How do I fix error code F dS on a LG refrigerators?

1. undefined: 1. Check connector between defrost controller and sensor for loose or disconnected connection. 2. undefined: 2. If connector is loose or disconnected, reconnect or repair the connector and retest. 3. undefined: 3. Measure sensor resistance at CON8 Pin 26 to Pin 25. If resistance reads 0 ohms (short circuit), replace the defrost sensor. 4. undefined: 4. Measure sensor resistance at CON8 Pin 26 to Pin 25. If resistance reads open/infinite (open circuit), replace the refrigerator sensor assembly. 5. undefined: 5. Compare measured resistance against the temperature-resistance table (e.g., 30k ohm at 32°F/0°C). If out of range, replace the sensor. 6. undefined: 6. If all checks pass and resistance is within table range, explain to customer that the unit is functioning normally.
