Ice bin overfills and ice spills out even when bin is full.

Safety: Unplug the ice maker before adjusting the ice level mechanism.

Steps:

• Inspect bin arm: If your SMAD model uses a mechanical arm, verify it moves freely and is not obstructed by ice. Clear any jams and ensure the arm can rise when the bin is full.
• Test sensor: For infrared sensors, clean the lenses and check alignment. If the unit continues to make ice with the bin full, the ice level sensor may be stuck in the "empty" state.
• Check wiring: Confirm the sensor harness is connected securely to the control board.
• Replace sensor/arm: If the mechanism does not respond to bin level, replace the ice level switch or sensor assembly.
