In case a garage door cable snapped, the door will hand on one side and will not operate properly. Most probably, the user will not be able to open it fully or at all. The most common cause of cable snapping is fraying due to extensive wear and tear. A cut in the cable may also cause its breaking. Even a small cut, which is hard to notice without close inspection, can lead to the snapping. This is because the garage door cables connect the door to the spring or springs and are constantly under great tension.
The problem can be resolved only with the replacement of the snapped cable. This has to be done timely so that the safety and security risks associated with the issue are eliminated. The old cable must be replaced with a new one of exactly the same length and diameter. Professional replacement is required for safety reasons.
