Customer Questions and Answers for Refrigerator Temperature Sensor by Samsung

Hello Dan, and thank you for your question. Here’s how you can check the humidity sensor circuit: Unplug the power cord. Access the main control and disconnect the wire connection CN30. Test resistance between the wires at pin 1 and pin 3 of that connector. If the meter shows open line (OL): there’s a broken or loose wire, most likely at the door hinge. If you do get a resistance reading: that points to the main control DA94-02663D as the cause of failure.
