Tension is applied via torsion springs to cables, which roll on the circular spools known as drums. In case you have ever looked at the garage door and seen cables not under the tension you might have off drums garage door cables. Why do the garage door cables go off drums? Mostly cables slip because of natural causes such as wear and tear, whereas other times it’s the result of inappropriate garage door maintenance or operation. The cables are under lots of tension. Never try to fix garage door cables that have moved off drums unless you’re a certified garage door repair technician. Below are some possible reasons for your cables to slip off drums.

BROKEN TORSION SPRINGS
On the garage doors with one torsion spring only, a broken spring can removes tension on cables. This will generally make the garage door to slam on ground unwinding the garage door cables. As torsion springs break down at nearly 10,000 cycles, it’s one among the most recurrent causes of cables going off drums. Try to have 2 torsion springs installed always on every door. In case, one spring breaks down, other spring can easily support the garage door until it is repaired by an expert garage door repair technician. This removes the possibility of garage door getting damaged from aggressively slamming to ground.

IMPROPER SPRINGS TENSION
Installing incorrect torsion spring on your garage door can even cause the cable to slip off drums. If springs are very powerful based on the door weight and size, cables will loosen and pop off drums. If the springs are not strong enough, then the garage door will be solid at bottom and weak on the top causing cables to loosen when the garage door is open. The back-wound springs also will make cables to slip. In addition, applying tension to springs in wrong direction during their installation will also throw the cables.

DOOR SET ON ANY OBJECT
The most frequent user error for cables to go off drums is setting the garage door on something. Many times, bumper of an automobile or chair might stick over the door opening without even triggering the photo eyes safety reverse features. When this occurs, the weight of door is distributed unevenly, leaving slack in cable on one side. Always ensure that no object is there in the door’s opening before trying to close your garage door ever.

CABLE SNAPPED
Frayed and rusted cables are quite prone to breaking down in half over long term. Always ensure that you use the right diameter of cables for the whole weight of the garage door that you plan out to install. The residential doors work great with 1/8 inch diameter cable, but the heavier doors more than 500 lbs may need 3/16″ or 5/32″ cable. Inspect the cables yearly, replacing any which look rusted or frayed. Make sure that the cables don’t rub against other items during operation and ensure that they are always sized correctly.
