Using your drill, add tension to the torsion spring. This system uses a single spring for a double door, but many manufacturers use two springs for a double door. The painted line on the spring acts as a gauge for the number of turns you put on the spring. To keep the bar from turning while you’re adding tension, attach a locking pliers to the bar on both ends of the spring. Apply lubricant for garage doors to the spring.

If you're clever and equipped with a welder, you might think you could get away by welding a broken spring back together. At least two factors make this extremely risky. First, the weld itself may fail, either due to insufficient basic strength, or weakening of the nearby parts of the spring. Second, the fact that the spring was old and fatigued enough to break once, means that it is likely to break again soon at other location(s).
Once the springs are relaxed and loose on the torsion shaft, the lift drums lose their tension on the lift cable, and the cable comes loose. The end of the cable is terminated by a press sleeve, which locks into a ramp on the drum. Different drum styles have a bolt or other method to fix the cable end to the drum. These steel cables are springy and won't stay in place without tension. If my pre-inspection had showed that these cables were worn or frayed, then I would have ordered proper replacements ahead of time from the spring distributor, since this is the opportunity to replace them. Standard hardware-store cable and fittings are not appropriate.

What is a battery backup? During a power outage, a battery backup allows your garage door opener to keep working. This is especially important when a wildfire is blazing. During the infamous California wildfires, many people were getting trapped in their garages. Several even died. California state Senator Bill Dodd was among those unable to get out, since he could not manually open his heavy wooden garage door. Drawing on his personal experience, Senator Dodd introduced a bill to make battery backups mandatory in the state of California. On August 16, 2018 the Garage Door Safety Bill passed with wide bipartisan support. As Cheryl Diehm, a Santa Rosa resident who testified before lawmakers, put it, "Make no mistake -- this legislation will help save lives."
Screw - Screw-driven lift systems attach a long screw to the motor to move the garage door.

I repeat my caution about the uncertainty of interpreting color codes. A professional installer reading this page emailed me to say that the red color indicates the springs are right-hand windings, not the DASMA color code for the wire size. But this photo shows both a right- and a left-hand spring, and both have the red paint on the cones and set-screws. I conclude it is prudent to make your own measurements and analysis. Do not rely on the colors on old installations. The only time I would respect them would be on new parts that carried documentation giving the code.

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.

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.
Roller doors ("Sheet Doors"-USA) are usually constructed of corrugated steel. They evolved from cover window and door coverings.[4] Other materials can be used (e.g.; transparent corrugated fibreglass) where strong impact resistance is not required. Corrugations give the door strength against impacts. A typical single car garage roller door has a preloaded spring inside the rolling mechanism. The spring reduces the effort required to open the door. Larger roller doors in commercial premises are not sprung (except USA) and use a manual pulley and chain system or a geared motor to raise and lower (roll up and roll down) the door. Roller doors cannot be effectively insulated.
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.

Looking for another budget option? This one, also from Chamberlain, is a good choice. With a powerful ½ horsepower motor, it’s reliable and rugged, especially paired with its industrial strength chain drive. The 100-watt bulb gives you some overhead light that guides you into your home from your car safely. It also comes with a pre-programmed, one-button remote that can be used over a long range. Plus, there are safety sensors that project an invisible beam helping to prevent the door closing on people or objects. And when the door is closed, you can rest assured it’ll stay closed and locked thanks to its Patented Security + 2.0 rolling code technology and PosiLock anti-theft protection.
The two set-screws in the winding cones have a 3/8-inch square head, which fits a 3/8-inch open-end wrench or 8-point socket, or a 7/16-inch 12-point socket or 12-point closed-end wrench. I carried an extra wrench in my pocket while winding, since I didn't want to be holding a wound spring that I couldn't set because I had dropped the wrench (although one could rest the winding rod against the door in this case while picking up a dropped tool).

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.
Our team of 100-plus technicians and service representatives takes care of you every step along the way. Our technicians are the best in the area. They’ll provide expert guidance as you consider your options, and then top-notch service to complete the repairs. When you want Cincinnati or Northern Kentucky garage door repair you can trust, choose AE Door & Window.

We love the fact that you can connect the Chamberlain Whisper Drive with a phone app for long-distance control, as well as the fact that the door will secure itself if you forget to do so. As with any technology, there is a learning curve in which the kinks will need to be worked out. But overall, very few owners have anything bad to say about the Whisper Drive. One smartphone user expressed his satisfaction with the product by saying, “I can check if I've left the garage door open and close it from my office!”

Chris was very professional & thorough. He arrived on time & was able to answer all questions that I had. I was extremely satisfied with the quality of the work he performed. I spoke several times on the phone with Mrs. Carol who keep me informed prior to, during, and after the installation of my garage door. She was very professional, easy to talk with and resolved any misunderstanding that I had.

Since their invention in the 1920s, electric garage door openers have come a long way. Garage door openers work by using a trolley connected to an arm that attaches to the top of the garage door and slides back and forth on a track, which opens and closes the garage door. When operating the motor, a chain or belt turns and pulls the trolley along the track. A good garage door opener will have a horsepower of 1/2 HP, 3/4 HP, or 1-1/4 HP. Garage door openers have the ability to open and close a limited number of times in power outage emergencies. Security is something else to consider when purchasing an opener. It's helpful to have sensors that will stop the operation of the garage door when a person, vehicle, or other obstacle is in the way.
