First, Identify the Signs That Indicate You’ve to Reattach the Cable


Garage doors usually work silently, but sometimes things go wrong, like when a cable needs fixing. Here are signs your garage door cable needs help:

  • Uneven Movement: Does your garage door wiggle or lean to one side? That’s a sign something’s off.
  • Loose Cable: If you see a cable hanging down from the side of your garage door, it needs attention.
  • Door Off Balance: When your garage door doesn’t stay level, it might be because a cable isn’t doing its job.
  • Grinding Noise: If your garage door makes a grinding sound, it might be because a cable has come loose and is rubbing against the tracks.
  • Immobile Door: Is your garage door stuck and won’t budge? This could happen if both ends of the cable are disconnected.

Why Cables Come Loose

Think of your garage door cables like the biceps of your door—they do a lot of heavy lifting. Over time, they can wear out due to:

Wear and Tear: The constant opening and closing can cause the cable to slip off the drum or pulley (the wheel that guides the cable).

Rust: Moisture and rust can weaken the cables.

Poor Installation: Sometimes, it’s just bad luck from the get-go.

Alright, so your garage door cable now needs a pep talk, and you’re up for the challenge. Here’s how to reattach it like a DIY pro:

Step 1: Gather Your Tools

So, how do you put a cable back on a garage door? Before starting the process, you’ll need:

  • Safety glasses to protect your eyes.
  • Gloves to shield your hands.
  • Stepladder for reaching high areas.
  • Socket wrench (size may vary depending on your garage door opener).
  • Pliers.
  • Replacement cable (if needed).

Step 2: Disconnect the Power and Secure the Door

Disconnect the Power and Secure the Door


First things first, turn off the power to your garage door opener. You can usually find a switch on the opener unit itself, or you might need to flip a breaker in your home’s electrical panel. Safety is a must! 

Then, lift your garage door manually and make sure it stays open by using a clamp or pliers. Definitely, you’ve have to follow the right technique when lifting the door manually. 

  • First, before lifting, clear any objects in the way. 
  • Then, you should bend your knees and use your legs to lift, not your back, to avoid strain. 
  • Lift slowly and steadily; use a clamp or pliers to keep it open safely.
  • If the door is heavy or damaged, ask for help. 

Step 3: Loosen the Set Screws on the Cable Drum

Here’s how to replace a broken garage door cable. First, look for the metal cable attached to a round thing above the door called the cable drum (usually at the top of the garage door opener) and pulleys (wheels that guide the cable along the track). 

You might see one or two cables, depending on your system. If you find out that the cable is simply off the drum, loosen the set screws. 


There will be small screws on the drum holding the cable in place. Use your socket wrench to loosen them slightly.

Step 4: Realign the Cable on the Drum

Carefully put the cable back into the slot on the round part above the door called the cable drum. Make sure the cable sits flat and tight in the slot. This is really important so the cable can move smoothly when the door goes up and down.

Step 5: Tighten the Set Screws

Once the cable is in place, tighten the screws snugly with the wrench. Don’t overtighten, or you could damage the drum.

Step 6: Check the Alignment of the Pulleys

Down near the bottom corners of the door, you’ll find these pulley things. Check that the cable moves through them smoothly, without getting stuck or twisted. 

So, to check if the cable moves smoothly through the pulleys:

  • Gently pull the cable with your hand. It should slide through the pulleys without getting stuck or twisting.

If you notice any issues:

  •  Use your fingers to guide the cable so it sits straight within the pulleys.
  • Then, check if the pulleys are aligned properly. If not, loosen the bolts holding the pulley in place, adjust its position slightly, and then tighten the bolts securely. This helps the cable move freely and keeps the door operating smoothly.

 Consult your garage door opener’s manual for specific instructions on pulley reattachment.

Step 7: Test the Door

Test the Door


Time to test it out! First, carefully remove the clamp or locking pliers which were holding the door open. Then, test the garage door by slowly lowering it and then opening it again. 

Watch and listen for any strange movements or noises. The door should move smoothly without any issues.

Step 8: Reconnect Power

Once everything’s working as it should, you can turn the power back on to your garage door opener. Use the remote to operate the door and observe its movement. 

If the door seems uneven, you might need to adjust the cable tension slightly by following your opener’s manual instructions.

Feeling Uncomfortable?

If you’re unsure about any of these steps, don’t hesitate to contact a pro garage door repair service. Their expertise can make sure that your door is fixed safely and functions properly.

How to Open Garage Door When the Cable is Broken?


It’s dangerous to open a garage door with a broken cable. Call a professional or use the emergency release cord (if your model has one) to disengage the opener and lift the door manually.

Any Preventive Tips to Avoid This Problem?

Absolutely, here are some tips to follow:

Regular Maintenance:

  • Every few months, look closely at your garage door cables for wear, like fraying or rust.
  • Lubrication is a must. Follow your garage door opener’s manual to oil the parts that move (hinges, rollers, tracks). This will stop friction and help cables last longer.
  • Remove any dirt or stuff that could tangle the cables or block them from moving smoothly.

Door Balance:

  • Test your garage door by lifting it halfway manually. If it stays where you leave it, it’s balanced. If it leans to one side, you might need to balance it. Check your garage door manual or ask a professional for help.

Professional Check-Ups:

  • Consider having a garage door expert inspect your system once a year. They can find issues early and make sure everything works safely and well.
