How to Repair a Garage Door: Springs and Cables

Before you start, you should know that no one can repair garage door springs and cables. In fact, there are cases where you will need a professional to take care of the job. However, if you follow these garage door repair instructions, you shouldn't have a problem.

How to Repair a Garage Door

You will need the following tools and materials:

•  Hammer
•  Clamps
•  Protective equipment such as safety glasses and leather gloves.
•  Set of keys with an adjustable wrench
•  Drill
•  Locking pliers
•  Winding bars
•  Set of socket wrenches and ratchet
•  Lifting cables
•  Torsion springs
•  Lower supports

Please note, this is for rebuilding your torsion spring system and not for replacing your garage door springs. Also, you need to find out how much you will save by doing these kinds of activities yourself.

There are cases where you will not save a lot of money. For this reason, we encourage you to always do some basic research before even starting work. That way, you can tell the difference between the cost of repairing a professional garage door and doing the project yourself.

We will go over each of these.

Step # 1: Lock the garage door and loosen the intact springs

You will first start by holding the garage door in place with the pliers and locking clamps. This is to help prevent any accidents that might occur due to an open garage door.

Then, using your winding bar, you will loosen the good spring. Place it on the winding cone and begin loosening the set screws. Be careful, as the spring can turn aggressively when loosening.

Step # 2: Unroll and Disconnect the Springs from the Center Bracket

Using a second winding bar, place it into the next hole, making a nearly 90 degree angle between the winding bars. After that, remove the first winding bar and turn the spring. Do this by hovering over the movement.

Remove the bolts and nuts that are on the stationary cones. After that, try to slide the springs to the supports that are at the end.

Step # 3: Secure the torsion tube and remove the old springs

Use your locking pliers to loosen the set screws found on the left and right light cable drums. Then disconnect the cables.

When you're done disconnecting the cables, start on the left side of the door by sliding the torsion tube to the right. That way, you can remove the cable drum. Lastly, you can pull the broken spring out of the tube.

Step # 4: Install the New Center Bearing and Left Spring

First, you will need to reassemble by sliding the replacement torsion spring onto the tube. Note that during this step, you will need to have the cone fixed facing the center support. After that, you can install the cable drum again and reinsert the torsion bar.

Second, you will need to connect the stationary cones to the bracket by sliding the center bearing over the torsion bar.

Step # 5: Replace the rollers, lifting cables, and bottom brackets

This is the perfect time to change rusty rollers, cables, and bottom brackets. You can do this by first placing the lift cable loop on the new bottom bracket.

Step # 6: Thread the wires and tighten the drums

Lastly, you will need to secure the lift cable in the cable slot. Also, remember to tighten the drums with the pliers. After that, it's time to roll up the wire, tightening as much as possible before putting in the set screws.

Lastly, you'll want to make sure that both sides of the garage door are tight equally. That way, your door will open properly and evenly.
