{"product_id":"db96-09949a-air-conditioner-assembly-eev-valve","title":"Samsung Air Conditioner Assembly EEV Valve - DB96-09949A","description":"\u003cp\u003eRestore the precision refrigerant control and cooling efficiency of your outdoor unit with the Samsung Air Conditioner Electronic Expansion Valve (EEV) Assembly DB96-09949A. This assembly is a critical metering device that regulates the flow of refrigerant into the evaporator coil. Unlike standard fixed-orifice expansion valves, this electronic version uses a stepper motor to make micro-adjustments to the refrigerant flow based on data from the system's temperature and pressure sensors. This ensures optimal cooling performance, prevents liquid slugging of the compressor, and maximizes energy efficiency. A failing EEV often causes the system to underperform, freeze up, or trigger \"high discharge temperature\" and \"refrigerant cycle\" error codes.\u003c\/p\u003e \n\n\u003cp\u003eThe DB96-09949A assembly includes the high-precision valve body and the necessary copper tailpipes for a secure connection to the refrigerant lines. It is designed to handle high-pressure fluctuations and provide a linear response to the control board's signals, ensuring a stable and comfortable indoor environment.\u003c\/p\u003e \n\n\u003cp\u003eInstallation \/ Replacement Instructions:\u003c\/p\u003e \n\n\u003cp\u003e1. Safety and Preparation: This repair involves the refrigerant system. Professional HVAC certification is typically required to recover and recharge refrigerant. Turn off the power at the main circuit breaker. \u003cbr\u003e\n2. Recover Refrigerant: Use a recovery machine to safely remove the refrigerant from the system according to local environmental regulations. \u003cbr\u003e\n3. Access the Valve: Remove the side and top panels of the outdoor condenser unit. Locate the EEV assembly, which is usually found near the compressor and the liquid line service valve. \u003cbr\u003e\n4. Remove the Coil: Unplug the electrical connector and slide the EEV stepper motor coil off the valve body. Set it aside to keep it away from the heat of the brazing torch. \u003cbr\u003e\n5. Unbraze the Assembly: Use an oxy-acetylene torch to unbraze the copper connections of the old DB96-09949A. Use a wet rag or heat-sink paste on nearby sensitive components to prevent heat damage. \u003cbr\u003e\n6. Install the New Valve: Position the new EEV assembly and braze it into the lines. Ensure a nitrogen purge is used during brazing to prevent internal oxidation. \u003cbr\u003e\n7. Vacuum and Recharge: Perform a deep vacuum on the system to remove moisture and air. Once the vacuum is held, recharge the system with the factory-specified amount of refrigerant. \u003cbr\u003e\n8. Test Operation: Restore power and run the unit. Verify that the EEV coil is modulating correctly and that the refrigerant pressures are within the normal operating range.\u003c\/p\u003e \n\n\u003cp\u003eCompatible with select Samsung inverter-driven outdoor units, this OEM-quality EEV assembly is essential for restoring the sophisticated refrigerant management required for modern HVAC performance.\u003c\/p\u003e \n\n\u003cp\u003eKey Features: \u003cbr\u003e\n• AC Electronic Expansion Valve – Part number DB96-09949A \u003cbr\u003e\n• Precision Refrigerant Metering – Modulates flow for maximum cooling efficiency and compressor protection \u003cbr\u003e\n• Linear Stepper Motor Control – Responds accurately to real-time system demands \u003cbr\u003e\n• High-Grade Copper Construction – Designed for durable, leak-free brazed connections \u003cbr\u003e\n• Compatible with Select Samsung Models – Precision-engineered for specific system logic and pressures \u003cbr\u003e\n• OEM-Quality Part – Restores factory-standard refrigerant cycle performance and reliability\u003c\/p\u003e","brand":"Samsung","offers":[{"title":"Default Title","offer_id":37088494387356,"sku":"DB96-09949A","price":294.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/samsungpartsusa.com\/products\/db96-09949a-air-conditioner-assembly-eev-valve","provider":"Samsung Parts USA","version":"1.0","type":"link"}
