How to Fix a Garage Door Cable and Tips for Replacing It

When Do You Need a Garage Door Cable Repair?

Before you learn how to replace the cable on a garage door, it would help to get a general understanding of the function of cables. Cables are an essential component of garage doors. Modern doors have two cables on either side of the garage door. They work with the sirens to make sure that equal energy is distributed as the heavy garage door is lifted. Most doors have lifting and safety cables.

Lifting Cables

Lifting cables work with the springs so that energy is equally distributed when the door opens and closes. This ensures that the door moves smoothly whenever you want to open it. While springs are essential for this, this movement cannot be done without cables. Springs rely on the cables to redistribute the garage door weight. Each door has two cables on both sides.

Safety Cables

These are placed to prevent serious injuries should the extension springs snap. Safety cables run from one end of the garage door frame to the other. They pass right through the extension springs. If the extension springs break, the safety cables will prevent the springs from hanging down and hurting people.

So if the cables break, should you repair them by yourself? Sometimes, it may be safe to try to repair or replace cables by yourself. But the fact that you have to deal with lifting the heavy garage door, the probability of the cables snapping when you are trying to fix the door may put you at risk of causing injuries to yourself. So if you are not sure or have no experience on how to repair a broken cable on a garage door opener, it is safer to leave this task to the professionals.
