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

1. undefined: Step 1: Check if the connector between Main PCB and sensor is disconnected or loose. If yes, reconnect or repair the connector. 2. undefined: Step 2: Measure sensor resistance at CON8 pins 22 to 21. If resistance is 0 Ω (short), replace the sensor. 3. undefined: Step 3: If resistance is open (infinite/OL), proceed to Step 6. 4. undefined: Step 4: Compare measured resistance to the temperature/resistance table. If resistance does not match expected value for ambient temperature, replace the sensor. 5. undefined: Step 5: If resistance is within table spec, explain to customer (normal operation). 6. undefined: Step 6: Check the sensor harness connection between sensor and PCB. If connection is normal, replace the refrigerator main PCB. If connection is not normal, reconnect or repair the connector.
