Garage door maintenance isn’t just about keeping things quiet—it’s about keeping your door safe, balanced, and reliable every day. One of the most overlooked parts of a maintenance visit is checking and testing cable tension. In this video, we focus on cable tension testing, what it tells you about the condition of your system, and why an issue that looks “small” can quickly become a bigger repair.
At Garage Doors Pro Service, we help homeowners and businesses in Dallas, TX inspect and maintain garage doors so they operate smoothly and safely. Because the cables work together with springs and drums under high tension, cable problems should always be handled carefully and diagnosed correctly.

Why garage door cable tension matters
Your garage door lifting cables carry the door’s weight as it opens and closes. They wrap around cable drums near the top of the door and connect at the bottom brackets. When tension is correct on both sides, the door lifts evenly, stays aligned in the tracks, and reduces strain on other components.
When tension is uneven, you may experience:
– Uneven lifting (one side rising faster than the other)
– Jerky movement or binding in the tracks
– Excess noise during opening or closing
– A door that appears crooked when partially open
– Cables that look slack, loose, frayed, or mis-wrapped on the drum
Cable tension issues frequently show up along with other wear items—rollers, bearings, drums, and sometimes the springs themselves. Ignoring the symptoms can lead to the door coming off track or to accelerated wear on the opener.
Common signs your garage door cables need attention
While a full inspection is the best way to confirm what’s happening, these are typical red flags:
1) Slack or loose cable on one side
If one cable appears looser than the other when the door is down, it may indicate the cable has slipped on the drum, has been incorrectly wound, or the system is out of balance.
2) Door looks uneven or “racked”
A door that looks tilted in the opening often points to uneven cable tension, track issues, or misalignment that should be corrected before damage spreads.
3) Fraying or visible wear
Frayed strands are a serious warning sign. A cable failure can happen without much notice once fraying progresses.
4) Opener strain or reversal
If your automatic opener strains, stops, or reverses unexpectedly, the door may not be moving freely or evenly. Cable tension problems can contribute to this.
What “testing cable tension” means during maintenance
Cable tension testing is not about guessing—it’s about assessing whether both sides of the door are lifting evenly and whether cables are properly seated on the drums.
During a professional inspection, a technician may:
– Visually compare left and right cable tightness
– Check that cables are correctly seated in the drum grooves
– Look for signs of slipping, mis-wrapping, or drum wear
– Confirm the door is level as it travels
– Evaluate overall door balance and spring performance
– Inspect bottom brackets, fasteners, and track condition
Because cables and springs are part of the counterbalance system, an apparent “cable issue” may actually be a spring balance problem (or vice versa). Proper troubleshooting identifies the root cause before making adjustments.
Why DIY cable adjustments can be risky
Garage door cables operate alongside springs that are under significant tension. Adjusting cables without the right tools, training, and safety practices can lead to sudden movement of the door or components, causing serious injury or property damage.
If you notice slack cables, fraying, or uneven lifting, the safest approach is to stop using the door and schedule service. A professional can secure the door, relieve tension safely when needed, and correct the setup.
How routine maintenance helps prevent cable problems
The best way to avoid cable failures is to catch issues early. A maintenance visit typically includes a broad safety check that can identify wear before it turns into downtime.
Key benefits of routine garage door maintenance include:
– Smoother door operation and quieter movement
– Reduced wear on springs, drums, rollers, and opener
– Improved safety by spotting fraying cables or loose hardware early
– Fewer unexpected breakdowns
– Longer lifespan for the entire system
