Refrigerator display shows E1 and fridge compartment temperature is too warm or fluctuates.

Safety first: Unplug the refrigerator from the mains before removing any panels or handling wiring. Do not work on live circuits.

Steps to check and address E1:

• 1. Power reset: Unplug the appliance for 5–10 minutes, then plug back in. If E1 clears and does not return, it may have been a transient fault.
• 2. Locate the fridge sensor: The refrigerator (fresh food) NTC is usually clipped to the evaporator cover or mounted on the rear wall/ceiling of the fridge compartment behind a small plastic cover. Remove shelves as needed.
• 3. Inspect the sensor and wiring: Check for broken, pinched, or corroded wires and loose connectors. Reseat the plug at both the sensor and the main PCB (usually at the rear behind a metal or plastic cover).
• 4. Test the sensor (for competent DIYers with a multimeter): With power disconnected, unplug the sensor and measure resistance across its two terminals. A typical NTC will read between 2–20 kΩ depending on temperature. An open circuit (OL) or 0 Ω indicates a failed sensor.
• 5. Replace the sensor if faulty: If readings are out of range or the sensor body is damaged, replace it with the exact Belling-compatible fridge NTC sensor. Clip or tape it back in the original position for correct temperature sensing.
• 6. If sensor and wiring are good: If the sensor tests correctly and wiring is intact, the fault may lie with the main control board. At this point, professional diagnosis is recommended.

Warning: If you are not confident using a multimeter or accessing internal wiring, contact a qualified appliance technician.
