Open the access panel in the freezer or evaporator area, where the sensors are usually located. Identify the two main sensors: Ambient Temperature Sensor: Located in the storage compartment, it measures the internal temperature. Evaporator Sensor: Located near the evaporator, it regulates the defrosting process. Defrost Sensor (if applicable to your model): It may be located in the evaporator area and helps detect ice formation. Step 2: Removing the Old Sensors Carefully disconnect the sensors from their connectors or terminals in the circuit. Note the exact position of each sensor to place the new ones in the same location. Use a suitable tool to remove any fasteners or screws holding them in place. Step 3: Installing the New Sensors Insert the new sensors into the same locations as the old ones. Make sure they are properly connected and in good contact with their respective surfaces. Reattach the sensors, ensuring they are securely fastened to prevent movement or disconnection. Step 4: Measuring the Sensors at 24°C Connect a multimeter set to the resistance (Ohms, Ω) scale to test each sensor. At 24°C, NTC (Negative Temperature Coefficient) sensors should show a specific resistance: Ambient sensor: should be in the range of 5 to 10 kΩ. Evaporator sensor: It usually has a resistance similar to the ambient sensor, although this can vary depending on the model (check the manufacturer's specifications). Defrost sensor: It may have a slightly different resistance, depending on its specific function (generally also in the 5 to 10 kΩ range). Step 5: Final Test Once the sensors are installed and measured, reconnect the refrigerator to the power supply. Make sure the refrigerator is working correctly and that the temperature is properly regulated in both compartments. This guide will allow you to replace the sensors in a frost-free refrigerator and check their accuracy before putting it into operation.
