ABSTRACT:
A method is provided for use with a movable barrier operator that has no user-initiable dedicated learning mode of operation. At least one parameter is monitored that corresponds to force as applied to a movable barrier to selectively cause the movable barrier to move between at least a first position and a second position. An excess force threshold value is automatically changed in response to the monitored at least one parameter to provide an updated excess force threshold value. Both the updated excess force threshold value and the monitored at least one parameter are used to determine when excess force is being applied to the movable barrier via the movable barrier operator. A predetermined action is taken when excess force is being applied to the movable barrier via the movable barrier operator.
