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

1. undefined: Check for loose or disconnected connector between Main PCB and freezer sensor at CON4 pins 18~17. 2. undefined: If connector is loose or disconnected, reconnect or repair the connector. 3. undefined: Measure sensor resistance at CON4 pins 18~17. If resistance is 0 ohm (short), replace the sensor. 4. undefined: If resistance is infinite/open, proceed to check sensor connection harness. 5. undefined: If sensor connection is normal and resistance is open, replace sensor. 6. undefined: Check the temperature-to-resistance table. If resistance does not match expected value for the measured temperature, replace the sensor. 7. undefined: If all checks pass and resistance is normal, explain normal operation to customer. 8. undefined: If sensor connection is faulty, reconnect or repair connector. If PCB is suspect after all checks pass, replace the refrigerator main PCB.
