How to Fix Cable on Garage Door

Why It’s Important to Fix the Cable on The Garage Door?

It’s important to fix the cable on the garage door because a broken or loose chain can cause the opener to work harder than necessary, which can shorten its lifespan. If the cable breaks, it can also cause the door to come crashing down, which can be dangerous. So if you notice that your garage door opener is having trouble moving the door up and down, or if you see that the chain is loose or damaged, it’s time to fix your garage door.

What You’ll Need:

Phillips Head Screwdriver:

You’ll need this to loosen and tighten the screws on the garage door opener. Make sure to choose the right size for your specific opener.


Pliers will come in handy when working with cables and springs. They can also be used to adjust tension.

Wrench Set:

A wrench set will be needed to tighten any loose bolts or nuts on the garage door opener or tracks.

Replacement Cable:

If your cable is damaged or broken, you’ll need to purchase a new one before starting the repair process.

How to Fix Cable on Garage Door Step-by-Step Guide

Step 1: Lock Down the Door:

The first step is to lock down the door. This is done by closing the garage door and then pulling the red cord above the door. This will release the lock and keep the door closed. You may need a ladder to reach the cord. It’s important to make sure the door is securely locked down before starting any repairs.

Step 2: Loosen the Unbroken Spring:

If the broken cable is on the left side of the garage door, you will need to loosen the unbroken spring. This can be done by turning the adjustment bolt clockwise at the end of the spring with a wrench. Be careful not to over-tighten the bolt, as this could cause damage to the spring.

If the broken cable is on the right side of the garage door, you will need to loosen the unbroken spring by turning the adjustment bolt located on the end of the spring counterclockwise with a wrench. But, again, be careful not to over-tighten the bolt.

Step 3: Unwind the Unbroken Spring:

Assuming that the cable is still attached to the garage door and that it has not broken, you will need to unwind the unbroken spring. Then, use your hands to slowly turn the winding cone on the end of the spring in a clockwise direction. You must take your time with this step, as you do not want to damage the spring.

Step 4: Disconnect the Springs from The Center Bracket:

There are two springs located on the center bracket. You’ll need to remove the nuts that hold them in place to disconnect them. You can use a socket wrench for this step. Once the nuts are off, you can pull the springs off the bracket and set them aside. Be careful not to let them snap back and hit you.

Step 5: Secure the Torsion Tube:

Now, it is time to secure the torsion tube. This can be done with either the clips with your door or cable ties. If you are using cable ties, make sure that you do not overtighten them, as this can cause damage to the door. Once the tube is secured, reattach the opener arm. The tension from the springs will help hold everything in place.

Step 6: Remove the Old Spring:

There are two springs on the garage door, one on each side. The spring is located between the cable and the roller. To remove the old spring, you will need to loosen the set screws that hold it in place. Once the screws are loosened, you can pull the spring out of the bracket. Be careful not to let the spring snap back.

Step 7: Buying Replacement Parts:

If you have determined that the cable is the issue, you will need a replacement. You can find these at most hardware stores or online. The type of cable you need will depend on the make and model of your garage door. Be sure to get the right size and type to avoid further issues. But, if you are unsure, it is always best to consult a professional.

Step 8: Install the Left Spring:

Install the left spring onto the shaft. The coil should be facing down. The end of the spring with the hook should be on top of the garage door. Slide the spring up the shaft until it is seated against the bearing plate. You will need to wind the spring a certain number of times, depending on the size and weight of your garage door. Be sure to follow manufacturer instructions or consult a professional if you are unsure.

Step 9: Install a New Center Bearing:

Garage door cables can often break or fray at the bearing plate. If this is the case, installing a new center bearing is important. You’ll need to remove the bottom bracket from the door to do this. Once this is done, you can install the new bearing and replace the bracket. Ensure the bracket is securely fastened before moving on to the next step.

