- The call
- Someone left the snow shovel leaning in the opening and the door came down on it. Now a loop of steel cable hangs loose beside the track and the door refuses to close the last few inches.

Standing inside with the door closed, you notice the cable on the right side near the floor has gone fuzzy. A handful of broken wires stick out like a bottle brush and the steel underneath is brown.
A cable visit runs in a set order. First the opener is disconnected and the door clamped so nothing can move. Then the counterbalance is unloaded so the drums, cables and bottom brackets can be handled calmly. The old cables come off, the drums and brackets are inspected, and new cables of the correct specification go on. Both sides are tensioned evenly until the door sits level, then the springs are wound back to the turns the door height calls for. Finally the door is balanced by hand, the opener reconnected and its travel and reversing checked. You are shown the finished door working before the technician leaves.

Scene 1
The last part of the first look follows the door's path. The technician checks that the vertical tracks are plumb and evenly spaced from the door, that the curve into the horizontal run is smooth, and that the track brackets are tight to the jamb. Rollers are checked for cracked wheels and bent stems, hinges for splits, and the bottom section for a dent or bow from a vehicle. Any of these can rub a cable or hold one corner back, and each is easier to correct while the counterbalance is unloaded. If the door is off its track as well, that is set straight as part of the same work.
Scene 2
The replacement cables are chosen for construction, diameter and length rather than taken from a general bin. Residential doors use galvanized aircraft-type wire rope, and the length depends on the door height, the drum profile and the lift type; a high-lift door or a double door has its own requirements. The swaged stop on the new cable is seated in the drum slot and the cable is wrapped in the groove in the correct direction, leaving the drum on the side that leads straight down to the bracket. At the bottom, the loop goes over the bracket pin and is secured. The other side is fitted the same way.
Scene 3
You can confirm the door is still balanced any time without touching a spring or cable. With the door closed, pull the opener's release cord so the trolley disconnects, then lift the door by its handle or a safe gripping point to about waist height and let go gently. A balanced door should not lift or fall far on its own; a little slow drift is normal, and what calls for a technician is rapid movement, a heavy feel, binding in the track, or a result outside the manufacturer's balance instructions, not drift alone. Reconnect the opener as the manual describes, usually by running it once. Doing this each season catches wear early and keeps the opener working lightly.

The opener is disconnected and the door clamped. The technician identifies the counterbalance type, inspects both cables, the drums, brackets, rollers, track and springs, and explains what is found. The springs are unloaded, the old cables removed, new ones fitted and set so the door is level, and the springs wound back. The door is then balanced by hand, the opener reconnected and its safety features tested while you watch.
Whether the door is sitting crooked, jammed partway or on the floor; whether you can see a cable hanging loose, frayed or wrapped around the shaft; whether there is a spring above the door or springs along the tracks; the door's rough height and whether it is a single or double; and what happened just before, such as the door coming down on something. A photo of the drum end and the bottom corner is useful.
The bottom bracket is where the cable attaches, so whenever the springs are wound it carries a share of the door's weight as tension. Loosening it while the counterbalance is loaded releases that tension all at once. Many manufacturers now fit tamper-resistant fasteners for this reason. The technician unloads the springs first, after which the bracket is just a piece of hardware to unbolt and replace.
