2.1 Two important assumptions will help you execute this replacement safely. First, assume that the springs are going to break as you unwind or wind them. To avoid injury, clutch the bars firmly on the ends furthest away from the cones and stand securely on a sturdy ladder, not on chairs or cans turned upside down. Keep clothes and body parts away from the springs. Wear safety glasses.
If you pull the red emergency release rope on your automatic opener and you still can’t lift the garage door, you probably have a broken spring. The counterbalance spring is what lifts the garage door, not the garage door opener. If the spring is broken, the door is dead weight. A garage door can be lifted, but it is going to require some muscle to get it up. It is also important to lift the door evenly so it does not jam in the tracks.

• Extension springs: Garage door extension springs stretch to provide lifting power for the door. These springs are typically made of steel and mounted above the horizontal track of the garage door. A safety cable should run through your extension springs to prevent possible injuries or property damage. Extension springs are the most common type of garage door spring for residential use and can break after excessive usage.
