Refrigerator shows E1; fresh food (fridge) compartment temperature is incorrect or fluctuates.

Safety first: Disconnect the appliance from mains power before accessing internal panels or wiring.

Locate the fridge sensor: On Finlux refrigerators, the fridge NTC sensor is usually behind a small plastic cover on the rear wall of the fresh food compartment or clipped into the liner near the air outlet.

• Visual inspection: Remove the sensor cover. Check if the sensor probe is intact and firmly clipped in place. Look for damage to the thin sensor wires.
• Check connections: Trace the sensor cable as far as possible. Ensure it is not pinched by shelves or panels. At the rear, remove the PCB cover and verify the sensor connector is fully seated on the main control board.
• Basic resistance check (for advanced DIYers): With the fridge unplugged, disconnect the sensor from the PCB and measure resistance with a multimeter. A typical NTC sensor will read between 5–50 kΩ depending on temperature. An open circuit (infinite) or 0 Ω indicates a faulty sensor.
• Replace if faulty: If the sensor is open/shorted or physically damaged, replace it with a Finlux-compatible fridge NTC sensor. Route the new sensor along the original path and avoid sharp bends.
• Reassemble and test: Refit covers, restore power, and allow several hours for temperatures to stabilize. Confirm that the E1 code clears.

Note: If a new sensor does not clear E1, the main control PCB may be misreading the sensor and require replacement.
