Stress and lifetime: Calculating the maximal stress in the wire is useful for estimating the lifetime. Using the formula above, the bending stress S in the spring wire is 32*238/(π*0.2253^3) = 212 Kpsi. The spring index C is D/d = 2.23 / 0.225 = 9.88. The Wahl correction factor is Kw = (4C-1)/(4C-4) + 0.615/C = 1.15. The Wahl-corrected stress is Kw * S = 1.15 * 212 Kpsi = 244 Kpsi. This predicts about a 10,000-cycle lifetime, which is the standard "cheap spring" configuration originally installed. Note that while this stress is proportional to the torque being applied, it is also in proportion to the inverse third-power of the wire size. Thus slightly heavier wire sizes (and suitably adjusted D and/or L) radically improve the expected cycle lifetime of the spring.

We specialize in installation, repair and maintenance of residential and commercial garage doors. Our garage doors are reliable, affordable and most importantly safe.We know a great garage door installation is nothing unless you have a great garage door to install. That’s why we feature the best brands when it comes to garage doors and garage door openers. We feature doors by Clopay, as well as, door openers by Chamberlain and LiftMaster Professional.
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.
Though you can do some maintenance to your garage doors on your own, it may be a good idea to schedule routine inspections with a professional. A typical service call will include a manual inspection of the door and opener. Then adjustments can be made including spring tension, chain/belt tension, limits and force adjustments and door lubrication. Fees for this service vary from place to place, but garage door repairs typically cost between $147 and $340.

While there might not be a huge price range when it comes to garage door openers—they are all quite an investment—there a few less expensive options to consider. Here’s a great budget option from Chamberlain. It has a motor that’s equivalent to ½ horsepower and chain drive system that is quick and easy to install. You can also connect it to the MQ technology (gateway sold separately) to use with your smartphone. The product comes with two three-button visor remote controls, a multi-function wall control, as well as a wireless keyless entry system. It comes with a 10-year motor, two-year parts, and one-year accessories warranty.
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.
Most situations allow you to replace spring(s) without removing the assembly from the wall, if there is enough clearance in the surrounding garage structure at the ends of shafts. By unbolting the end bearing plates and removing the drums, you can run the springs down to the ends of the shaft to remove and replace the springs. This avoids the balancing act of holding a long, wobbly, heavy shaft while climbing up and down a ladder. This is how the professionals get the job done in a few minutes.
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.
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.
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.
Two of the spring references specifically for the garage-door industry are the APCO Spring Manual by Bill Eichenberger, and the Torsion Spring Rate Book by Clarence Veigel; these give tables of spring sizes and torque constants. Spring engineering principles in general are described in the Handbook of Spring Design published by the Spring Manufacturer's Institute; the formulas allow you to calculate torque constants knowing only the geometry and the Young's modulus of the material. You can also find some brief spring information in standard references like Machinery's Handbook and Marks' Standard Handbook for Mechanical Engineers.
Safe automatic door openers. All automatic openers must now have an auto-reversing mechanism and photoelectric eyes located near the floor on both sides of the door (see photo). If the door is closing and the beam between the eyes is interrupted, the door will automatically reverse. If the eyes aren’t connected, the door won’t operate. For instructions on how to install a new garage door opener, see How to Install a Garage Door Opener.

Garage door repair is a specialized job, which is typically handled by a garage door repair service. Professional garage door repair technicians can test or repair a garage door system and fix cosmetic blemishes on doors. Common requests include help with jammed or inoperable doors, slow or erratic doors, unusual sounds, dents or scrapes on the door, and general system testing. Garage door repair professionals can work on single-car, double-car and RV-size garage doors.
“Especially on houses where the garage is front and center, the garage door absolutely has to look good,” says Casey McGrath, a real estate practitioner in Kitsap County, Wash. And it has to operate smoothly: Americans use the garage more than any other entry to the house, including the front door, according to a survey commissioned by window and door manufacturer JELD-WEN.
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.
Winding "up" starts out easy. It finishes at the proper number of turns, by which time you are pushing against the maximum torque. Count the turns of spring winding from when the springs are slack. To be sure you're winding the right direction, all you have to remember is that proper winding makes the spring smaller in diameter and longer in length as it twists "in". On the standard door (most common), this means you push the winding bars up to wind up the spring, which is an easily remembered rule. This is very apparent and should be verified during the first few easy turns. You can also think about the correct winding direction in mechanical terms, namely which way the reaction of the spring will torque the shaft and drums, which in turn will lift the cable. This should all make perfect sense before you attempt the manipulations.
Electric Garage Door Openers – Service and repair of the electric garage door opener itself, including the lift mechanism that pulls the door up and guides it down. This is typically not part of the garage door itself and is serviced and repaired on its own interval. Typical service includes inspection, repair, adjustment, and lubrication if needed. Also, we typically inspect the mounting of the unit as well as its attachment to the door itself.

One of these "sproing" events at our house finally motivated me to research how these repairs are done. This happened in 2002, when my wife parked the chariot and shut the door. After the door closed, there was a horrific noise that she could only astutely describe as, "a big spring snapping and vibrating". Although I have hired professionals several times in the past to install or repair garage doors, the difference this time was the innovation of Google and newsgroups like alt.home.repair. I was determined to learn the process and to search for online parts vendors.
For garage doors with windows, try to match the glass style of your house windows to provide a more consistent look. It’s also recommended that you install insulated windows if your garage is heated or air conditioned. If you opt for an uninsulated garage door, make sure it’s made of thick steel – specifically 24-gauge. Thicker steel will help prevent dents.
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.

Screw-drive garage door openers are another type of direct-drive garage door opener. The screw-drive's relatively simple mechanism, which moves up and down a threaded steel rod, makes for a powerful, low-maintenance garage door opener. They are quieter than chain-drive openers, and are fast workers, but, like direct-drive openers, they tend to be pricey.
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.
Technician Mark called 1/2 hr before coming. Very knowledgeable and friendly technician. Originally scheduled as a tune-up but after pointing out several potential problems I decided on the complete overhaul package. All parts were on the truck. Technician completed job in a little over an hour. Very satisfied. Definitely would recommend.Bob PNorth Myrtle Beachread more
We specialize in all varieties of garage door repair work. We have the tools and knowledge to get the job done safely. It can be somewhat dangerous to take on a garage door repair on your own, and most garage door companies will advise against attempting a DIY fix. There are some hazards to watch out for when working around these heavy and high tension doors. We recommend you give the experts at Girard's a call to address the issue in a safe and timely manner.
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.
I was having an issue with my garage door that turned out to simply be the remote lockout being accidentally engaged.
