How to Replace a Garage Door Cable
Garage door cables are essential for the safe and smooth operation of your garage door. Over time, cables can lose their function due to rust, wear, or damage. The most common causes of cable failure include:
Rusted or snapped cable loops
Cables popping out after a broken garage door spring
Stuck bearing plates causing cable misalignment
Safety First
Warning: Replacing garage door cables involves high tension. Do not attempt repairs unless you have the proper tools, experience, and safety equipment.
Steps to Replace a Garage Door Cable
Secure the spring shaft – Use a locking plier to prevent the shaft from rotating. Alternatively, fully release spring tension by unwinding all springs.
Remove the old cable – Unscrew the cable drum and release the cable if it isn’t already loose.
Detach the bottom bracket – If the cable loop is still attached to the bracket bolt, unscrew the bottom bracket to remove the cable loop easily.
Install the new cable – Place the new cable loop onto the bracket bolt and reattach the bottom bracket to the garage door.
Route the cable – Run the cable along the vertical garage door track up to the cable drum. Ensure there are no obstructions or snags.
Attach to the cable drum – Insert the cable head into the drum and rotate the drum to tighten the cable.
Secure the drum – Once the cable is straight from bottom to top, tighten the drum screws.
Repeat for the other cable – Follow the same process for the second cable.
Rewind the spring – If you released the spring tension earlier, wind the spring back and remove the locking plier.
Congratulations! Your garage door cable replacement is complete.
