Wine cooler displays dE or a door icon and beeps; interior light may stay on and cooling may stop after a while.

Safety: This fault is generally low risk, but always unplug the unit before removing trim or panels.

• Check door closure: Ensure no shelves, bottles, or racks are preventing the door from closing fully. Verify that the door closes flush with the cabinet and that hinges are not sagging.
• Inspect gasket: Examine the door gasket for tears, warping, or debris. Clean the gasket and cabinet mating surface with mild soap and water. Replace the gasket if it is deformed and not sealing.
• Locate door switch: On many Monogram wine coolers, the door switch is a magnetic reed switch embedded in the cabinet frame, triggered by a magnet in the door. Others use a plunger-style switch.
• Test switch function: With the door open, press the plunger or place a magnet near the reed switch location and see if the interior light turns off and the door alarm stops. If not, the switch may be faulty.
• Electrical test: Unplug the unit, access the switch wiring (often behind the front trim), and test continuity across the switch while actuating it. Replace the door switch if it does not change state.
• Check wiring: Inspect the harness from the switch to the control board for damage or loose connectors. Repair or replace as needed.

After repair, confirm that the dE indication clears when the door is properly closed.
