How to close a garage door with a broken cable?

To close a garage door with a broken cable, which leaves door crooked, unstable, and potentially off track, you must do so manually with help and secure it, avoiding use of automatic opener. First, disconnect opener by pulling emergency release cord to prevent opener from pulling uneven door and causing more damage. If door is open and cable snapped, door may be hanging unevenly with one side lower, so you need at least two people, one on each side, to slowly lower door, keeping it as level as possible to prevent it going further off track or bending panels. Lower door slowly, controlling descent, as door will be heavy, 150 to 300 pounds, and side with broken cable will tend to drop faster. Once door reaches floor, engage manual slide lock on track to secure it, as door may not stay closed due to lack of cable tension. If door is stuck open and cannot be lowered due to being off track, do not force it, as forcing can damage tracks and rollers; instead, call professional for emergency service. If cable is tangled in rollers, carefully untangle only if door is clamped and springs de-tensioned, but professional handling is safer. After closing, do not operate door again until cables replaced, as operating with broken cable can cause door to fall and cause injury. Professional cable replacement costs 100 to 250 dollars, or 250 to 600 dollars if springs also need replacement, and includes rebalancing.
