1. undefined: Check if connector between Main PCB and refrigerator sensor is disconnected or loose; if yes, reconnect or repair and retest. 2. undefined: With power OFF, measure resistance at CON8 20th Pin to 19th Pin. If resistance is 0 Ohm (short), replace the refrigerator sensor. 3. undefined: If resistance is open/infinite (OL), go to step 6. 4. undefined: If a value is present, compare against the temperature-resistance table for current ambient temperature. If mismatch, replace the sensor. 5. undefined: If resistance is correct, sensor is good; explain to customer. 6. undefined: Check the sensor connection harness. If the sensor connection is normal, replace the refrigerator main PCB.
