L1 or LO code displayed; the unit indicates a low ice level even when the bin is partially full, and it continues to run excessively.

Safety First: Disconnect power before cleaning or adjusting sensors.

• Clean sensor lenses: Locate the bin level sensor near the bin opening. Clean both emitter and receiver lenses with a soft cloth and mild soap solution.
• Check alignment: Ensure both sides of the sensor are directly facing each other and firmly mounted.
• Remove obstructions: Make sure no reflective or opaque objects (scoops, liners) are blocking or confusing the sensor beam.
• Inspect wiring: Verify that the sensor harness is intact and properly connected to the control board.
• Replace the sensor: If cleaning and alignment do not correct the issue, replace the bin level sensor assembly with the correct Amana part.
