Jammed pocket door!!!!!
 

How to fix a Jammed pocket door? seems like one of the "wheel" get loose and now the door stuck closed unless I lift up the door a little bit to open it. seems there are no access to the rail/wheel area without taking apart the drywall or the door flame?

There is a vertical trim that is installed on the left and right of the door that will prevent the door from swinging out (depends on what way the top rail is facing). Some door jams you can remove the trim as is, some you will need to remove the casing first (the trim that hides the gap between the drywall and door frame).
