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

1. undefined: Check if connector between Main PCB and sensor is disconnected or loose; if yes, reconnect or repair the connector and retest. 2. undefined: With power OFF, measure resistance at CON8 22nd Pin to 21st Pin. If resistance is 0 Ohm (short), replace the freezer sensor. 3. undefined: If resistance is open/infinite (OL), go to step 6. 4. undefined: If resistance reads a value, check it against the temperature-resistance table. If the value does not match expected resistance for the current temperature, replace the sensor. 5. undefined: If resistance matches expected value, the sensor is good; explain normal operation to customer. 6. undefined: Check the sensor wire harness routing and connection integrity; if connection is normal, replace the refrigerator main PCB.
