Display shows dE and the dispenser or door functions may be limited.

Safety first: Unplug the refrigerator before removing any control panels or door switch assemblies.

dE indicates the control is detecting an abnormal door status.

• Check door closure: Make sure all doors are closing fully and the gaskets are not obstructed by food packages or shelves.
• Inspect door switch: Locate the door switch (usually in the upper frame area). Press it manually and listen for a click. If the interior lights do not respond or the click is absent, the switch may be faulty.
• Test with a multimeter: With power disconnected, remove the switch and test for continuity when pressed. Replace if it does not change state.
• Check wiring: Inspect the harness leading from the door switch to the top hinge area for pinched or broken wires.
• Control reset: After repairs, restore power and hold the lock or settings button (per your model's instructions) to clear the error if needed.
• Call a technician: If the switch and wiring are good, the dispenser or main control board may be misreading the door status and should be professionally diagnosed.
