York S1-025-33307-001 Reversing Valve

The York S1-025-33307-001 Reversing Valve is a critical 4-way refrigeration component designed for heat pump flow reversal in York, Coleman, and Luxaire systems. This OEM York replacement part comes complete with a pre-installed solenoid coil, ensuring seamless integration into the 24V control circuit. Engineered to withstand high-pressure differentials typical in R-410A refrigerant systems, this valve features a robust slide mechanism to prevent sticking during seasonal transitions. Technicians should verify line size compatibility and ensures proper heat sinking during brazing to protect internal seals. Whether you are performing a reversing valve troubleshooting procedure or a full system overhaul, this component restores the unit's ability to switch between heating and cooling modes efficiently. Utilizing high-grade copper connections and a precision-wound coil, the S1-025-33307-001 maintains HVAC system performance and reliability under demanding thermal loads.

Key Benefits for Contractors

• Integrated Solenoid Coil: Eliminates the need to source a separate 24V coil, reducing installation time and ensuring electrical compatibility.
• Broad OEM Compatibility: Verified as a direct replacement for various York and Johnson Controls heat pump models.
• High-Pressure Tolerance: Purpose-built to handle the discharge pressures of modern high-efficiency refrigerants.
• Precise Flow Direction: Minimizes bypass leakage between suction and discharge lines to maintain system SEER and EER ratings.

Common Installation Questions

What are the symptoms of a stuck York reversing valve?
Common indicators include the system failing to switch modes, high-side pressure bleeding into the low-side, or the outdoor unit heating up in cooling mode. Always verify coil voltage before assuming a mechanical failure.

Are there specific brazing requirements for this valve?
Yes, use a wet rag or heat-blocking putty on the valve body. Excessive heat can warp the internal slide or damage the synthetic seals, leading to permanent internal bypass or external leaks.

Does this part replace the S1-02533307001?
Yes, this is the current manufacturer-authorized part number for that specific sequence, ensuring an exact fit for the refrigerant piping layout.
