E10 displayed; unit may not detect ice production correctly, stopping too early or running continuously.

Safety first: Turn off and unplug the ice maker before working near the evaporator or ice chute.

• Step 1 – Identify sensor type: On GE Profile clear ice makers, an ice thickness probe often contacts the ice slab. On nugget models, an optical sensor may monitor ice level in the chute.
• Step 2 – Clean sensor surfaces: Remove mineral deposits from the thickness probe or optical lenses using a soft cloth and white vinegar. Rinse and dry thoroughly.
• Step 3 – Check alignment: Ensure the thickness probe is positioned per the service manual, typically just touching or slightly above the evaporator plate. Adjust gently if bent.
• Step 4 – Inspect wiring: Follow the sensor wires back to the control board. Reseat connectors and look for damaged insulation.
• Step 5 – Replace sensor: If cleaning and alignment do not resolve E10, replace the ice thickness or harvest sensor assembly with the correct GE part.
• Step 6 – Reset and calibrate: Some models require a calibration or test cycle after sensor replacement. Follow the service manual procedure to ensure accurate ice thickness detection.
