5 CAUSES OF GARAGE DOOR CABLE FAILURE. Garage doors are an essential part of your home, providing security, convenience, and protection for your vehicles and belongings. However, like any mechanical system, they are prone to malfunction, including broken springs, actuator issues, and myriad other technical challenges. In this article, we will focus on one such issue, namely garage door cable problems.
A part of the counterbalancing systems, cables bear the weight of the door to ensure smooth movement.
For instance, it might be a good idea to determine why the cable on your garage door came off before replacing garage door cables altogether. By identifying the root cause, you will not only resolve the issue but also prevent similar malfunctions in the future and avoid unnecessary expenses.
From a technical standpoint, a garage door system is a combination of components, but in practice, it behaves almost like a living organism. Yet, should some component fail, it might affect the whole system. Hence, if your garage door cable came off, it might be a part of a more complex problem. Let’s consider the top causes of cable slippage or breakage and how to repair a garage door when the cable came off.
WEAR AND TEAR
Though designed for heavy-duty daily use, garage door cables can still wear over time. With years of constant operation, cables can naturally degrade due to consistent friction. If you notice the signs of fraying or damage on the cables, it’s time to get some new ones. Prompt replacement will prevent failure and more serious problems while minimizing the risk of damage to your property or person.
RUST AND CORROSION
Similar to wear and tear, rust and corrosion occur naturally when cables are exposed to high humidity, moisture, or other environmental factors that weaken their structure and compromise their integrity. Applying a rust-inhibiting lubricant is also a sure way to prevent further corrosion.
OBSTRUCTIONS
Beyond natural reasons, the prime cause of why a garage door cable came off the pulley may be some objects or debris blocking the door. Obstructions can cause both cable slippage and tangling, depending on the door type.
One way or another, you should first remove the obstruction from the door track. Then, check the surrounding area to ensure there are no other obstacles that can further impede the door movement.
However, if your situation is as bad as the one in the image above, it might be time to call for professional repair service.
IMPROPER INSTALLATION
Incorrect installation of the cables or improper tensioning can lead to premature failure. If the garage door cable came off one side, you should check whether tension is even in both drums to avoid the cable unwrapping.
The same is true for misaligned tacks that can cause uneven tension on the cables, leading to excess wear.
You can also install a special retainer at the bottom of the garage door to compensate for the uneven installation surface.
WRONG CABLES
If adjusting the tension is not enough to fix a garage door cable that came off the pulley, the problem might be in the cable itself. Cables for garage systems vary by type, diameter, and length.
Notably, different types of drums are compatible only with specific cable types and sizes, as well as track configurations. If there is a mismatch, it can be the reason your garage door cable came off the drum.
Similarly, using the wrong cable strength can cause cable assembly failures and breakage. In simple words, if you use thinner cables with heavier doors, they won’t stay with you for long.
Choose cables that are compatible with your specific garage door model and weight requirements, and consult a specialist when in doubt.
