How do I fix error code E IS on my LG LF31T6230SW?

1. undefined: 1. Check CON3 connector (Pin 10 to Pin 9) for loose or disconnected connection between Main PCB and ice/icing sensor. 2. undefined: 2. If connector is loose or disconnected, reconnect or repair the connector and retest. 3. undefined: 3. Measure sensor resistance at CON3 Pin 10 to Pin 9. If resistance reads 0 ohms (short circuit), replace the sensor. 4. undefined: 4. Measure sensor resistance at CON3 Pin 10 to Pin 9. If resistance reads open/infinite (open circuit), proceed to step 5. 5. undefined: 5. Compare measured resistance against the temperature-resistance table. If out of range, replace the sensor. 6. undefined: 6. If resistance is within range, explain to customer that the unit is functioning normally. 7. undefined: 7. Check the sensor connection. If the sensor connection is abnormal, replace the refrigerator sensor. If abnormal, reconnect or repair the connector.
