A torsion spring counterbalance system consists of one or two tightly wound up springs on a steel shaft with cable drums at both ends. The entire apparatus mounts on the header wall above the garage door and has three supports: a center bearing plate with a steel or nylon bearing and two end bearing plates at both ends. The springs themselves consist of the steel wire with a stationary cone at one end and a winding cone at the other end. The stationary cone is attached to the center bearing plate. The winding cone consists of holes every 90 degrees for winding the springs and two set screws to secure the springs to the shaft. Steel counterbalance cables run from the roller brackets at the bottom corners of the door to a notch in the cable drums. When the door is raised, the springs unwind and the stored tension lifts the door by turning the shaft, thus turning the cable drums, wrapping the cables around the grooves on the cable drums. When the door is lowered, the cables unwrap from the drums and the springs are rewound to full tension.[7]
If the sensors are misaligned, or if there’s an obstruction blocking the beam from reaching the other side, the door won’t close without you forcing it. If you’re unable to realign the sensors on your own, or think it’s something else causing the problem, call a garage door repair technician. If he or she is able to realign the sensors and fix the problem, it shouldn’t cost you much more than a service call fee, which averages $50 to $75.

“Every spring on every garage door will break,” says Jim Rice, owner of Broad Ripple Overhead Doors & Openers in Indianapolis. “After so many thousand times up and down, it gets metal fatigue and snaps. At least once a year, you should disconnect the garage door springs and lift the door up manually to see how well it’s balanced. Unless you hear metal screeching or something breaks, you don’t need us.”
Adding a new garage door provides a dramatic difference in your home’s appearance. When neighbors pass by, when guests pull up, or when you return from work, your house will have a distinct beauty that makes it a landmark of the neighborhood. The unique look you’ve always imagined — as well as the material, the finish, and the insulation can be found in our wide selection of garage doors.
An extension spring counterbalance system consists of a pair of stretched springs running parallel to the horizontal tracks. The springs lift the door through a system of pulleys and counterbalance cables running from the bottom corner brackets through the pulleys. When the door is raised, the springs contract, thus lifting the door as the tension is released. Typically these springs are made of 11 gauge galvanized steel, and the lengths of these springs are based on the height of the garage door in question. Their lifting weight capacity can best be identified by the color that is painted on the ends of the springs.
In many homes, the original garage door was installed during construction of the garage and the builder may have chosen the least expensive model. Decades later, the homeowner may decide to upgrade to a higher quality door. While appearance and cost will likely be the biggest considerations for most homeowners, other factors such as insulation value, ease of operation and safety features should also be considered. A highly rated garage door installation professional can offer more detailed advice.
