Some of the common problems which we encounter in replacement kitchen doors include bent cabinet door, which is basically due to low quality wood or exposing it in breezy environments. The doors are attached to the cabinet via an interfacing device called hinges, which basically move in three directions, up and down, side to side and in and out. In this case, we will consider in and out imbalance, which means the door touches the bottom but leaves a space a the top. Now adjust the bottom hinge by popping the screw out because when the door moves inside it will automatically fit in accordance to the another door. Carry on the same procedure for all the hinges to set up and repair the crooked door. The basic idea behind this method is loosening the screws so that the door will allocate itself with the cabinet. And now your cabinet door is easily fixed by simple hinge adjustment.
