IceKing ice maker overfills the bin and does not stop making ice.

Safety first: Unplug the unit before working near sensors or wiring.

Step-by-step checks:

• 1. Clean sensors: Wipe the bin full sensor lenses or mechanical switch area with a soft cloth.
• 2. Check alignment: Ensure optical sensors face each other correctly and are not blocked by bin walls or ice.
• 3. Test switch: For mechanical switches, press the actuator and listen for a click. Replace if it does not operate smoothly.
• 4. Replace sensor: If the bin continues to overfill, replace the ice bin full sensor or level switch.

When to call a technician: If a new sensor does not resolve the issue, the main control PCB may not be interpreting the signal correctly.
