How To Replace Garage Door Cables

Garage door cables are an essential part of the door's operation. They help to lift and lower the door smoothly, and they also keep the door from coming off the tracks. If your garage door cables break, it's important to replace them as soon as possible to avoid further damage to the door or your vehicle.

Replacing garage door cables is a relatively simple task that can be completed in a few hours. However, it's important to follow the instructions carefully to avoid injury or damage to your garage door.

Step-by-Step Instructions

Safety first! Before you begin, put on safety glasses to protect your eyes from flying debris.
Unplug the garage door opener. This will prevent the door from opening or closing while you're working on it.
Disconnect the cables from the door. There will be two cables attached to each side of the door. Use a wrench to loosen the nuts that hold the cables in place, then disconnect the cables.
Remove the old cables. Once the cables are disconnected from the door, you can remove them by pulling them out of the pulleys. Be careful not to let the door fall while you're removing the cables.
Install the new cables. Feed the new cables through the pulleys, then attach them to the door using the nuts that you removed earlier. Tighten the nuts securely using a wrench.
Reconnect the cables to the door opener. Once the cables are attached to the door, you can reconnect them to the door opener. Use a wrench to tighten the nuts that hold the cables in place.
Test the door. Once the cables are reconnected, test the door to make sure it opens and closes smoothly. If the door is not working properly, adjust the tension of the cables using the turnbuckles located on each side of the door.

Tips

If you're not comfortable replacing garage door cables yourself, you can call a professional for help.
Make sure to buy the correct size cables for your garage door. The cables should be long enough to reach from the pulleys on the door to the pulleys on the opener, plus a few inches of extra length on each side.
When you're tightening the nuts on the cables, be careful not to overtighten them. Overtightening can damage the cables or the pulleys.
