E12 code; unit may not recognize door or bin position and may not start ice production.

Safety first: Unplug the ice maker before accessing switches or wiring.

• Step 1 – Check door closure: Ensure the door closes fully and the gasket is not preventing contact. A partially open door can keep the switch from activating.
• Step 2 – Locate door/bin switch: Identify the small switch or sensor near the door frame or bin area. Some GE Profile models use a magnetic reed switch with a magnet in the door.
• Step 3 – Test switch operation: With a multimeter, check continuity across the switch terminals while opening and closing the door or moving the bin. The reading should change from open to closed.
• Step 4 – Adjust magnet alignment: If using a magnetic switch, ensure the magnet in the door aligns directly with the switch when closed. Adjust the door or switch position if needed.
• Step 5 – Replace faulty switch: If the switch does not change state or is physically damaged, replace it with the correct GE part.
• Step 6 – Inspect wiring: Verify the harness from the switch to the control board is intact and properly connected.
