Parts for Ge NS17H30SA451A: Room Air Conditioner Parts

An expansion check valve for R-410A refrigeration systems that helps regulate refrigerant flow and prevent reverse flow for more consistent cooling performance. Designed as a direct replacement part for the sealed refrigerant circuit. What it does:

• Controls metered refrigerant flow into the evaporator and helps maintain system pressure balance
• Prevents reverse refrigerant flow that can reduce cooling efficiency
• Can reduce symptoms such as reduced cooling capacity, uneven cooling, or icing in the evaporator
• Works as part of the sealed refrigeration loop in air conditioners and heat pumps using R-410A

• Recover refrigerant and depressurize the system before removal to comply with EPA rules
• May require brazing or sealed-system service; follow OEM assembly and leak-test procedures
• Recharge to manufacturer refrigerant and oil specifications

This 3/4 in. service valve replaces a worn or leaking shutoff valve to restore reliable flow control to the appliance. It's intended for service-level repair where the original valve is corroded, stuck, or leaking. What it does

• Provides on/off flow control for the appliance's water/gas line (as applicable)
• Stops leaks caused by failed or corroded original valves
• Allows technicians to isolate the supply for maintenance or component replacement
• Helps restore proper operation when symptoms include visible leaks, no shutoff, or intermittent flow

• One 3/4 in. service valve

• Recommend shutting off main supply and relieving pressure before removal or installation
• Use correct fittings and thread sealant or tape rated for the media (water or gas) per OEM instructions
• Tighten fittings to manufacturer torque; avoid overtightening to prevent damage
