How to Adjust Garage Door Cables – A Guide

One of the vital parts needed for the safety of a garage door is the cables that help in the movement of the doors. Garage door cables carry the weight each time you lift the door up or lower it down. They balance the weight of the garage door by holding the tension in the torsion springs on which they run.

Apart from this, the garage door cable steps in when the spring breaks and there is recoil. Without the cable, your springs may fly or fall off and the door may come crashing down suddenly.  Avoid these mishaps by maintaining the cables of your garage door from time to time.

The experts at Thrifty Garage Door are good at adjusting your cables with perfection and precision. Here are a few more things to know before you adjust a garage door cable.

7 Steps to adjust your garage door cables

If you are a DIY person and want to adjust your garage door cables on your own, here is how you should do it.

  • Set up your tools

You would need a step ladder, 2 C clamps, screwdriver with a flat head, pliers, wire cutter etc.

  • Get the garage door ready for work

To do this, pull the rope attached to the door opener. This will release the door opener from its drive chain. Now, the garage door is ready for lowering. When you lower the door, you will see that there is tension in its springs. Release this tension by lifting the door.

  • Fix your garage door in place using C clamps

Fix  2 C clamps to the track of the door beneath the rollers. These clamps will hold the door in place while you work. If you do not fix the clamps, the door might come crashing down.

  • Disconnect the cable

The cable runs across a frame around the garage door. One end of it is fitted to a spring or hook attached to a frame near the doorway. The other end is wrapped on the rollers.

Disconnect the wire which you can see in the frame with holes. Now you will reconnect this wire to one of the holes so that the wire is not loose.

  • Loosen the brackets

Next, use pliers to loosen the brackets holding the wire. Now, you can pull the cable wire through this and tighten it. While doing this, be careful not to loosen the bracket fully as this might tangle the cables.

  • Adjust the cable tension

Loosen or tighten the cable wire to adjust ist tension. Reattach the wire to the frame using the hook. Test the working of the garage door and adjust the cables accordingly. Too much loosening or tightening will not do. This garage door cable adjustment has to be done accurately.

  • Final checks

Check the drum where the cable is wrapped to check the balance of the garage door. See if the cable is wrapped neatly around the drum and if both sides are aligned. Now, remove the clamps and plug the opener. Test the garage door for its smooth operation. Your garage door is now good to use.
