Ice maker runs continuously and does not shut off even when bin is full.

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

Steps:

• Check bin sensor: Inspect the bin thermistor or optical sensors for ice buildup, dirt, or misalignment. Clean and realign as needed.
• Test sensor (advanced): Measure resistance of the bin thermistor or follow Café service diagnostics for optical sensors.
• Replace sensor assembly: Install a new Café bin thermistor or optical sensor kit if the existing one is unresponsive.
• Evaluate control board: If sensors test good but the unit still overproduces, the main control board may be misinterpreting signals and should be replaced.
