But if you’re a do it yourself kind of person we want to make sure you have all the knowledge you need. Let’s get started!

Check Your Garage Door

Lift your garage door up about 3 feet. If it’s hard for you to lift then it’s hard for your opener as well. If the door comes straight down when you let go, or shoots up, you know your springs aren’t working properly and they need to be repaired.


Before we start on how to perform a garage door spring repair, let’s list out all the tools you’ll need.

  • Safety Glasses
  • Winding Bars
  • Vice Grips
  • 9/16 and 7/16 wrench
  • Ladder

Phase 1: Removing The Spring

Always start garage door maintenance by unplugging your opener. The last thing you want is somebody pressing the button while you’re working on it. Then take the red cable coming down and pull it to switch your door to manual mode. Next, use your ladder, winding bar, and 7/16 wrench to loosen the 2 7/16 bolts on the spring. SAFETY TIP: the spring should NOT be beside your head. The spring should be in front of your face.

Now that your bolts are loose use your winding bars to loosen your spring. You’ll be doing quarter turns, and the number of turns is dependent on the height of your door. It’s usually the height of your door times 4 equals the number of quarter turns you’ll need to do. 30 quarter turns is the standard. Now use your 9/16 wrench to remove the 2 9/16 bolts from the center. After you’ve done that you’ll need the 7/16 wrench to loosen the drums on the sides.

Now that everything is loose you can grab the torsion tube (what the spring is on) and shift it over until it comes loose. Once it’s loose, allow it to rest on the j-bar in the center. Now you’re free to remove your bad spring! SAFETY TIP: remove your bad spring from the workplace. It’s easier than you think to accidentally slip on it and hurt yourself.

Phase 2: Replacing the Spring

When doing garage door spring repair, most experts recommend a 2 spring system because it works better and lasts longer, so that’s what we’ll be teaching you how to install today. You’ll notice that the two springs you get will have a red end and black end. The red goes on the left and the black goes on the right. MEMORY TIP: think of a horizontal stop light. The red light is on the left.

Slide the red spring on the torsion tube, then slide on a metal center bearing, and then slide on the black spring. The two springs should meet in the middle at the j-bar. Lastly, slide the drum back on. Now it’s time to put the tension tube back into the bearing plate. Once you’ve done that, make sure the torsion tube is straight all the way across . You’ll also want to make sure it is the same distance from the wall all the way across. This symmetry will help your opener work better and last longer. Now that everything is symmetrical, you can bolt the springs together.

Now it’s time to re-attach the drums. Starting with left drum, go ahead and re-attach the cable to the drum and wind it up. Now, with your left hand, hold down the drum, and with your right hand use the vice grips and attach them to the torsion tube. Make sure the vice grips are resting against the wall. Now you should have tension in your cable all the way to the ground. You’ll want to check the cable to make sure it isn’t caught on anything on the way down the door. With the other drum, hold down the drum with one hand then tighten the bolts. You want tension in the cable on this side as well.

Now it’s time to tighten your springs. Remember, multiply the height of your door by 4 to get the number of quarter turns you’ll need to perform. After you’ve tightened the springs tighten the bolts, remove the vice grips, and your garage door spring repair is almost done!

Phase 3: Quality Check Your Door

Now when you pick up your door it should be light in weight and it should stay wherever you put it. Roll your door all the way up and check the cables at the top. They should be tight. If they aren’t it is a safety hazard because the door could fall while it’s rolling down. Another thing you want to do is make sure the door only opens as much as it needs to. If you have it going 2 feet or so past the opening it’ll wear out your springs faster and you’ll wind up having to go through this whole process again.

Now that everything is set up, you’re free to plug your opener back in. Next, move the red cable to change your opener back to automatic mode. Press the opener button to have the door roll up and you’ll see the trolly connect back in place. Now roll it down and you’re garage door spring repair is complete!
