When my craftsman garage door opens up it goes all the way up until the trolley hit the safety pin.
Garage door trolley hits bolt.
First visually verify that the trolley is against the stop bolt make sure the garage doorway is clear of persons or obstructions release the door from the garage door opener by pulling the emergency release handle manually bring the door to the closed position loosen the chain or belt by adjusting the outer nut 4 to 5 turns.
First you should check the safety sensors.
I have compared with the other garage door opener i have and it stops on the way up 1 2 inch before the trolley hits the safety screw bolt.
Then look to see if the rollers are in working order.
Do you know what i need to do to limit the movement of the door model 139 53650srt craftsman thanks.

This may move the chain trolley of the garage door opener.
