Replace old screws with new ones that are a bit longer to ensure the cabinet door is held firmly in place.
Replace the hinges with new hinges (use longer screws) to solve problems with the hinges.
If your cabinet door is off balance, unscrew the hinges and drill a clean hole where the existing holes are-put in a wooden dowel with wood glue, let dry then reinstall the cabinet.
You can add a latch system or self-closing hinges on your cabinet doors that won't stay closed.
