My garage door is forced all the way in the closed position, the cable is jammed so far forward its almost into the pully. This is a older model sears opener. When I plug in the opener its still trying to move the door into the down position making it impossible to free the cable so I can re-attach the safery pull and get it working again. If I can free the cable I can fix the door. Is there a switch that I can hit to make the motor manually reverse itself to the fully open position. Im stuck as to what to do here.
