The most common cause for door malfunctioning is improper installation. The door frames must be plumb and square. Misalignment is easily detected by observing if the locks function freely without hanging up or causing friction binds.
Another point to look for is inconsistency of the closure gap. If the gap is wider at the top than the bottom, the unit is misaligned. However, if the door and locks function freely then no further adjustment is recommended. With the door closer disconnected and the door opened at a 45- degree angle, the leaf should remain in one place. If the door drifts open or closed, then the frame is not level (vertical alignment).
The best way to re-adjust the door frame for lock adjustment is to remove the door stops, thus exposing the mounting bolts. Loosen the bolts and physically move or change the shims to be located between the wall and the outside edge of the frame. Removing shims for one side or adding to the other side will bring the frame in closer or spread further apart. Retighten all bolts upon completion. Re-install the door stops. If the frame is not vertical, then it is recommended that the mounting bolts be removed one at a time and the hole elongated in the direction that the door must be moved. If the door leaf is dragging, then elongate the mounting holes vertically. Gently pry the door frame up until sufficient clearance is obtained. Retighten all bolts upon completion.
The hinges should be checked periodically to ensure that all the screws are tight. Loosening the hinge screws, repositioning the door, and retightening the screws may accomplish some minor adjustment. Another cause for door misalignment (assuming the installation was correct) is settlement of the building and/or the wall not being capable of sustaining the weight and constant movement of the door.
