Adjust the up and down controls on the opener housing with your screwdriver. You'll see the adjustable knob on the back of the garage door opener. Turn it a quarter of a turn either clockwise or counterclockwise to adjust for door height. If the door doesn't go all the way down, you need to turn the up/down knob counterclockwise. If it doesn't go all the way up, you need to turn it clockwise。
