How do I fix error code IS E on my LG LFXS28968B?

1. undefined: Check if connector between Main PCB and icing sensor is disconnected or loose. If yes, reconnect or repair the connector. 2. undefined: Check the sensor resistance. If resistance is 0 ohms (sensor shorted), change the sensor. 3. undefined: Check the sensor resistance. If resistance is open/infinity (sensor open), replace the sensor. 4. undefined: If resistance is normal, cross-reference with temperature/resistance table (CON5, 45th pin to 17th pin). If all values pass, explain normal operation to customer.
