Given the complexity of a garage door and opener system, there are a variety of different areas something could go wrong. If your garage door shakes or is very loud during operation, the garage door closes all the way only to immediately open back up, the garage door opens slowly or closes too quickly, or the garage door opener and remote aren't working at all, you should seek help from a professional garage door repair specialist.

(The Wahl correction factor accounts for additional stress in the material due to shear forces, although these forces do not contribute to the spring's torque. These shear forces become significant in designs using a low spring index, which is to say, a relatively thick wire for the coil diameter. The correction factor is applied to scale up the stress S to better predict the fatigue lifetime of the spring.)
The history of the garage door could date back to 450 BC when chariots were stored in gatehouses, but in the U.S. it arose around the start of the 20th century. As early as 1902, American manufacturers—including Cornell Iron Works—published catalogs featuring a "float over door." Evidence of an upward-lifting garage door can be found in a catalog in 1906.[4]

The technician that came out, Todd Noel, was very friendly and professional. He fixed my problem quickly and did not overcharge me for something that I did not need. He also made some great recommendations for future work. Because of his level of service and my customer experience, I highly recommend Precision and will use them again in the future.

Every thing the tech demostrated was helpful, he knew how to do his job even if his eyes were shut. Very knowledgeable, took time out to explain every detail about the install process. Very highly satisfied. A d would love to have him for future additional repairs. Would definitely recommend sears and would use you guys again thanks mr.technician for a job well done.
I make no recommendations of, and have no connection to, any of the following suppliers. These are just those whom I have learned about from my Web searches, from correspondence with those sending email about their experiences, or directly from the suppliers. I have removed several contacts that were generating complaints to me from dissatisfied customers. I have added this list to this page due to all the email queries I was receiving daily asking where to obtain parts. If you are a supplier and would like to be added to the list, see my email address at the end of this page.
Angle iron provides a stronger installation and reduces vibration, which helps extend the opener’s life span. In an unfinished garage, attach the angle iron directly to the face of a joist with 1-in. lag screws. For finished ceilings, attach angle iron along the bottom of a joist with 3-in. lag screws. Hang the opener using two more lengths of angle iron and nuts and bolts. Use lock washers or thread-locking adhesive to keep vibration from loosening the nuts.
When your garage door starts acting up, more often than not it is telling you it's time to do a bit of maintenance. So, before hitting the panic button, try these simple repairs. First, examine the rollers and tracks. If you can't remember the last time you cleaned them (and they look the part!), give them a good brushing and then add some lubricant. Next, perform these simple garage door maintenance tasks.
If your door feels heavy, it is likely that your springs have started to wear down and are no longer capable of bearing the weight that they once did. Now, don’t worry, just because a spring is starting to lose its strength doesn’t mean it will snap at any moment. However, simultaneously, a weak spring isn’t any safer to try and repair on your own.
I was having an issue with my garage door that turned out to simply be the remote lockout being accidentally engaged. I called Aaron’s Garage Door Service and rather than sending a tech out and charging me for such a simple problem, they explained the solution over the phone. I really appreciate businesses with a sense of integrity like that! If I ever have a real garage door problem, I will absolutely be calling these guys!
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.
Install the stiffening strut on top of the top section of steel doors with the section lying flat. Then install the opener bracket that replaces the center bracket between the top two sections. While you’re working on the sections, protect them from scratches by putting carpet scraps on top of your sawhorses. Now, slide the rollers into the roller brackets.
Wood doors range from midprice to very expensive, depending on whether they consist of a lightweight wooden frame filled with foam insulation and wrapped in a plywood or hardboard skin (the least expensive) or are true frame-and-panel doors made of durable mahogany, redwood, or cedar. Wood doors usually carry a short warranty, perhaps only one year.

Before setting the last panel in the tracks, set the power unit on the actual frame and slide it in the ends. Hardened screws are used to attach the center bracket (Image 1). They are a different type screw — they are tougher and will last a lot longer. Make sure the bracket is level (to the eye) when installed and leave the bracket a little loose so adjustments can be made. Fasten down all the hinges (Image 2).

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.

“This is not a simple thing to install,” cautioned one of our testers. “It's likely that you’ll make a few trips to the hardware store even if you’re very handy and have a relatively complete set of tools.” That said, our reviewers thought that this opener’s instructions themselves were very clear and that once setup was complete, the device “worked without lots of fiddling.” Another plus was its added security features, like keyless entry and smartphone app integration. Lastly, our testers did wish it had a built-in camera to allow surveillance in the garage at all times.
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.
Adding a new garage door provides a dramatic difference in your home’s appearance. When neighbors pass by, when guests pull up, or when you return from work, your house will have a distinct beauty that makes it a landmark of the neighborhood. The unique look you’ve always imagined — as well as the material, the finish, and the insulation can be found in our wide selection of garage doors.

The usually recommended rule for a door being properly balanced is that it should lift "easily" through all its travel. The door may also remain stationary if let go somewhere around the middle of the travel, but a smoothly rolling door many not show this behavior (while a sticky track will!), so easy travel is the only reliable test for proper balance. A difficult door may be due to stiff bearings or rollers in the mechanism, tracks out of alignment, etc., not necessarily the torsion spring adjustment.
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.
There are plenty of garage door accessories to make your garage safer. Sears carries replacement safety sensors that will detect anything in the way and keep it from shutting. If you have a small garage or it's full of gardening equipment, a laser parking assistant will help you find the perfect spot every time. You can set it so it hits the perfect spot on your dash as you pull in. You'll also be able to find new tracks to replace worn opener tracks.

