Ice maker runs continuously without cycling off, even when the basket is full of ice.

Safety first: Unplug the unit before inspecting sensors.

• Test sensor response: With the unit running and basket in place, manually block the ice full sensor (or lift the mechanical arm) to simulate a full basket. The unit should stop making ice after a short delay.
• Clean sensor: Wipe the infrared sensor lenses or mechanical arm pivot to ensure free movement and clear detection.
• Inspect wiring: Confirm the sensor harness is connected securely to the control board.

If the unit continues to run regardless of sensor state, the sensor or control PCB is likely faulty and should be replaced to prevent overfilling and potential overflow.
