When Mrs. Lawrence from College Station called us, she was in shock. Her garage door had unexpectedly slammed down while she was reversing her car. Luckily, no one was hurt, but the cause was alarming: severely worn-out garage door cables. This situation is more common than you might think and highlights how crucial it is to recognize the warning signs early. Garage door components, including cables, sensors, and openers, all work together to keep your garage door system running smoothly. When one part begins to fail, it can create a domino effect that leads to serious safety hazards.
The Consumer Product Safety Commission reports that over 20,000 injuries occur annually due to garage door accidents. Many of these injuries are tied to cable failures, faulty garage door sensors, or problems with the opener unit. Worn-out cables might not seem like a major concern until they snap or cause the garage door to jam or fall without warning. This not only creates a dangerous situation at home but also jeopardizes the reliability of your entire garage door system.
While garage door sensors are often highlighted as essential for garage door safety, cables are just as important. The cables bear the weight of the door during opening and closing cycles, ensuring that the door moves in a stable and controlled manner. When these cables wear out, they affect the alignment, balance, and overall performance of the door. Let’s take a closer look at the top five warning signs that your garage door cables may be worn out and what you can do to keep your garage safe and functional.
1. Frayed or Rusted Garage Door Cables
Frayed or rusted cables are a clear indication that your garage door system may be approaching failure. Cables are an important part of the door’s lifting system, responsible for bearing a substantial amount of weight. Over time, exposure to humidity, temperature fluctuations, and regular wear can cause the steel strands within the cable to unravel or corrode.
In College Station, TX, our team frequently encounters garages affected by high moisture levels. This often leads to rust developing on garage door cables and other metallic parts. A frayed cable looks like it has thin wires poking out, while rusted cables often have a reddish-brown color or leave behind a dusty residue. These are signs that the cable’s strength is compromised and its ability to support the door is significantly reduced.
The danger of frayed or rusted cables lies in their unpredictability. Even if the garage door appears to be operating normally, the structural integrity of the cables may be compromised. One day, the door may suddenly fail to open or close correctly. In more serious cases, the cables can snap during operation, causing the door to drop suddenly, leading to possible damage, personal injury, or both.
Homeowners should routinely check their cables and look for visible wear and tear. If you notice any abnormalities, it is time to contact a professional garage door technician. Delaying cable replacement can lead to sudden snapping, which may cause the garage door to fall and result in property damage or injury. Ensuring your cables are in good condition is one of the first things you should do when maintaining your garage door system.
2. Slack or Loose Cables Near the Bottom of the Door
Slack in your garage door cables is a serious problem that often goes unnoticed. Cables should remain taut to help the door move evenly and securely. If you see slack or sagging near the bottom of the door, it is an early warning sign of cable stretching or imbalance.
There are a few reasons this may occur. One common issue is the deterioration of the torsion spring system, which works in coordination with the cables. If the spring loses tension, the cable compensates, leading to slack. Another possibility is that one side of the cable has come off the drum or pulley, throwing off the alignment of the entire garage door.
In many cases, homeowners may not even notice the slack until the garage door begins to tilt or open unevenly. An unbalanced door can also put added strain on the garage door opener, forcing the motor to work harder and wear out faster. This can lead to motor failure and costly repairs. Loose cables may also cause the door to bind or drag along the tracks, increasing the risk of the door jamming or becoming misaligned.
A slack cable often causes the garage door to appear crooked or lean to one side. When this happens, the door may also strain the opener unit and reduce the efficiency of your garage door sensors. If you notice slack cables, do not attempt to fix them manually. The tension in a garage door cable system is powerful, and improper handling can lead to serious injury. Always call a professional to inspect the system and restore the correct tension.
3. Jerky or Uneven Door Movement
Garage doors should operate smoothly and quietly. When you start noticing jerky or uneven movements, the cause could be related to your cables. Worn or damaged cables interfere with the door’s balance and prevent it from gliding smoothly along the tracks.
Jerky movement can stem from a few things. One common reason is a cable that is wearing thin in certain sections, causing it to momentarily slip on the drum. It may also indicate that the cable has begun unraveling and is getting caught on other components of the garage door system. This inconsistent operation places additional stress on the opener, sensors, and wiring, which can lead to further issues.
Furthermore, the uneven motion can affect the way the garage door sensors operate. If the door moves irregularly, it can throw off the alignment of the photoelectric sensors that project the infrared beam across the base of the door opening. These sensors are vital for ensuring the door does not close on a person, pet, or object. If they become misaligned due to jerky motion, they may not function properly, leading to serious safety concerns.
For example, if one side of the door moves faster than the other, the infrared beam of the garage door sensor may become misaligned. This misalignment prevents the sensor system from properly detecting objects in the door’s path, compromising garage door safety. In some cases, the door may even come off its track, presenting a serious hazard.
If your garage door exhibits jerky or slow movement, avoid using the automatic opener and switch to manual operation only if it is safe to do so. Call a professional to inspect the cables, opener unit, and garage door sensors to ensure everything is in proper working order.
4. Door Stops Midway or Refuses to Move
A door that stops midway during opening or closing may not always be a sensor problem. While garage door sensors play a critical role in detecting obstructions and preventing injury, mechanical issues such as a tangled or broken cable can also prevent the door from completing its cycle.
This kind of malfunction can be confusing because the garage door sensors, switches, and remote might appear to function normally. However, if a cable comes off the drum or becomes jammed in the pulley system, it can stop the door in its tracks. At this point, continuing to use the opener may cause the motor to overheat or damage other parts of the garage door system.
Cables that are partially frayed may also bind up during operation. This means the cable doesn’t move smoothly on the drum, leading to jerky or inconsistent movement. Over time, this can put strain on the motor and opener unit, eventually causing them to malfunction or fail. The added wear on parts can turn a minor issue into a more expensive and complicated repair.
This issue is more likely in older systems or in doors that haven’t had regular maintenance. One real-world example involves a homeowner whose garage door would not close all the way. Initially believing the issue was caused by dirty lenses on the garage door sensor, they cleaned the sensor but saw no improvement. Upon inspection, our technician found that the cable on one side was jammed under the drum. Once replaced, the door resumed proper function.
If your garage door suddenly stops or behaves unpredictably, do not ignore the signs. This could indicate a deeper problem in the cable system that requires immediate attention to avoid injury or additional damage.
5. Loud Noises or Sudden Door Falls
If you hear a loud bang from your garage, it may be the sound of a cable snapping. This is one of the most dangerous situations you can face with a garage door. A snapped cable causes the entire weight of the door to become unsupported, which can lead to it falling abruptly.
This can happen when worn-out cables are subjected to additional stress, such as during an attempted opening when the door is obstructed. A sudden drop can break parts of the door, damage the garage floor, and potentially harm people or pets nearby. The garage door sensors and opener unit are not designed to handle such force and often get damaged in the process.
The failure of a cable puts tremendous strain on the remaining parts of the garage door system. The springs, opener motor, and safety sensors all experience increased wear. If the opener attempts to raise a door with a snapped cable, it may burn out or seize, creating additional problems. If the garage door sensors detect no obstruction, they may still allow the door to close, potentially compounding the issue.
In one instance, a customer experienced this exact issue when a toy left near the bottom of the door caused the cable to become unbalanced. The cable snapped during the next operation, and the door crashed down. Fortunately, no one was injured, but it was a costly repair.
If you ever hear sudden noises from your garage, stop using the door immediately and inspect the cables from a safe distance. Do not attempt to operate the opener or manually move the door.
