Abstract
A method and apparatus for controlling the operation of a garage door opener is disclosed wherein a micro-controller de-energizes a garage door drive motor for a first period when a stop command is received while the garage door drive motor is energized and the garage door is travelling in a first direction. The micro-controller then energizes the drive motor to move the garage door in the opposite direction from the first direction for a second period. The micro-controller then de-energizes the drive motor, placing the door in a static state.
