a.. 3 Adjust the travel dial using your flathead screwdriver. The back of the garage door control unit should have two dials that are inset in to the units case. The dial on the right hand side will reduce or lengthen the amount of travel the door has, based on which way you turn it. If the door isn't closing all the way, adjust to the left. Adjust a one-half turn and open and close the door. Adjust either way as necessary.
a.. 4 Adjust the torsion dial with the screwdriver. The torsion dial is on the left hand side on the back of the control panel and regulates how much pressure the door has when opening and closing. If you can't get the door to go up when it's down, you may have to raise the torsion by turning the dial to the right. If the door closes and then starts back up, you might have too much torsion.
