Contrary to popular belief the lifting mechanism of your door has little to do with the garage door opener. It’s actually the garage door springs that Broomfield homeowners can thank for the smooth, effortless way the door is lifted up and tucked away into the ceiling of the garage. But the springs themselves are not connected directly to the door. Instead, they’re connected to pulleys or drums over which run cables which transfer the energy of the springs to the task of lifting the door. Typically there is one “lifting” cable on each side of the door. If either of these cables break the door will raise and lower unevenly and will eventually fail altogether.
