If the motor is jumping in the closed position then something is likely causing a safety stop. The two reasons most commonly are that something is blocking the sensor or the torque is too high. As the door will open Torque is not the probable cause. It is likely something in the protective door block circuit preventing it from going closed. If you press and hold the close button will the door close momentarily? If so then there is definitely something telling it that it is not safe for it to close. If neither of those Solutions work then you probably have a circuit failure which was the cause of the fuse failure in which case the solution is to replace the genie.
