Understanding Garage Door Springs and Cables
Mechanism and Types of Garage Door Springs
Garage door springs are essential components responsible for counterbalancing the weight of the door, making it effortless to open and close. They are commonly found in two types:
* Extension Springs: Mounted horizontally above the door, these springs stretch when the door is lifted and contract when it is lowered.
* Torsion Springs: Installed within the horizontal shaft above the door, these springs twist when the door moves, storing energy to assist in lifting the door.
Spring Strength Variations
Garage door springs vary in strength, denoted by a color-coded system:
| Color | Spring Strength |
|---|---|
| Red | Strongest |
| Green | Medium Strength |
| Yellow | Lightest |
Matching the spring strength to the weight of the door is crucial for optimal performance. Using a spring too weak can impair the door’s ability to lift, while a spring too strong can cause premature breakage.

Tightening or Loosening Cables
Locating the Adjustment Points
Identify the two sets of cables that run from the bottom corners of the door to the sides of the opener. Each cable has a turnbuckle or eyebolt adjustment point near the opener.
Measuring Cable Tension
Before adjusting, measure the distance between the bottom corner of the door and the bottom bracket of the opener. This distance should be equal for both sides.
Tightening the Cables
To tighten the cables, turn the turnbuckle or eyebolt clockwise with a wrench or pliers. Tighten the cables gradually, checking the door tension after each adjustment. Avoid overtightening, as this can damage the cables or opener.
Loosening the Cables
To loosen the cables, turn the turnbuckle or eyebolt counterclockwise. Loosen the cables gradually, again checking the door tension after each adjustment. Avoid under-tightening, as this can cause the door to sag or bounce.
Balancing the Cables
Once the cables are tightened or loosened, balance the door by adjusting the length of each cable. Adjust the length of the cables until the distance between the bottom corner of the door and the bottom bracket of the opener is identical on both sides.
Testing the Door
After adjusting the cables, test the door to ensure it operates smoothly. Open and close the door several times, checking for any binding or bounce. If the door is not operating properly, re-adjust the cables as necessary.
