How To Fix Garage Door Cable

Fixing a garage door cable is a task that, while seemingly daunting, is manageable with the right instructions and safety precautions. Before embarking on this repair, ensure you have the necessary tools, including locking pliers, a ladder, wrenches, and replacement cables. It is also essential to understand the risks involved; garage doors are heavy, and the springs can be dangerous if handled improperly.

Tools and Materials Needed

  • Locking pliers
  • Adjustable wrench
  • Sturdy ladder
  • Replacement garage door cables
  • Gloves
  • Safety glasses

Step-by-Step Guide to Fixing Garage Door Cables

Step 1: Secure the Door in Place

Before you start, make sure the garage door is closed. Secure it by clamping locking pliers onto the track on both sides of the door.

Step 2: Loosen the Cable Drum

Climb the ladder and locate the cable drum at the top of the door. Use the adjustable wrench to loosen the set screws on the drum.

Step 3: Replace the Cable

Remove the old cable from the drum. Thread the new cable onto the drum, following the same path as the old one, and tighten the set screws.

Step 4: Attach Cable to the Bottom Bracket

Move to the bottom of the door and attach the other end of the cable to the bottom bracket. Make sure the cable is taut.

Step 5: Test the Door

Carefully remove the locking pliers and manually lift the door halfway. If it stays in place, the cables are properly balanced. If not, adjust the tension.

Step 6: Fine-Tune and Secure

Once the door is balanced, double-check all set screws and ensure everything is tight and secure.
