Garage door cables are an essential component of a properly functioning garage door system. They work in tandem with springs to lift and lower the door safely and smoothly. Over time, these cables can fray, wear out, or snap due to regular use or lack of maintenance. If you’re dealing with a broken garage door cable, it’s crucial to address the issue promptly to avoid further damage or safety hazards.
This blog will guide you through the process of replacing a broken garage door cable. However, garage door repairs can be dangerous, so if you’re unsure or lack experience, it’s best to contact a professional.
Step 1: Gather Tools and Safety Equipment
Before starting, ensure you have the necessary tools and safety gear, including:
- Replacement garage door cables
- Wrenches
- Screwdrivers
- Locking pliers or C-clamps
- Ladder
- Gloves and safety glasses
Step 2: Disconnect the Garage Door Opener
To prevent accidental activation, unplug the garage door opener or disconnect it from the power source. Ensure the door is fully closed before proceeding.
Step 3: Secure the Garage Door
Use C-clamps or locking pliers to secure the garage door in place. This step prevents the door from moving while you’re working, reducing the risk of injury.
Step 4: Remove the Broken Cable
- Locate the broken cable attached to the bottom bracket of the door and the cable drum on the shaft.
- Loosen the tension on the torsion spring by using a winding bar to rotate the spring, carefully relieving pressure.
- Detach the broken cable from the drum and bottom bracket.
Step 5: Install the New Cable
- Attach one end of the new cable to the bottom bracket.
- Guide the cable up to the drum and wrap it around the grooves of the drum.
- Secure the cable to the drum, ensuring it is tightly wound and properly aligned.
Step 6: Adjust the Tension
Using a winding bar, carefully adjust the torsion spring’s tension to ensure smooth operation of the door. This step is critical; improper tension can lead to safety hazards or functional issues.
Step 7: Test the Door
Remove the C-clamps or locking pliers and manually lift the garage door to test its movement. Ensure the door opens and closes smoothly without jerking or misalignment. Reconnect the garage door opener and test it again using the automatic mechanism.
