E10 error; unit may beep and stop, often associated with abnormal internal temperature readings.

Safety first: Disconnect power before removing interior panels or handling sensors.

Steps to address E10:

• 1. Locate the internal air sensor: Inside the ice storage area or near the evaporator, find the small probe or sensor housing connected by two wires.
• 2. Check mounting: Ensure the sensor is properly clipped or mounted and not dangling or touching very cold surfaces directly unless designed to do so.
• 3. Inspect wiring: Follow the sensor cable to the main PCB, checking for cuts, abrasions, or loose connectors. Reseat the plug.
• 4. Test the sensor: Measure resistance at room temperature and compare to the expected NTC curve. Replace the sensor if it reads open or short.
• 5. Replace the sensor: Install a HOMCOM-compatible internal air NTC sensor, routing the cable away from sharp edges and moving parts.
• 6. Reassemble and test: Restore power and run a cycle to confirm that E10 is cleared and the unit operates normally.

Note: Persistent E10 with a known-good sensor indicates a PCB fault that should be handled by a professional.
