How to adjust dominator garage door.
If your door doesn t rise at least five feet when it is suppose to be opening hold the bottom of the garage door while it is lowering.
Garage doors are very easy to adjust and can be done in less than 15 minutes.
Each garage door opener has limits which control the opening and closing heights of the door.
These limits must be set correctly for the door height to have a proper seal as well as to allow for adequate clearance.
To make fine adjustments try adjusting the lifting cable instead of the spring.
The cable is attached to the door and runs to an s hook that attaches to the track support.
Adjust the length of the cord so that its toggle is no more than 1 8m from the ground.
If installing on a door with a bad wave action lengthening the arm will assist in reducing this effect.
This will adjust the open force.
Continue to adjust the limit switch and testing until you obtain the desired results.
This video details how to adjust the opener force and travel of the door.
