Drive type Garage door openers work in a variety of ways. A chain-drive model raises and lowers doors with a metal chain — these tend to be inexpensive and able to handle heavier doors, but they’re loud. A belt-drive opener uses a belt and operates more smoothly and quietly. Screw-drive openers, which lift doors with a threaded steel rod, are also quiet and don’t require much maintenance. Finally, a direct-drive opener operates as a single unit — the whole contraption moves to lift the door. These tend to be the quietest, smoothest mechanisms available.
Note that I am measuring a spring that is fully relaxed because it is broken!. The length of the relaxed, unbroken spring is the specification of interest. It is harder to measure unbroken springs on an intact door because the springs should not fully unwind, even at the top-of-travel. If you can't be certain of the spring diameter from indications on the cones, then you have to go through an unwinding procedure to relax them fully for measurement, or perhaps reckon the size from measuring the somewhat smaller diameter at the nearly unwound condition when the door is at its top-of-travel (although one should not attempt to raise a door with a broken spring).
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.
Garage doors provide one of the major entryways into your home. Therefore, it is essential to ensure that they are secure and in good working order. If you are having problems with your current door, then you need to have a professional determine if it can be repaired or if it will need to be replaced. Here are some of the most common factors that will affect the cost of a garage door repair.
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.
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.

The Certified Technician, Rey Lopez, was competent, professional, polite, and willing to work. He quickly removed the old door and installed the new one. He then explained the vast differences between what we originally had and what we'd just purchased (stronger spring/tension rates; increased viability of door opening/closing life; beefier hardware; plastic vs. nylon rollers; stronger door reinforcement). Ray performed with alacrity his tasks and then demonstrated the quiet, solid way the door retracted--no banging after the initial rise from the ground. Finally, his attention to detail was so precise that he enabled another remote controlling all three doors, plus he capped some frayed wires, thus solving the problem of why the door opened intermittently. I would rate him a "6" on a scale of "1-5", meaning he went above and beyond our expectations. His "can do" attitude, coupled with the deference he showed, will take him a long, long way. May HaShem richly bless him in his endeavors!read more
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.

If the spring is broken near a winding cone, you might think you can remove and discard the short broken piece of spring from the cone, clean up the end of the long remaining spring, and insert that end into the cone. This is another extrememly risky improvisation. The shortened spring is not going to have the correct weight-bearing characteristics for the door, so you will not be able to balance the door properly. The shortened spring will be proportionately overwound, resulting in extra stress that will increase the expectation of another fracture. And the aging and history of the original spring being broken greatly increases the likelihood of another fracture at other locations.
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.
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.
“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.
Note the left winding cone with red spray paint. This shpritz of paint is applied to create fear and doubt in the mind of the do-it-yourselfer. Sometimes it is a color code for the wire size (using a DASMA standard, red indicating 0.2253 inch diameter wire). Sometimes it indicates the winding direction: red may indicate right-hand winding, but don't rely on that; do you own independent analysis. Sometimes it is a manufacturer's private code for another dimension than wire size. This color code is for the installer's information when the spring is new; I would not depend on interpreting the color code properly on an old spring, since one can't be certain of a correct interpretation without documentation from the original supplier.
Step 2: Check the tracks with a level to make sure they're properly aligned. Horizontal tracks should slant slightly down toward the back of the garage; with roll-up doors, the vertical sections of track should be exactly plumb. Both tracks must be at the same height on the garage walls. If the tracks are not properly aligned, loosen but do not remove the screws or bolts that hold the mounting brackets, and tap the tracks carefully into position. Recheck the tracks with the level to make sure they're in the right position; then tighten the screws or bolts at the mounting brackets.
