How do I fix error code F dS on a LG refrigerators?

1. undefined: Check for loose connection between Main PCB, Defrost Controller, and Sensor at CON4 pins 22-21. 2. undefined: If connector is disconnected or loose, reconnect or repair the connector. 3. undefined: Check sensor resistance at CON4 pins 22-21. If resistance reads 0 ohm (sensor short), replace the sensor. 4. undefined: Check sensor resistance. If resistance reads OL/infinity (sensor open), replace the sensor. 5. undefined: Check temperature vs. resistance table for normal values (at 23F/-5C expect 38k, at 50F/10C expect 19.5k). 6. undefined: If temperature vs. resistance correlation is normal, no problem — explain to customer.
