Garage Door Close-Force Screw Needs Adjustment
When a garage door reverses before it even touches the floor, the issue may be with the garage door adjustment screw.
Garage door openers have an adjustment screw that controls the closing force—the pressure with which a door is allowed to descend before the motor switches off.

The friction of the door rollers within the tracks is fooling the door opener into thinking the door has reached the floor, and the opener needs to be adjusted for less sensitivity.
