DA81-06406A - Samsung Refrigerator Sealed System Supplies

This Samsung Refrigerator Sealed System Supplies (DA81-06406A) is a genuine part specifically designed for Samsung refrigerators. It includes essential components like refrigerant, lubricating oil, and desiccant which are critical for the refrigeration cycle to function effectively. These supplies, also known as Lokring, play a pivotal role in maintaining the sealed system's integrity by ensuring refrigerant purity, proper pressure levels, and optimal oil quality. The sealed system contains pre-charged hoses and fittings that have been installed with refrigerant either during manufacture or field service. The lubricating oil circulates within the system to keep the compressor operating smoothly, while the desiccant helps absorb moisture in parts such as the accumulator to prevent corrosion. It's important to note that only trained technicians should perform service on the sealed system to avoid contamination, leaks, or mixing different types of refrigerants, which can lead to operational problems. Symptoms indicating the need for new sealed system supplies include decreased cooling efficiency, unusual noises from the refrigeration unit, or evidence of refrigerant leakage. Before purchasing, customers are advised to verify their refrigerator's model number to ensure compatibility with the DA81-06406A sealed system supplies.
