How do I fix error code E FS on a LG refrigerators?

1. undefined: Check for loose or disconnected connector between Main PCB and sensor; if disconnected, reconnect or repair connector. 2. undefined: Measure sensor resistance at CON8 pins 22–21. If resistance reads 0 ohms (sensor short), replace the sensor. 3. undefined: If resistance reads open/infinite (sensor open), proceed to step 6. 4. undefined: Compare measured resistance to temperature/resistance table. If values do not match, replace the sensor. 5. undefined: If values are within spec, explain to customer — unit is operating normally. 6. undefined: Check physical sensor connection integrity. If connection is normal, replace the refrigerator main PCB. If connection is faulty, reconnect or repair the connector.
