• Pliers
• Locking pliers or C-clamps

1. Release the Tension on the Garage Door Springs

   • Torsion Springs: If your garage door uses torsion springs, use winding bars to safely unwind the springs. Insert the winding bar into one of the holes on the winding cone of the spring. Hold it securely while you loosen the set screws on the winding cone with a wrench. Carefully let the tension off the spring by moving the winding bars.
   • Extension Springs: For extension springs, open the garage door fully to release the tension. Secure the door in place with locking pliers or C-clamps on the tracks.

2. Remove the Old Cable

   • Once the tension is released, detach the cable from the bottom bracket on the garage door. Use pliers to remove any clips or fasteners holding the cable in place.
   • Follow the cable up to the cable drum near the top of the garage door. Detach the cable from the drum, noting how it is routed for easy reinstallation of the new cable.

3. Install the New Cable

   • Attach one end of the new cable to the bottom bracket of the garage door. Ensure it is securely fastened.
   • Route the cable up to the cable drum. Loop the cable around the drum, following the same path as the old cable. Make sure the cable is seated correctly in the grooves of the drum.

4. Tighten the Springs

   • Torsion Springs: If you have torsion springs, use the winding bars to carefully wind the springs back up. Insert the bar into one of the holes on the winding cone and turn it in the correct direction to add tension. Tighten the set screws on the winding cone to secure the spring.
   • Extension Springs: For extension springs, remove the locking pliers or C-clamps from the tracks and lower the garage door slowly.

5. Check the Alignment and Tension

   • Ensure the cable is properly seated on the cable drum and the tension is even on both sides of the garage door. Adjust if necessary.
   • Reconnect the garage door opener and test the door to ensure it opens and closes smoothly without any hitches.

6. Final Safety Check

   • Inspect the entire installation to ensure all components are secure and properly aligned.
   • Test the door several times to confirm that the cable is functioning correctly and there are no unusual noises or movements.

Replacing a broken garage door cable can seem daunting, but by following these steps and prioritizing safety, you can successfully complete the task.
