Replacement defrost sensor compatible with Samsung refrigerators — part numbers DA3200006W and DA3210105R. Designed as a directfit, replacement to restore accurate evaporator temperature sensing and reliable defrost cycle control. Key benefits Restores proper defrost operation: accurately senses evaporator temperature so the control board starts and stops defrost cycles at the correct times, reducing ice buildup. Prevents food spoilage and uneven cooling: correct temperature sensing helps maintain stable freezer and refrigerator temperatures. Improves efficiency and reliability: resolving a failed sensor can reduce excessive runtime and energy use associated with repeated or failed defrost cycles. Simple replacement: designed as a directfit replacement to match original mounting and connections for faster and minimal downtime. Main features and attributes Compatibility: intended for Samsung refrigerators using part numbers DA3200006W and DA3210105R. Verify the part number on your existing sensor before . Functionality: precision thermistorbased defrost sensor that monitors evaporator coil temperature and communicates with the refrigerator control board to manage defrost cycles. Form factor: compact, directfit design that matches OEM mounting locations and connector styles for a straightforward swap. Construction: durable sensing element with insulated wiring and a protective sheath to withstand refrigerator conditions and prolonged operation. Performance: reliable temperature response and stable readings to support consistent defrost timing and overall cooling performance. Installation and maintenance Plugandplay replacement for compatible Samsung units; typical involves removing the evaporator cover, disconnecting the old sensor, and installing the sensor in the same location. No calibration required — the sensor is calibrated to perform as the original part when fitted correctly. Recommended to a faulty defrost sensor promptly to avoid extended ice accumulation, increased energy usage, and potential compressor strain. Typical use cases a failed sensor when your freezer shows excessive ice buildup on the evaporator fins or when defrost cycles do not run, causing frostrelated cooling issues. a refrigerator that frequently runs or cycles improperly due to incorrect evaporator temperature readings, restoring stable temperatures and energy efficiency. Use during routine appliance servicing to renew aging components and prevent future defrostrelated problems in refrigerators that use DA3200006W / DA3210105R sensors. Compatibility reminder Always confirm the part number on your existing sensor or your appliance parts list to ensure compatibility with DA3200006W and DA3210105R before .