Remove the Cables

Step 10: Replace the Bottom Brackets, Rollers, and Lift Cables:

Again, use the adjustable wrench to unscrew the bolts that secure the bottom brackets to the garage door. Next, remove the brackets and rollers, then replace them with the new ones. Be sure to insert the screws in the correct holes, as they may be a different color than the old ones. Finally, reattach the lift cables to the bottom brackets and rollers.

Step 11: Thread the Cables:

If your cables are frayed, it’s time to replace them. You’ll first need to remove the drum from the shaft to do this. Once the drum is off, you can start threading the new cables through the holes in the bracket and around the pulleys. Ensure that the cables are evenly spaced on each side of the door. Once the cables are in place, reattach the drum to the shaft and test the door.

Step 12: Tighten the Drums:

Now that the cable is in place, it’s time to tighten the drums. To do this, you’ll need a crescent wrench. Place the wrench on the bolt and turn it clockwise until it’s tight. Do not over-tighten the bolts, or you could damage them. You may need to use a second wrench to hold the shaft in place while tightening.

Step 13: Wind the Garage Door Tension Springs:

Wind the garage door tension springs by turning them clockwise. Be careful as they are under a lot of tension. It would help if you had someone help you with this step to ensure your safety. Once the springs are wound, stop and check to ensure the cable is in place and tightened. If it is not, repeat steps 10-12 until it is.

Step 14: Stretch the Springs:

With the door in the open position, use a broomstick or other long object to push down on the garage door opener lever. This will stretch the springs and help take some of the tension off of them. Be careful not to let go of the opener lever while stretching the springs! It could cause damage or injury.

Step 15: Lubricate the Spring:

This will help keep the door working correctly. There are special lubricants made specifically for garage doors, but you can also use a silicone spray.

If your garage door is old, it may be time to replace the cables. This is a job that should be done by a professional, as it can be dangerous if done incorrectly. If you decide to replace the cables yourself, make sure you have the correct size and type of cable.

It is also a good idea to keep your garage door properly lubricated and in good condition to avoid any problems in the future.

When installing the new cable, follow the manufacturer’s instructions carefully. If you are not comfortable doing this yourself, call a professional to help. Replacing a cable can be a dangerous job, so please call a professional if you are not comfortable with it. Keep reading for more information about how to fix cable on garage door.

Some Other Ways to Replace a Garage Door Cable?

If your garage door cable has snapped, it will need to be replaced as soon as possible. This is a job that can be done by most people, provided they have some basic tools and know-how. The following steps will show you how to replace a garage door cable:

1. Switch Off the Power:

Before you do anything, you will need to switch off the power to the garage door. This can usually be done by flipping a switch in the garage or pulling out a fuse in the box.

2. Remove the Manual Lock:

Some garage doors have a manual lock that you will need to release before the door can be opened. So first, find the manual lock and release it. This is usually done by pulling on a lever or turning a knob.

3. Hold the Door:

Now, it’s time to hold the door. This is where you use your body weight to keep the door closed. Again, you will need someone to help you with this step. One person should be on each side of the door and put their hands on the door near the bottom. The person on the inside then pushes up on the door while the person outside pulls down. This will keep the door in place while you work on the cables.

4. Remove the Springs:

The springs are another common source of problems with garage doors. They can become worn out or damaged, which will make the door difficult to open and close. If you suspect that your springs are causing issues with your door, you can remove them and inspect them for damage. If they are damaged, you can replace them yourself or call a professional to do it for you.

If you will remove the springs, be sure to take precautions. The springs can be hazardous if they are not appropriately handled. Be sure to wear safety goggles and gloves, and use caution when handling them. Once you have removed the springs, you can take them to a hardware store or garage door specialist to have them replaced.

5. Remove the Cables:

Once the opener is exposed, it is time to remove the cables. This can be a little bit tricky, as the tension on the cable will be high. You will need to use a socket wrench or crescent wrench to loosen the bolts that hold the cable in place. Be very careful when doing this, as one wrong move could result in the cable snapping.

7. Test the Door:
