GE ice maker ice bin overfilling; ice spills out even though unit should stop when full.

Safety first: Turn off the ice maker before working in the bin area.

• Check shutoff arm: If your model has a mechanical arm, ensure it moves freely up and down. Clear any ice blocking its movement.
• Clean optical sensors: For optical systems, gently clean the emitter and receiver lenses with a soft cloth.
• Inspect switch: If the arm does not click a switch when raised, the switch may be broken and should be replaced.
• Replace sensor assembly: If the bin full system does not stop production after cleaning and inspection, replace the bin full sensor or arm assembly.
