The DA32-00006Q defrost sensor is a genuine Samsung OEM part for your refrigerator. It monitors the temperature of the evaporator coil and communicates with the electronic control board to maintain optimal cooling cycles. If your refrigerator isn't cooling properly or is frosting over, this sensor might be the issue. Always unplug your appliance and wear work gloves during installation to protect your hands. Before purchasing, check your device's model number for compatibility.
