    The garage door should have one or two torsion springs, with each spring consisting of spring coils, a winding cone, and a stationary cone. Luckily, the spring coils are all color-coded based on spring size, while the winding cone is also color-coded separately, black or red. The winding cone color helps you establish on which side of the garage door the spring is used.

    But just to make sure you are on the right side, red winding cone torsion springs should be used on the left side of the garage door, while black winding cone torsion springs should be used on the right side of the garage door from inside facing out.

    Note that failure to correctly install the torsion springs will cause the door to malfunction and could cause severe injury.

    Also, if your garage has low headroom, consider consulting supplemental low headroom instructions since these instructions will not be of great use to you.

    Slide the torsion springs onto the designated spring tube, with the red winding cone going to the left end and the back winding cone going to the right end.

    Next, install cable drums, which are also color-coded. The black drum goes on the right while the red drum goes on the left. The set bolts on the drums should face the springs. Can a garage door work with one spring? Well, it depends.