Spring index lower limit: DASMA standard 102-2004 provides a lower limit of 6 for the spring index, which is symbol C in our formulas above (section 9.3). Other interesting items in this standard include an upper limit for how much the door sags when raised (no more than 1/120 of its width, section 9.2.1), that each of the two bottom brackets should sustain twice the door assembly's weight (section 9.2.2) for a total safety factor of about 4, and that the lift cables should provide a safety factor of 5.
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.
If your garage door is opening slowly or making a lot of noise, the problem may not be your opener. So before you buy a new one, check for broken or wobbly rollers and brackets. But don’t replace the bottom roller bracket yourself—the cable attached to it is under extreme tension. You’ll need to call a pro. If you’re replacing the rollers, get nylon rollers. They operate quieter than steel rollers and cost only a few bucks more. Next, check the torsion spring (mounted on the header above the door opening) to see if it’s broken. When one breaks, you’ll see a gap in the coils. You’ll need a pro to replace a broken spring.
Door repair business advice (warning to consumers, you are not allowed to know this): Thinner wire is excellent for shortening spring lifetimes, lightening your inventory on a service truck, and getting paid for frequent service calls. This is why your industry chooses to set "standard" springs to have thin wire and despicably short lifetimes. If you want to maximize profits and fleece your customers, install springs that predictably break in about 7 years on a door that should last decades, even though it is just as easy for you to install slightly more expensive springs that should last the life of the door. Remember that the customer wanted the cheapest price, so you need not feel any guilt about this low-balling.
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.
The not-so-competitive advertising trick: How about this racket: We have all heard how you should get at least three bids for any home improvement jobs, right? In some areas the largest ads in the yellow pages are from a single business using various names and phone numbers, masquerading as independent competitors. When you call asking for prices, "they" all quote you very high numbers. You are tricked into thinking you have shopped around for the prevailing price. (The more modern version of this is multiple Web sites that all direct you to call the same person.) If you've ever had to call a plumber you may have unknowingly been a victim of a similar trick.
Sectional: Also known as a raised panel door, this door is the most common. It is made of several horizontal panels hinged together, fitted with wheels and mounted within a track. The biggest advantage of this door is it takes up relatively little space and easily controlled with a standard remote garage door opener for a nominal cost. Their moving parts are readily accessible which can keep repair costs low. The average cost for sectional door repairs is $128.
Tom was professional, knowledgeable, and very friendly. He arrived at my house within the time frame he said he would (nothing is worse than a late technician).

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.
Insulation, which increases energy efficiency and can help to lower utility bills, is crucial when a garage door is attached to the home. In this case, doors with high R-values are preferred. This means it has insulation that can keep the heat in. The higher the R-value, the better insulated your garage will be against outside noise and cold and hot air.
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.
Garage door manufacturers typically produce garage doors fitted with torsion springs that provide a minimum of 10,000 to 15,000 cycles and are guaranteed for three to seven years. One cycle is a single opening and closing sequence. Most manufacturers offer a 30,000 cycle spring. However, it is important to remember that if the weight of the garage door is increased by adding glass, additional insulation, or even several coats of paint, the life of the torsion spring may be greatly reduced. Additionally, springs at highly humid environments, such as coastal regions tend to have a significantly shorter cycle life, due to the corrosive cracking.
This work is risky, but the risk is comparable to doing your own car repairs, or climbing on the roof of your house to clean your gutters. These are dangerous things that many people can do safely, but that safety depends on intelligent understanding and application of proper techniques. Professional door repair technicians, who are fully knowledgable, skilled, and experienced, report that they nevertheless are injured from time to time, despite their best efforts. Coldly evaluate your abilities and motivations, to judge whether you can manage the risks of this work for the benefit of the money and time you might save.
Furthermore, newer doors come with more improved security features, helping to improve the way you protect your home and loved ones. While older doors are easy to break into, whether through breaking the lift mechanism or even using a universal garage door remote, new doors come with many redundant security features, which will go a long way in deterring even the most ingenious burglar.

Trading diameter for length: Observe that in the spring rate formula in the table above, factors D (diameter of coils) and N (number of coils) appear together in the denominator of the spring rate formula. Algebraically, given equal wire sizes, this means that the product of the coil diameter and overall length produces the spring torque, not the diameter or length alone. Physically, this means that you can trade off torsion spring coil diameter versus overall length in inverse proportions to maintain the same torque rate. Trade-off example: A spring with 2-inch diameter coils that is 36 inches long equals a 1.5-inch diameter spring that is 48 inches long, because the product in both cases is 72 (inches squared). This assumes that wire size is equal in the trade-off, and that you have not counted dead coils in the length. Service technicians use this principle to make quick substitutions for what's on their truck versus what you need. But if you understand this, you're ahead of many technicians who don't know this trick. Maybe now you can educate the next one you hire.

Tools in Action says the Ryobi Ultra Quiet has plenty of versatility, as you can plug devices into the opener hardware, like a Bluetooth speaker, a fan, or even an 18V Ryobi cordless tool battery. When the opener has power, it will charge the battery. But if your home ever loses power, the 18V battery works as a backup to the garage door opener, allowing it to operate normally.

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.
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]
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.
And for some extra features, you'll appreciate accessing the system through the MyQ smartphone app. You can set up this Chamberlain opener to automatically close the door after 1, 5, or 10 minutes, which is great for people who are a bit forgetful. We also really like the motion-detecting control panel, which turns on lights whenever it records nearby movement.
