The DA32-10104N is a newer revised version of other defrost and temperature sensors on a Samsung Refrigerator. It is approximately 9", and the Molex harness style should be noted. If this part goes bad in your refrigerator, it can cause temperatures to be erratic, or too high or low, depending on how it failed, as well as premature defrost termination. A typical sensor such as this one should measure 5,000 ohms @ 77*F when tested with a multimeter. If the number goes above or below that by 10%, its likely bad, causing many issues for your refrigerator.
