With over 300 independently moving parts, your garage door is a deceptively complex piece of equipment. To help prevent malfunctions and break-downs, it is a good idea to occasionally perform a garage door tune-up to keep all of these parts in good working order. A regular tune-up service by a Sears professional can prevent unexpected door problems and prolong the life of your existing equipment.
I've provided this information for free, in hopes it will help you either fix your door yourself, or find a competent professional service to do it for you at a reasonable price. If you've been helped by this Web page, as many have, all I would ask is that you create a link to this page (http://www.truetex.com/garage.htm) from any pages you maintain.

Containment cables. When old extension springs break, the springs and cables become heavy whips that damage cars and even injure people. To solve the whipping problem, manufacturers now offer containment cables that run through the center of side-mounted extension springs. If you have extension springs and don’t plan to replace your door, make sure the springs have these containment cables, or have a professional install them.
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 wire size and winding direction are easily discovered and proved, as I will explain below. You absolutely must know and understand the critical measurements of your old springs to order replacements. This assumes that the old springs were the correct to begin with; it is not uncommon to have incorrectly sized springs on a door due to a previous sloppy installation, or a significant change in weight of the door.
Additionally, the B970 includes encryption features that prevent others from hacking the system to gain entry to your garage. Expert reviewers like this garage door opener a lot. The Tool Spy says the Chamberlain B970 justifies its higher price point by delivering excellent build quality and anti-vibration features. Consumer Search and Garage How To also approve of this unit.
The winding technique is simply to (un)wind as far as one rod will go, where it is pressed against the top of the door, or nearly so, by the unwinding torsion. You insert the other rod in the next socket, remove the first rod, and continue. At any point you can stop and rest by leaving the active rod pressed against the door, where it will be held by the unwinding force. I would make a quarter-turn increment that way, and let go for a moment to collect my attention for the next increment, almost in a quiet, meditative alertness. While you can go from one quarter-turn and rod-swap to the next continually without letting go, working fast against the steady tension seemed to invite a kind of shakiness in my arms that was a bit unsettling. It isn't that there is much physical exertion, it is more that the tension is unrelenting, like peering over a precipice.

The lucky-for-you-I-found-another-problem trick: Another trick is to suggest your automatic opener was damaged (or "compromised") by the additional load or shock presented by the failure of the spring(s). The plastic worm gear used in the most common openers (see above) wears normally over the years and tends to leave a lot of debris inside the opener housing. Removing the opener cover reveals a lot of plastic shavings that may be cited as "evidence" you need a new opener, when the gears are actually still serviceable. Nevertheless, you may have indeed worn out the gear if you repeatedly cycled the door with the opener despite having broken springs, which is possible if you have a very lightweight door.
Called for an appointment and was surprised that I could have a tech come the same day. Matt arrived ahead of schedule, inspected the garage door and gave me a tune up to get things working properly again. He explained what would need to be done in the future, and the cost. I will certainly call them when the time comes to get that work done.read more
You might genuinely need some extra parts when you thought you simply needed a broken spring replaced, and a good serviceman will perform a simple inspection to identify such parts. Nor is it unreasonable for a business to charge separately for a service call versus repair work actually performed. But the best protection for you as a buyer, being somewhat at the mercy of whomever you decide to bring on site, is to understand what is being done, and ask intelligently for a clear explanation or demonstration of why extra parts are required.
