How is garage door tension adjusted?

Adjusting the tension of a garage door is primarily done by manipulating the torsion springs located above the door. These springs are responsible for counterbalancing the weight of the door and enabling smooth operation. When the door is properly balanced, it can easily open and close. Adjusting these springs involves either tightening or loosening them to achieve the desired tension, which directly impacts how easily the door operates.

The other methods mentioned, such as changing the door's frame or modifying the track angle, do not address the core issue of tension adjustment. While frame changes may affect the overall integrity and fitting of the door, they do not deal with the balance provided by the springs. Replacing the door entirely would be an inefficient and unnecessary approach when the issue is specifically related to the tension applied by the torsion springs.
