When the door does not function properly as normal, garage door cable replacement is necessary. Single lifting cables are present on each door side and breaks lead to uneven raising and lowering of the door and this completely. The different lifting cables related to the garage door are the following.Extension Cable here the storage of energy is through extension and this is perpendicular to the door extending inside the space running parallel to tracks. There is energy release during the lift operation, and it recharges upon lowering the door.Torsion spring here coiling leads to energy storage and this is near the wall and on the upper door part running parallel to this. The spring expands to release energy when lifting the door and coils back upon lowering.
