Insignia ice maker shows E8 and stops; often occurs when the ice bin is full or sensor is blocked.

Safety first: Unplug the unit before cleaning sensors or adjusting switches.

• Empty the ice bin: Remove all ice from the storage bin and check for clumps that may be blocking the sensor or switch.
• Identify the full sensor: Many Insignia ice makers use either an infrared sensor pair (emitter and receiver) or a small mechanical lever/switch above the bin.
• Clean the sensor lenses: For IR sensors, wipe both sides with a soft, dry cloth. Do not use abrasive cleaners that can scratch the lenses.
• Check mechanical lever: If there is a lever-style full arm, move it up and down to ensure it is not stuck. It should move freely and return by spring tension.
• Inspect wiring: Access the side or top panel to trace the sensor wires back to the control board. Confirm connectors are fully seated.
• Reset and test: Plug in and run a cycle with the bin empty. If E8 appears immediately, the sensor assembly is likely defective and should be replaced.
