    Steps In Replacing Garage Door Cable

    You can always do DIY but, we don’t recommend it.

    It’s better to rely on a professional garage door technician for your safety.

    That’s because you might hurt yourself during the project.

    However, we will still give you ideas on how to replace a garage door cable to give you an idea.

    These steps will help you do your project.

    Pull Out The Release Handle

    The first step is to disengage and unplug your automatic door opener by drawing out the backup release handle.

    This handle has a red cord that is found close to the opener or at the utmost rail.

    It will enable you to lock or unlock the garage door manually.

    Open And Hold The Garage Door Using A Vice Grip

    After you manually open the garage door, get a vice grip and use it at the automatic door roller on each side.

    It would hold the door while you’re replacing the garage door cable.

    Untighten The Screws

    The third step is to go to the automatic door and untighten the bunch of screws on the spring.

    Also, take note that you should completely insert the winding bars and use each of them to avoid accidents.

    After you’ve inserted the winding bars, keep on unwinding your automatic door spring until you remove all the tension.

    However, if your door has two springs, repeat the process, but this time around, do it with the second spring.

    Disengage The Screws On The Cable Drum

    After you remove all the tensions from the spring, get your wrench and disengage the screws from the cable drum.

    You can find the cable drum at the top left of the garage door.

    Right after you loosen the screws, pull out the cable from the cable drum.

    The next thing you should do is get the socket and ratchet, then dismantle the lag screw from the jammed bracket.

    After that, remove the lower bracket and pull the cable.

    Installation Of New Cable

    After you’ve done the previous steps, you can now move to the installation process.

    Get your new cable and install it at the bottom bracket.

    Tighten the cable until you reach the cable drum.

    Take note to do this on both sides of the garage door.

    Now, place the cable into the cable drum.

    Ensure that it is correctly installed and doesn’t overlap into the cable drum. After that, roll the cable onto the cable drum, and turn in a counterclockwise direction.

    Repeat this process until the cable is secured.

    After you complete all the steps, increase the tension on your spring through your winding bars.

    Final Step

    Safely remove the pliers from the metal rod, and reconnect the door by dragging down the backup handle.

    After doing that, you can now plug in the door opener.


    Take note that replacing a garage door cable is complicated, and you should safely follow this guideline to avoid accidents.

    It’s best to leave this job to an expert.
