Display shows dO and an alarm sounds, indicating a door open condition even when doors appear closed.

Safety First: No internal electrical work is required for initial checks.

Steps:

• Check door alignment: Ensure the refrigerator and freezer doors are level and close fully without interference from shelves or food items.
• Inspect gaskets: Examine door gaskets for tears, warping, or debris. Clean with warm soapy water and dry thoroughly.
• Test door switch: Open the door and manually press the door switch. The interior light should turn off and the alarm should stop. If not, the switch or sensor may be faulty.
• Check door magnet (for reed sensors): Verify that the magnet embedded in the door edge is present and not loose.
• Replace faulty parts: Install a new Midea door switch or gasket as needed. Adjust door hinges if misaligned.
