What to do
- Check the closer arm adjustment (usually a dial or screw) and adjust the tension so the door closes fully but not too hard.
- Check the latch and strike plate alignment, adjusting or repositioning the strike plate if needed.
- Tighten all hinge screws.
- Sight along the door frame for any visible bends, especially near the closer arm mounting point.
- For a bent frame, gently bend it back if the damage is minor, or plan for a replacement if it's severe.
- Test the door through several full cycles after each adjustment.
