Display shows dE or a door icon; interior light may stay on and cooling may stop intermittently.

Safety: Most checks can be done with power on, but unplug the unit before removing panels or working on wiring.

Steps:

• 1. Check for obstructions: Ensure shelves or bottles are not preventing the door from closing fully. Verify the gasket is seated correctly all around.
• 2. Inspect door switch: Locate the door switch (mechanical plunger or magnetic reed) usually at the top or side of the opening. Press it manually; the interior light should turn on/off accordingly.
• 3. Test continuity: With power off, remove the switch and test it with a multimeter. It should open and close electrically when pressed/released. Replace if it does not change state.
• 4. Check magnet (if reed switch): On some La Sommeliere models, a magnet in the door frame activates a reed switch in the cabinet. Ensure the magnet is present and aligned; replace the door trim or magnet if missing.
• 5. Replace faulty switch: Install a new La Sommeliere door switch assembly if the original is defective. Reconnect wiring securely.
• 6. Test operation: Restore power and confirm that the dE indication clears when the door is closed and that the light and cooling behave normally.
