DIY Guide: How to Repair Garage Door Cable

3 min read

Garage doors are essential components of any home, providing security and convenience. However, like any mechanical system, they are prone to wear and tear over time. One common issue that homeowners may encounter is a broken or damaged garage door cable. But fear not, with some basic tools and a little know-how, you can easily tackle this repair yourself. In this guide, we’ll walk you through the steps to fix a broken garage door cable.

Understanding the Problem

Before you begin the repair process, it’s essential to understand what you’re dealing with. Garage door cables are responsible for supporting the weight of the door as it opens and closes. Over time, these cables can become worn, frayed, or even snap, causing the door to malfunction. If you notice any signs of damage such as sagging or uneven movement, it’s likely that your garage door cable needs to be replaced.

Gather Your Tools

To tackle this DIY project, you’ll need a few basic tools:

1. Safety Glasses and Gloves: Protect yourself from any potential hazards.

2. Adjustable Wrench or Socket Set: To loosen and tighten bolts.

3. Vise Grips: For securing the cable during the repair.

4. New Garage Door Cable: Make sure to purchase the correct size and type for your door.

5. Ladder: To access the garage door mechanism safely.

Steps to Repair Garage Door Cable

1. Safety First: Before starting any work, disconnect the power to your garage door opener to prevent accidental activation. Also, ensure the door is fully closed to avoid any accidents.

2. Release Tension: Use a pair of vise grips to secure the garage door cable below the bottom roller. This will prevent the door from moving while you work.

3. Remove Old Cable: Using an adjustable wrench or socket set, loosen the bolts holding the cable in place at both ends. Carefully remove the damaged cable from the pulley and drum.

4. Install New Cable: Thread the new garage door cable through the pulley and drum, ensuring it follows the same path as the old cable. Tighten the bolts securely to hold the cable in place.

5. Reattach Bottom Bracket: Once the cable is installed, reattach the bottom bracket to the door using the provided bolts. Make sure it is securely fastened to prevent any issues with the door’s operation.

6. Test the Door: With the repair complete, carefully remove the vise grips and restore power to the garage door opener. Test the door to ensure it opens and closes smoothly without any issues.


With these simple steps, you can successfully repair a broken garage door cable on your own. However, if you’re unsure about tackling this task yourself, or if the damage is extensive, it’s always best to seek professional help.
