Refrigerator shows E1 and fresh food compartment temperature is incorrect or fluctuating.

Safety: Unplug the refrigerator before accessing internal wiring or control boards.

• Locate the fridge sensor: In Cecotec refrigerators, the fresh food NTC sensor is usually behind a small plastic cover on the rear interior wall or near the air outlet from the freezer.
• Visual inspection: Remove the cover and inspect the sensor and its wires. Look for cuts, pinched sections, or signs of moisture ingress.
• Check connector: Trace the sensor wires to the connector (often behind an interior panel or at the top of the cabinet). Ensure the connector is fully seated and not oxidized.
• Basic resistance check (optional): With the fridge unplugged, disconnect the sensor and measure resistance with a multimeter. A typical NTC at room temperature is around 5–10 kΩ. A reading of 0 Ω (short) or infinite (open) indicates a bad sensor.
• Replace sensor if faulty: Order a Cecotec-compatible refrigerator compartment NTC sensor. Swap the sensor, routing the new wire along the original path and securing it away from moving parts or sharp edges.
• Reset and test: Restore power and allow 10–15 minutes. The E1 code should clear automatically if the sensor is detected correctly.
