The cable is the most crucial part of your garage door. It controls the pulling up and down of the door. It also functions as a backup, when the spring recoils violently. The reason why the door cable of your garage may breakdown is because of bad bearings, worn out parts and poor adjustments. If your garage door feels heavier than usual, it may be because of a broken cable or a spring. Therefore you need to keenly access your door to find out if it’s either of the following:
- Loose Cable Adjustments
If the issue is just a slip of the cable off the pulley system, you can put it back in place. Use the pliers to relax the bracket and then pull the loose cable through the bracket and tighten it up.
- Worn-out Cable or Pulley System
Where the cable stops to function due to tearing and wearing out, or it is broken. You will need to replace it immediately with a new one.The pulley also may be worn out, preventing the cable from gliding easily, thus making the door incline on one side. In this case you will need to replace the pulley system.
Leaving it unrepaired can cause more damage to the entire garage door system or damage your car or other things in the garage. Worst case scenario, it may cause life threatening accidents and bodily harm to your family members or yourself.
You will require the following tools;
- Vise grip or locking pliers
- New cables
- Winding bars
- A ladder
- A pair of gloves, and
- Safety glasses
Here are the steps to guide you in replacing the door cable of your garage:
- Disconnect the door opener from an electric outlet and remove arm from the opener.
- Lock and clamp door closed using vise grip tracks.
- Undo all the springs and keep you face away from the winding cone.
- Loosen the drum and remove the cable from the cable drum.
- Loosen the track and remove the bottom bracket and free the cable from it and remove the cable from the door. Attach the new cable into the bottom bracket and reinstall the fasteners and tighten them up. Place back the bracket to its original position.
- Mount the cable in the drum, while ensuring it runs freely from the bottom brackets. Ensure the cable is well fixed on the cable drum and then you can gently tighten the screws on the cable drum.
- Slip the winding bar inside the cone and wind it upwards. Fasten up the brackets and tighten the bolts. After both cables are installed and both cable drums are tightened down, you can release tension on the torsion spring.
After you are done, you can now test the garage door manually. This is to ensure that the cable is winding up on the drum and is not missing the ruts. Open and close the door slowly a few more times to test whether it is gliding smoothly. You can then test the opener automatically by connecting to the power outlet.
