E6 appears on the display and the ice maker stops mid-cycle; ice may be partially formed.

Safety: Unplug the unit before working inside the ice bin area.

Steps:

• Check for blockage: Open the ice storage bin and remove excess ice. Ensure no cubes are stuck in front of the ice full sensor window or hanging from the evaporator into the sensor path.
• Clean sensor lenses: If your SMAD model uses an infrared ice level sensor, gently clean the emitter and receiver windows with a soft cloth and warm water. Do not use abrasive cleaners.
• Inspect alignment: Verify that the sensor brackets are not bent and that the emitter and receiver face each other directly.
• Check wiring: Follow the sensor wires to the control board. Reseat the connectors and look for damage.
• Test operation: With the unit reassembled and powered, simulate a full bin by placing an object in front of the sensor (if accessible) and see if the unit responds. If E6 persists, the sensor assembly is likely defective.
• Replace sensor: Remove mounting screws and install a new ice full sensor / infrared level sensor assembly. Reconnect wiring and test.
