The nucleus of any garage door system is its opener. Easily overlooked, garage door openers are highly complex pieces of equipment, often containing dozens of intricate parts that work simultaneously with one another to consistently raise and lower your door. You'll know that you're getting the best from Sears as it's the home to America's #1 Garage Door Opener Brand, Craftsman*.
Door styles - in addition to the styles just mentioned, it is important to also consider additional features such as windows across the top of the door to provide light inside of the garage, the use of steel or wood frames to give decorative doors added security and stability, and insulation which can reduce energy costs in the attached garage by an impressive 15 to 20%; and
Once the chain is secure, separate it from both sides of the trolley. Disconnect the rail from the header bracket and move the rail off to one side. Slide off the old trolley, and slide on the new one. Reattach the chain and adjust the chain tension. Replacing the trolley on a belt drive and replacing it on a screw drive are similar procedures. A new trolley will cost $25 to $40 depending on your model.
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.
John, the service tech, was able to show up 2 hours ahead of schedule which worked out great. He knew the problem and readily offered a fix to repair the contractor grade spring and roll bar to a heavier duty version. Repair was done in a short period time and I could not be happier with the end result. He was friendly and knowledgeable and cared about getting it done right. Very pleased with the work and warranty.
Center and level the first section after you install the brackets. The door must be level even if the floor isn’t, so use shims under the section to level it. The rubber gasket on the bottom section will fill the gaps created by an unlevel floor. To hold the level in place, tape it to the section. To hold the section in place, lightly toenail a 16d nail into the frame and bend it over the section. Add brackets and rollers before setting them in place and stack one section on top of another, toenailing as you go up.
Wheel Track Obstruction – Try closing the garage door manually to see if there are obstructions on the wheel tracks. If that is not the case, examine your tracks for potential damage like dents and bends. Look at your door to see if it is hanging unevenly. If the track is damaged or the door is hanging unevenly, it is time to call a professional for repairs. Track repairs can typically cost $133 to $154. Cost for correcting the uneven hanging of doors themselves can vary greatly, but typically cost about $125.

Vincent was professional, informative, personable, efficient, and cleaned up his work area as he worked. I told him and now I am telling you... He my "Jordan" of garages. Give him a raise or at least a bonus. Thank you for sending him for my install. I am extremely pleased with my garage opener & with his install and information I am confident in its operation. Thank you.
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.

Technician gave me a window of 1-4pm, I called at 330 to see if he was on his way. He told me he would be there at 4pm, reason being was because of the amount of work orders he had that day. He was also by himself, had no helper. I was very satisfied that he was able to repair my garage door. He was very professional considering he showed up on a Friday afternoon on a 100 degree day. Thanks again
