How to Adjust a Double Spring Garage Door

A double spring garage door provides added balance and stability for the door. Over time, these springs may need adjustment to ensure smooth and proper functioning. Here are step-by-step instructions on how to adjust a double spring garage door:

Step 1: Prepare the Tools
Before starting the adjustment, gather the necessary tools. You will need a ladder, winding bars, a wrench, and safety glasses.

Step 2: Disconnect the Opener
To prevent any accidents while adjusting the springs, disconnect the opener from the power source. This step ensures that the garage door remains stationary while you work on the springs.

Step 3: Identify the Springs
Locate the double springs on either side of the garage door. These springs are usually mounted above the horizontal tracks.

Step 4: Determine the Type of Springs
There are two types of double springs: extension springs and torsion springs. Extension springs run parallel to the horizontal tracks, while torsion springs are located above the door, parallel to the ceiling. The adjustment process varies slightly depending on the type of springs.

Step 5: Adjusting Extension Springs
For extension springs, insert the winding bars into the holes on both sides of the spring. Apply force to the winding bars while turning them in a downward direction. This will increase the tension in the springs. Conversely, if you need to decrease the tension, apply force while turning the bars upward.

Step 6: Adjusting Torsion Springs
For torsion springs, use a wrench to loosen the set screws on the spring cones. Once loosened, you can either increase or decrease the tension by turning the cone in the appropriate direction. Turning the cone counterclockwise increases the tension, while turning it clockwise decreases the tension.

After adjusting the springs, manually open and close the garage door to test its balance. The door should move smoothly and stay in position when partially opened. If the door feels heavy or uneven, further adjustment may be necessary.
