Display shows E16; ice maker stops; unit may beep continuously; internal light may flash.

Safety: Unplug the unit before working around the door switch area.

Steps to resolve E16:

• Check door closure: Ensure the door or access panel closes fully and that nothing (like ice or packaging) is obstructing it.
• Inspect switch actuator: Locate the door switch (often near the top or side of the opening). Confirm that the door or panel properly presses the switch plunger when closed.
• Test switch: Remove the switch from its mounting and test continuity with a multimeter while pressing and releasing the actuator. Replace the door switch if readings are not consistent.
• Check wiring: Inspect the switch wires and connector for damage or looseness. Reseat the connector at the main PCB if accessible.
• Reassemble and test: Refit the switch, close the door, restore power, and verify that E16 clears and the interior light behaves normally.

Tip: If the door is misaligned, adjust hinges or leveling feet so the door seals evenly.
