- The call
- There was a sharp crack from the garage, and when you went to look the door had dropped on one side and jammed. A length of cable lies coiled on the floor by the bottom roller.

Garage door cables carry the weight of the door as tension held by the springs, which is why the work follows a careful, well-rehearsed sequence rather than simply hooking a cable back on. On a torsion system the technician clamps the door, disconnects the opener and unloads the springs with winding bars before any cable, drum or bracket is touched; on an extension system the door is instead raised fully and clamped so its pulley-mounted springs relax. Once the system is unloaded, replacing the cables is straightforward: the correct length is set, and the counterbalance is tensioned and locked off by the method that system calls for.

Scene 1
Cables only carry what the springs give them, so the springs are checked next. On a torsion system the technician looks for a gap in the coil that means a break, measures the wire and length to confirm the spring suits the door weight, and notes whether both springs on a double door match. On an extension door each spring is checked for stretch, a broken end or a missing containment cable through the middle. A weak or mismatched spring leaves one cable slack and the door heavy on one side, and if that is the story behind the cable, the spring work is explained and quoted alongside rather than left to surface later.
Scene 2
With the door clamped and the opener disconnected, the technician unloads the torsion springs. Two solid winding bars sized to the cone holes are used in turn: one holds the cone while the set screws are loosened, then the spring is let down a quarter turn at a time, bar over bar, until the coil is relaxed and the shaft turns freely. Every turn released is counted, because the same number goes back on later. On an extension door the technician instead raises the door fully and clamps it, which lets the springs hang slack. Once the tension is off, cables, drums and brackets can be handled like any other hardware.
Scene 3
The first thing you notice is a door that rises squarely, with both bottom corners leaving the floor together and the top section staying flat as it turns into the horizontal track. The bottom seal meets the slab along its whole length, so the draft and the strip of daylight at one corner are gone. The opener sounds calmer, because it is moving a balanced door rather than dragging a crooked one, and it stops reversing for no apparent reason. If you lift the door by hand with the opener released, it moves with light effort and holds where you leave it. That is what a correctly cabled door feels like.

Leave it. With one cable slack the door is being carried on one side only, so it is unbalanced and may bind or drop unevenly when moved. The technician arrives with clamps and a method for taking the door's weight before anything is moved, and that is the moment to lift it. Until then a stationary door is exactly what you want.
Yes, as a rule. The two cables were fitted together, have flexed around their drums the same number of times and have sat in the same slush, so the survivor is close to the end of its life. A new cable beside a stretched one also makes it harder to set the door level. Two matched cables give an even lift and one visit instead of two.
Yes, and both cause trouble. A cable that is too long runs out of drum groove and starts a second layer over the first, which wears it and throws the balance off near the top of travel. A cable that is too short leaves the door hanging out of level or the drum without a secure wrap. The correct length comes from the door height, the drum and the lift type, so the technician measures rather than guesses.
