sears.
GUESS YOU DON’T CARE to reply to my emails, so I'm posting it up here.....

I’m a really handy guy, I repair and maintain nearly everything around the house, I am very mechanically adept, and I am also a highly skilled technical person that runs my own business by trade. I would have and could have repaired the belt myself, but I am traveling for business sooner than I could have ordered a belt, and did the repair….which means, I looked at the belts, I watched all the videos, it’s an EASY repair. I have belts down to a science, I’m really not an armchair DIY repair guy, I’m pretty good……That being said, I also shopped for prices of new belts for at least 30 mins or better, across easily 20-30 different parts and/or repair websites. Why am I telling you this? Because I think Chris, and your labor prices are spot on, and he deserved every cent, and your labor billing is more than fair…..however, I think your charge for the belt is a bunch of crap, it is nearly double of the HIGHEST price I found, which was $20-$25 higher than the average prices I found. Based on that alone, there is no way I could recommend, your otherwise FANTASTIC service, to anybody I know with a straight face. That’s just me being honest, because that’s who I am.
Smartphone Control: Many newer garage door openers allow you to connect the device to your home's Wi-Fi network, according to RW Garage Doors. You then can open and close the door through a smartphone app. In fact, many of these apps will give you an alert on the smartphone when the garage door is open for a certain period. Some opener models even can connect to your existing Smart Home system, incorporating all your appliances on one system.

As noted above, set-screw clamping may have distorted the cross-section of the shaft and made it difficult to slide off all the hardware. With the shaft on the floor, it may be possible to restore enough roundness to proceed, using compensating clamping force to the distorted area via a machinist's vise, an arbor press, a hydraulic shop press, etc., on the shaft body. Burrs and other slight distortions on the shaft can be filed off with a hand file or touched with an abrasive wheel on an angle grinder. At some point, the condition of the shaft may just be degraded enough that it ought to be replaced.
Extension spring systems should always be restrained by a safety cable that runs through the middle of the spring, tying off to a solid point at the rear and front of the horizontal door track. Extension springs represent a hazard to bystanders when a spring, pulley, or cable breaks under tension. Metal parts from extension spring systems can suddenly be launched.
Reduce your monthly energy bill with insulated garage doors. They feature an insulated core made of polystyrene that’s surrounded by a steel cover. This can help you maintain the temperature inside your home no matter if it’s extremely hot or cold outdoors. Insulated garage doors are also known for their quiet operation. Be sure to look at the insulation rating – or R-value – when considering garage doors. The higher the R-value, the better the insulation.
If you haven’t looked at garage doors lately, prepare to be pleasantly surprised. We’ve taken the garage door and made it stylish with designs to complement both classic and contemporary homes while still keeping the functionality you desire. A garage door can represent more than 30% of your home’s curb appeal, which makes choosing the right design especially important – and Home Depot has the widest selection available. With over 1,000 different garage door designs in wood, steel, composite, aluminum and glass, you’re sure to find the perfect style to transform your garage… and your home.
We would definitely recommend Precision to anyone that needs garage door services! We were able to get a service appointment right away! Tom arrived and was very professional and courteous. 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!
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.
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.
The third stage of garage door opener technology uses a frequency spectrum range between 300-400 MHz and rolling code (code hopping) technology to defeat code grabbers. In addition to transmitting a unique identifier for the remote control, a sequence number and an encrypted message are also sent. Although an intruder could still capture the code used to open a garage door, the sequence number immediately expires, so retransmitting the code later would not open the garage door. The encryption makes it extremely difficult for an intruder to forge a message with the next sequence number that would open the door. Some rolling code systems are more involved than others. Because there is a high probability that someone will push the remote's button while not in range and thus advance the sequence number, the receiver does not insist the sequence number increase by exactly one; it will accept a sequence number that falls within a narrow window or two successive sequence numbers in a much wider window. Rolling code technology is also used on car remote controls and with some internet protocols for secure sites.
I backed into my garage door, then my husband tried his hand at fixing it...which only made it worse. The door wouldn't go down and we were leaving town the next day. I called at 9 am on a aturday morning, and Tom called to say he'd be there between 9:45 and 10! He got there just before 10 am and fixed the door in less than 30 minutes. He was very fast, efficient, and knowledgeable. The price was lots lower than I thought it would be. All in all, we were very pleased with the service.

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.
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.
You'll never ask yourself that question again. Just look at your phone to know for sure. Most smart garage door openers will tell you if it's open or shut. They'll send a message every time your garage door is opened or closed too, if you like. Electric garage door openers provide a huge amount of convenience and safety. Imagine you're in a hurry, it's raining out, you pull out of the garage then press the button on your garage door opener remote. The garage door closes, and you didn't have to get out of your car.
