E19 error appears; unit may not detect when the bin is empty and fails to restart ice production.

Safety: Unplug the ice maker before inspecting the bin area.

• Check bin for obstructions: Remove the ice basket and ensure no ice chunks or foreign objects are blocking the bin level arm or sensor.
• Inspect mechanical arm (if equipped): Move the arm up and down; it should move freely and click the internal switch. If stiff, clean and lubricate lightly with food-safe lubricant.
• IR sensor type: Clean the emitter and receiver lenses with a soft cloth and ensure they are aligned.
• Test switch/sensor: Use a multimeter to test continuity of the bin level switch or follow service data for IR sensor testing. Replace the bin level sensor assembly if faulty.
• Check wiring: Verify the harness from the bin sensor to the control PCB is intact and connectors are secure.
