The door went up as usual this morning, then stopped a third of the way with one corner higher than the other. It is wedged at an angle in the opening, the opener is humming, and nothing you press will move it.
A failed cable is usually telling you something about the rest of the system. It may have frayed against a bent track, rusted at a corroded bracket, jumped its drum when the door closed on an object, or slackened because a spring is weak. Cable replacement therefore starts with the whole lifting path: both cables, both drums or pulleys, the bottom brackets, rollers, hinges, track and springs. Whatever caused the failure is put right alongside the new cables, so the fresh steel is not rubbing on the same rough edge that finished the last set. That is what turns a repair into a lasting one.

Scene 1
Both cables are examined even when only one has failed, because they are the same age and have made the same trips. The technician looks along each for broken wires, thinning near the bottom loop, rust bloom, kinks, and flattened spots where the cable has rubbed. The ends get particular attention: the swaged stop that seats in the drum and the loop or ferrule that rides on the bottom bracket pin. The two are compared for length as well, since a stretched or slipped cable shows as one corner of the door sitting higher. This comparison decides what is fitted and explains any crookedness you have noticed.
Scene 2
Where the inspection found a drum with worn grooves or a slipped set screw, or a bottom bracket bent by a bumper or eaten by salt, that hardware is replaced while the system is unloaded and the cables are already off. Drums are changed as a matched pair so both sides wind identically. A new bottom bracket is fixed with the correct fasteners into a sound part of the section, and the bottom roller is renewed if its stem or wheel is worn. Doing this in one visit adds a few minutes and avoids fitting fresh cable onto the very part that damaged the old one.
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.
What shapes the quoteMount Joy Door & Opener Co.
FeesSame any hour
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.
Leave the door in the position it is in and stop using the opener. Move the car and anything else you need out of the garage by another door if you can, and clear the floor near the door so the technician has room to work. If a cable jumped because the door closed on something, leave the object where it was; it helps explain what happened.
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.
