- The door opens very fast but is difficult to lower. The spring(s) are wound too tight. Adjust the tension. Review Steps 5 or 5.1, depending on the spring type.
- The door closes quickly but is heavy to raise. The spring(s) are not wound tight enough. Adjust the tension. Review Steps 5 or 5.1, depending on the spring type.
- The door works well, but goes back up when it’s 2 to 3 inches from the threshold of the door. The spring(s) are a little too tight Adjust the tension. Review Steps 5 or 5.1, depending on the spring type.
- The door doesn’t close squarely on the floor. The floor isn’t level compared to the vertical tracks. If it is a problem with the floor, the threshold must be corrected to be level.
- The door is difficult to open at the beginning of its cycle. The exterior frame weatherstripping is too tight. Loosen it and move it a bit away from the door (the base of the weatherstripping should be about ½" from the door).
- The door is difficult to open at the end of its cycle. The horizontal tracks are not perpendicular to the axis of the door. To check, use a tape measure and Figure 17 in the manual.
- The top section doesn’t close completely. Adjust the position of the upper support (see Figure 16 in the manual).
