Unit powers on but stops mid-cycle and shows E2 on the display.

Safety First: Disconnect power before working inside the ice maker.

Steps to resolve E2:

• Empty the bin: Remove all ice from the storage bin and check if the error clears after a restart. Sometimes a jammed ice pile can block the sensor.
• Clean the sensor: Locate the ice level sensor (often an infrared emitter/receiver pair near the top of the bin). Clean the sensor windows with a soft cloth and mild soapy water, then dry thoroughly.
• Check alignment: Ensure the emitter and receiver are aligned and not bent out of position.
• Inspect wiring: With power unplugged, inspect the sensor harness for loose plugs or damaged wires. Reseat connectors at both the sensor and control board.
• Test operation: Restore power and run a cycle. If E2 returns immediately, the sensor may be defective.
• Replace sensor: Remove mounting screws or clips, disconnect the old ice level sensor, install the new Koldfront-compatible sensor assembly, and reconnect wiring.

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