Replace Cable On Garage Door

A garage door cable is an essential component that helps to open and close the door smoothly and safely. Over time, cables can become frayed or damaged, which can lead to problems with the door's operation. If your garage door cable is damaged, it is important to replace it as soon as possible to prevent further damage to the door or injury to yourself or others.

Replacing a garage door cable is a relatively simple task that can be completed in a few hours. However, it is important to follow the manufacturer's instructions carefully to ensure that the cable is installed correctly. Here are the steps on how to replace a garage door cable:

1. Safety First

Before you begin working on your garage door, it is important to take some safety precautions. First, disconnect the power to the door by flipping the breaker or unplugging the opener. Then, lower the door manually to the closed position and engage the lock.

2. Remove the Old Cable

Once the door is secure, you can begin removing the old cable. Start by loosening the bolts that attach the cable to the bottom bracket of the door. Then, slide the cable out of the bracket and pull it through the pulleys at the top of the door. Finally, detach the cable from the spring tensioner.

3. Install the New Cable

Now that the old cable is removed, you can install the new cable. Start by threading the cable through the pulleys at the top of the door. Then, attach the cable to the spring tensioner and tighten the bolts. Finally, slide the cable into the bottom bracket of the door and tighten the bolts.

4. Adjust the Cable Tension

Once the new cable is installed, you will need to adjust the cable tension. Start by loosening the locknut on the spring tensioner. Then, turn the tensioner bolt until the cable is tight. Be sure not to overtighten the cable, as this can damage the door. Once the cable is tight, tighten the locknut.

5. Test the Cable

Once the cable tension is adjusted, you can test the cable to make sure it is working properly. Reconnect the power to the door and open and close the door a few times. If the door opens and closes smoothly, the cable is installed correctly.

6. Lubricate the Cable

To keep your garage door cable in good working order, it is important to lubricate it regularly. Use a spray lubricant and apply it to the cable every few months. This will help to prevent the cable from rusting and fraying.

Conclusion

Replacing a garage door cable is a simple task that can be completed in a few hours. By following the steps above, you can ensure that the cable is installed correctly and the door is operating safely.
