DA81-06405A - Samsung Refrigerator Sealed System Supplies

This Sealed System Supplies kit (DA81-06405A) is a genuine Samsung part, designed specifically for Samsung refrigerators. It includes pre-charged hoses and fittings with refrigerant, lubricating oil, and desiccant. The desiccant absorbs moisture in components such as the accumulator to prevent corrosion of the refrigerant. The kit also facilitates the lubrication of the compressor through oil circulation, crucial for the refrigeration cycle to function properly. Known for its use in field service or during manufacture, it comes equipped with refrigerant already installed. This kit, also known as Lokring, is essential for any repairs or maintenance involving the sealed system, which encompasses the transfer and preservation of refrigerant, lubricating oil, and ensuring moisture absorption to maintain system integrity.

The operation of the sealed system involves a delicate balance. The refrigerant enables the refrigeration cycle, while the oil lubricates the compressor, and the desiccant keeps moisture away from critical parts to avoid corrosion. Field repairs of this system require specialized recovery and recharge tools to safely transfer refrigerant and maintain oil quality and refrigerant purity. Contamination, refrigerant leaks, or mixing different types of refrigerants can severely impact the system. Due to the complexity and necessity for precision in maintaining the sealed system, only trained technicians should undertake any service task to ensure the refrigerant's purity, pressure, and the quality of oil are upheld. Symptoms indicating the need for this Sealed System Supplies kit may include decreased refrigeration efficiency or notable leaks within the system, signaling potential contamination or issues with refrigerant levels. Before purchasing, customers are advised to confirm their refrigerator's model number matches this part to ensure compatibility.
