Just like everything that deals with tension, garage door cables can snap or get damaged over time. And when they do, the door opening mechanism will not work at all. Well, we had failed garage door that needed a cable replacement, but we did not know how to replace garage door cable.
Even though there are plenty of guides out there, they make the task seem harder than it is. So, we got into experimenting. After trials and errors, we did manage to learn the simplest way. And through this article, we plan to make the whole replacement job easier for you by explaining the entire process.
Steps to Follow to Replace Garage Door Cable
We aim to make more complex tasks feel simple by avoiding unnecessary hassles. And this guide will precisely help with that. So, without further ado, let us get into explaining the steps, shall we?
Step 1: Get the Necessary Materials
First and foremost, you need to gather the things required for carrying out the project. Here is the list:
Step 2: Disengage the Old Garage Door Opener
After gathering the necessary materials, you should unplug the garage door opener. That will disengage the whole mechanism. You can do it by pulling on the emergency release handle. Cannot find it? It is usually a red rope that comes with a handle. This handle should be located right beside the opener or the top rail.
Step 3: Use the Vice Grip
You need to open the door and place the vice grip just below the garage door roller. Please put it in such a position that it makes contact with both sides and holds the door for you while replacing the cables.
Step 4: Loosen the Screws
Move your focus to the center of the door and loosen the screws that are on the springs. They should require ¼ turns. You would need to insert the winding bars in this case. And to prevent any injury, make sure you use both the bars and move away from the bars after placing them.
Do not give up on unwinding the door spring. Continue unwinding up until the point where all of the tension is removed. Repeat the process if there are two springs present on your door. You can use a lubricant for garage doors, to have a smooth ride.
Step 5: Work with the Cable Drum
Next, you need to move on with the cable drum. Usually, the drum will be on the top left of the door. Loosen the screws and remove the cable. Take the ratchet and sockets and remove the screws from the jamb bracket. Also, take your time to remove the bottom bracket and remove the cable entirely.
Step 6: Place the New Cable
Now that the old cable is off place the new cable inside the drum. It should fit right into the slot and thread it in place. Make sure that you follow the process on both sides. While placing the cable, ensure that it does not overlap.
Then, work on winding the cable onto the drum. Slide the drum over the plate of the bearing and rotate it. You would need to turn it counterclockwise. Turn it to the point where the cable is set in place and is tight. Install the screws that were taken off the drum. Make sure not to overtighten, or the threads will get damaged.
Step 7: Adjust the Tension of the Springs
Hold the cable in place and use the vice grip pliers. Hold the pliers right to the metal rod that usually goes through the door and is against the wall. Please do it for the other side of the door too. After that, you will need to use the winding bars to increase the tension of the springs.
However, do ensure that you are not overwinding the springs. It is possible to increase the tension to ¼ turns only. If you turn it more than that at a time, the springs can get damaged.
Step 8: Carry out the Final Steps
After following all of the steps above, you need to remove the locking pliers off the metal rod. Ensure that the drums are at the correct position, all of the screws are in place, and have the right tightness.
Re-engage the door using the emergency release handle. Pull it down and lift the door until the point you hear a double click. Finally, plug the opener back in place and enjoy smooth garage doors again.
As you can see, learning how to replace garage door cable is not rocket science. All you need to do is follow the right steps, and you end up with a smoothly functioning door once again!
