How to adjust a garage door opener up and down?

By setting the garage door movement limits, you specify the point at which it will stop moving when opening or closing.

You might want to consider adjusting the limits if:

• Your garage door does not open or close all the way
• The door reverses when closing.

You will need a flathead screwdriver to change the limits.

Remember, if you set the limits incorrectly, the garage door will not function properly, which might be unsafe.

After each adjustment, test the garage door opener several times.

To adjust the garage door opener up and down, follow these steps:

Up Travel

Locate the UP limit adjustment screw on the garage door opener and turn it clockwise. One turn increases the up travel by 2 inches.

To decrease the up travel, rotate the screw counterclockwise.

Down Travel

To increase the down travel, find the DOWN limit adjustment screw and turn it counterclockwise. One turn equals 2 inches of garage door travel.

To decrease the down limit, rotate the screw clockwise.
