Display shows E9; door alarm may sound continuously; unit may think the door is open even when closed.

Safety: Unplug the wine cooler before removing any trim or panels around the door frame.

Steps to address E9:

• Check door closure: Ensure the door closes fully and the gasket is not obstructed by shelves, bottles, or warped trim.
• Locate the door sensor: Many Kenmore wine coolers use a magnetic reed switch embedded in the cabinet frame and a small magnet in the door. The switch may be behind a small plastic cover near the top or side of the opening.
• Inspect the magnet: Verify that the magnet is still present in the door edge and has not fallen out or shifted. Re-secure or replace if missing.
• Test the reed switch: With the unit unplugged, access the switch and disconnect its wires. Use a multimeter to check continuity while placing a magnet near the switch. The reading should change (open/close) as the magnet moves.
• Check wiring: Inspect the harness from the switch to the control board for pinched or broken wires, especially where it passes through the cabinet.
• Replace faulty parts: Replace the door switch (magnetic reed switch) or door magnet if they do not operate correctly. Secure them in the original positions so alignment is correct when the door is closed.
• Test operation: Restore power and close the door. Confirm that the interior light and door alarm behave normally and that E9 clears.
