Usually there is a hand-switch where the arm from the door connects to the Drivescrew. It will often have a cord hanging down that you can pull to disengage the arm from the screw. It's there so that you can manually move your door if the power goes out. If the drivescrew spins and nothing moves, then you probably need to get on a stepstool and click the lever back up to re-engage with the screw. Good Luck!
