Fix a Cabinet Door That Won't Close

Cabinet doors develop personalities over time. One day the door closes flush, the next it sits proud of the frame by a quarter inch, refusing to latch. The culprit is usually simple: wood movement from humidity changes, screws that have worked loose in particleboard, or hinges that have shifted just enough to throw the door out of alignment. A door that won't close looks sloppy and lets cooking smells escape, but the fix is straightforward. Most cases take fifteen minutes and require nothing more than a screwdriver and patience. The solution depends on what the door is doing. Some doors spring open because the catch no longer meets the strike. Others close but won't stay closed because the latch hardware has shifted. A few doors have swollen from moisture and bind against the frame. Diagnosing which problem you have takes thirty seconds of observation. After that, the repair is mechanical and predictable.

1. Spot loose hinges fast. Open the problem door fully and inspect each hinge. Use a screwdriver to test every screw — both on the door side and the cabinet frame side. Tighten any that turn easily. Particleboard cabinets often lose screw grip over time, especially on doors that get pulled open frequently.
2. Restore grip to stripped holes. For screws that won't tighten, remove the screw completely and fill the hole with wooden matchsticks or toothpicks dipped in wood glue. Break them off flush and let dry for ten minutes, then drive the screw back in. The wood gives the threads something to bite. For severe stripping, drill out the hole and glue in a short length of dowel, then re-drill a pilot hole.
3. Fine-tune hinge position. Modern European hinges have adjustment screws that shift the door in three directions. Loosen the mounting screw slightly, adjust the door position using the small adjustment screws, then retighten. For traditional butt hinges, you may need to remove the hinge and shim it out with cardboard to bring the door forward or backward.
4. Find swollen wood spots. Close the door slowly and watch where it makes contact. If the door edge binds against the frame before the latch catches, the wood has swollen. Mark the binding spot with a pencil. This happens most often on the latch side during humid months.
5. Shave down binding edges. Remove the door and secure it in a vise or clamp it to a workbench. Use a block plane or coarse sandpaper on a block to remove material from the marked area. Work gradually — take off a sixteenth of an inch, rehang the door, and test. Repeat until the door closes without resistance. Seal the raw edge with paint or polyurethane to prevent future swelling.
6. Secure the catch mechanism. If the door closes but won't stay closed, the magnetic catch or roller catch has shifted. Loosen the catch mounting screws and reposition it so the door pulls tight when closed. Test the hold strength — the door should require a deliberate pull to open. Replace worn catches if adjustment doesn't restore the hold.
7. Test full closure and alignment. Open and close the door twenty times through its full range of motion. Listen for squeaks, check that it closes flush with adjacent doors, and verify the gap is consistent top to bottom. Make final micro-adjustments to the hinges until the door operates smoothly and sits perfectly in the closed position.
