Warm air or condensation around the door frame; door feels loose.

Safety: This is a mechanical repair; unplug if you will remove the door.

• Inspect gasket: Check for cracks, tears, or flattened areas on the door gasket. Close the door on a sheet of paper; if it pulls out easily, the seal is weak.
• Adjust hinges: Loosen hinge screws slightly and adjust the door so it is square with the cabinet, then retighten.
• Replace gasket: If damaged, pull out the old gasket from the door channel and press in a new Della Marta-compatible gasket, working around the perimeter.
• Check for obstructions: Ensure shelves or bottles are not preventing the door from closing fully.
