What Uneven Cable Tension Looks Like
A garage door relies on two cables working together with a matched pair of springs to lift evenly on both sides. When tension becomes uneven, one side of the door lifts faster or higher than the other, and the panel visibly tilts as it travels up or down the tracks.
Homeowners in Tallahassee, FL often first notice this as a gap that widens on one side of the door frame, a scraping sound against the track, or the door refusing to sit flush against the floor when closed. Left alone, the imbalance puts extra strain on the opener, the rollers, and the remaining cable.
Common Causes of Uneven Tension
Several parts work together to keep both sides of the door balanced, and a problem with any one of them can throw off the tension.
Cables that have stretched over time or developed frayed strands can no longer hold the same tension as the opposite side, causing a visible lean.
Torsion or extension springs wear at different rates, and a weaker spring on one side reduces the lifting force that cable receives.
If a cable drum shifts out of its original position on the shaft, the cable can wind unevenly and change how much tension it carries.
A bent or misaligned track can make one side of the door bind, which puts uneven load back onto the cables and springs.
Loose brackets or fasteners holding the cable system in place can allow small shifts that gradually turn into a noticeable tension gap.
Signs Your Cables May Be Unevenly Tensioned
These are common warning signs homeowners notice before a cable or spring problem becomes an emergency.
What to Do When Tension Looks Uneven
Once you notice a crooked door or a slack cable, here's how homeowners typically approach next steps.
Stop Using The Door
Avoid running the opener while the door is visibly crooked, since continued use can put more strain on the remaining cable and spring.
Note What You're Seeing
Write down which side looks lower, any sounds you're hearing, and when the issue started, since this helps with an accurate diagnosis.
Request A Diagnosis
A trained eye can check the cables, drums, and springs together to identify the actual source of the imbalance rather than guessing.
