Stuff happens. This you can count on.
When minor problems arise with your cabinetry, consider the following ideas before calling your dealer/installer for help:
Your hardware can become loose from frequent use. Simply use the appropriate screwdriver based on the screw head type to re-tighten any loose decorative hardware by turning the screw clockwise.
Minor door misalignment can be corrected by adjusting the hinges. Generally, with the cabinet door open, the side-to-side adjustment slot is on the door part of the hinge and the up and down adjustment is on the frame portion of the hinge.
For hinges and hardware that do not work properly, contact your dealer for assistance. In most cases, cabinetry hardware is protected by a lifetime guarantee from the hardware manufacturer.
