5. Installation

The installation process typically involves replacing an existing faulty defrost sensor. Specific steps may vary depending on your refrigerator model. Always refer to your refrigerator's service manual for precise instructions regarding component location and removal.

5.1. General Installation Steps

1. Disconnect Power: As stated in the safety section, unplug the refrigerator from the wall outlet.
2. Access Evaporator Compartment: Locate and remove the necessary panels inside the freezer or refrigerator compartment to access the evaporator coils and the existing defrost sensor. This usually involves removing shelves, ice makers, and rear panels.
3. Locate Old Sensor: Identify the old defrost temperature sensor. It is typically clipped onto one of the evaporator coils or positioned nearby.
4. Disconnect Old Sensor: Carefully disconnect the wiring harness from the old sensor. Note the routing of the wires.
5. Remove Old Sensor: Unclip or detach the old sensor from its mounting location.
6. Install New Sensor: Attach the new LICHIFIT DA32-00006W sensor in the same location and orientation as the old one. Ensure it is securely fastened.
7. Connect New Sensor: Connect the wiring harness to the new sensor. Ensure a firm connection.
8. Reassemble: Reinstall all panels, shelves, and other components that were removed.
9. Restore Power: Plug the refrigerator back into the wall outlet.
10. Monitor Operation: Observe the refrigerator's operation for the next 24-48 hours to ensure proper defrosting and temperature regulation.

6. Operating Principles

The 5K DA32-00006W sensor is a thermistor, meaning its electrical resistance changes with temperature. As the temperature inside the refrigerator compartment fluctuates, the sensor's resistance changes. The electronic control board monitors this resistance to determine the internal temperature. When the temperature drops to a certain point, indicating potential frost buildup, the control board uses the sensor's input to activate the defrost heater. Once the defrost cycle is complete and the temperature rises sufficiently, the sensor signals the control board to turn off the heater and resume normal cooling operations.

7. Maintenance

The defrost temperature sensor itself requires no routine maintenance. However, to ensure its longevity and accurate operation, it is recommended to:

• Keep the refrigerator's interior clean to prevent debris from accumulating around the sensor.
• Ensure proper airflow within the refrigerator and freezer compartments by not overpacking them.
• Periodically check for any signs of excessive frost buildup, which could indicate a malfunctioning defrost system, including the sensor.

8. Troubleshooting

If you experience issues with your refrigerator's defrost system after replacing the sensor, consider the following:

8.1. Excessive Frost Buildup

• Check Sensor Connection: Ensure the new sensor is securely connected to the wiring harness.
• Verify Sensor Placement: Confirm the sensor is correctly positioned on the evaporator coil as per your refrigerator's service manual.
• Inspect Other Defrost Components: If frost persists, the issue might lie with other parts of the defrost system, such as the defrost heater or the defrost timer/control board.

8.2. Refrigerator Too Warm/Freezer Too Cold

• Sensor Malfunction: Although new, a faulty sensor can send incorrect temperature readings.
• Airflow Obstruction: Ensure vents are not blocked by food items, which can affect temperature distribution.

For complex issues, it is recommended to consult a professional appliance repair technician.
