The technician, Robert Helton, was very pleasant, helpful, and professional. He repaired the garage door opener expeditiously and explained why it hadn't worked properly. He also checked the chain mechanism and the door itself and showed me how to manually work the door should I need to do that in the future. I was very pleased with this repair work.
Most home centers don't carry all the replacement parts you'll need for garage door spring replacement, and most garage door service companies won't sell you springs. So you may have to order the parts online and wait for the shipment to arrive. Garagedoorpartsusa.com and stardoorparts.com are two online sources . First, inspect the condition of your cables and brackets. If you see any frayed strands on the cables or rust on the bottom brackets, replace them now before they fail. Bottom brackets cost about $15 per set. Premium-quality cables (listed as “7x19”) last much longer than economy cables and cost only about $4 more. So it's smart to buy the better cables for about $12 per set.
Gather the supplies and tools needed for changing the springs safely. In addition to the torsion springs you'll need a minimum of one or two 10" vise grips, an adjustable wrench, and two 1/2" X 18" winding bars. Most hardware stores sell 1/2" X 36" steel rods that can be cut in half. You'll also need a firm ladder and a rag for cleaning your hands. A ruler and a file may also be necessary; a socket wrench and sockets would shorten the time required. Finally, make sure your garage is lighted well.
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.
Unfortunately, if the metal contraction happens quickly — for example, after a rapid freeze — the contraction may actually cause your door track to bend. This is a much more serious problem, and may require repairs further down the road. However, if the bending in your track is minor, your door will still function properly, even if it does make a little more noise.
Thank you, thank you, thank you for sharing your knowledge. I just replaced our shower cartridge and our leak is FIXED!!!!!!! Your instructional was clear and concise. I did purchase 2 cartridges first, because I did not know the type it was and could not pull it out without the plastic cover it comes with. Fortunately, it was one of the two. By the way I'm a 63 year old woman. If I can do it, anyone with internet and a little patience and an hour can do it.....
Test the door balance. A garage door should require only a few pounds of pressure to move it up and down. If springs wear out and lose their resiliency, a power garage door opener may need to work extra hard to lift the door. This can quickly wear out the motor on the opener. Replacing worn-out springs is usually a job for a professional technician.

Grab a tape measure and press the hook between two spring coils and note the length of 20 coils. Then measure 40 coils. Convert the measurements to a decimal (4-1/2 in. to 4.5 in., or 4-1/8 to 4.125, for example). Divide the two measurements by 20 and 40 to obtain the spring's wire diameter. Here's an example: 4.50 divided by 20 = .225-in. wire diameter; 9.0 divided by 40 = .225-in. wire diameter. If the two results match, you've measured correctly.
9.9 Go to the other side of the garage door and insert the end of the cable into the drum. Rotate the drum until the cable is tight. Slide the drum against the bearing and push the shaft to the right. The marks should line up. If they don't, figure out why and correct the problem. It could be a stuck cable, the garage floor may have shifted, or the vertical angle that helps support the bearing plate may have loosened and shifted. Many garage doors have been installed with a gap between a drum and a bearing plate. The cable drums should always be flush against the race of the bearings.
