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:
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 limited warranty from the hardware manufacturer.
