Refrigerator display shows E10 and the door alarm behaves abnormally (alarm even when doors are closed).

Safety: Disconnect power before removing door switch assemblies.

• Identify door switches: Cecotec refrigerators may use mechanical plunger switches in the frame or magnetic reed sensors hidden in the liner.
• Check door alignment: Ensure doors close fully and gaskets make uniform contact. Adjust leveling feet if doors are sagging.
• Test switch: For plunger switches, press the switch by hand and listen for a click. For magnetic sensors, place a magnet near the sensor location and see if the interior light turns off (after restoring power briefly).
• Inspect wiring: On models with wiring through the top hinge, check for pinched or broken wires.
• Replace faulty switch: Install a Cecotec-compatible door switch or sensor. Ensure it is firmly seated and aligned with the door magnet (if used).
• Verify operation: Restore power and confirm that the interior light and door alarm behave normally and E10 clears.
