RE: sears garage door opener stuck

It sounds like your door is opening too far and the trolley is jamming against the bolt just in front of the motor unit. If so, do this:

Close the door and then locate the 'up limit' control on the side of the motor unit. Turn this 2 full turns in the opposite direction of the arrow printed on the cover. Should do it.
