Ice cubes are oversized, clumped together, or difficult to break apart.

Safety first: Unplug the ice maker before adjusting sensors.

Steps to correct:

• Adjust thickness setting: Reduce the ice thickness setting via the control panel or mechanical adjustment screw, following the user manual.
• Clean thickness sensor: Remove mineral deposits from the probe or sensor to ensure accurate detection.
• Observe harvest timing: Watch a full cycle to see if harvest begins promptly once ice reaches the sensor. If harvest is delayed, the sensor may be faulty and should be replaced.
• Check for firmware reset: Perform a power reset to clear any control glitches.

When to call a technician: If adjustments and sensor replacement do not resolve the issue, the control board may need professional evaluation.
