Display shows E2 and the ice maker stops mid-cycle; ice may partially form but harvest does not complete.

Safety first: Disconnect power before reaching inside the ice bin or removing covers.

Steps to address E2:

• Check for actual full bin: Empty the ice basket completely and restart the unit. If E2 remains, continue.
• Locate the ice level sensor: On many NewAir countertop ice makers, the sensor is an infrared pair (emitter and receiver) near the ice chute or bin opening. On some undercounter models, it may be a mechanical lever switch.
• Clean the sensor: Wipe the sensor windows or lever area with a soft cloth dampened with warm water. Mineral deposits or frost can block the beam or jam the lever.
• Inspect alignment: Ensure the emitter and receiver face each other directly and that mounting brackets are not bent. Adjust gently if misaligned.
• Check wiring: With power unplugged, verify the sensor harness is firmly connected to the main PCB and that no wires are pinched or broken.
• Replace if defective: If cleaning and reseating do not clear E2, replace the ice level sensor assembly with a NewAir-compatible part.

Note: If a new sensor does not resolve E2, the control board may not be reading the sensor correctly and may require replacement.
