York 025-39909-000 Pressure Control

Maintain precise system parameters and protect vital compressor components with the York 025-39909-000 Pressure Control. Engineered for heavy-duty HVACR applications, this OEM York pressure switch serves as a critical safety limit, featuring factory-calibrated setpoints of 50 PSI Open and 71 PSI Close. This specific pressure range is designed to prevent low-pressure conditions that could lead to evaporator freeze-ups or catastrophic compressor oil slugging in air handlers and condensing units.

The York S1-025-39909-000 is an industrial-strength HVAC control built with high-grade copper and stainless steel internals to ensure long-term reliability under fluctuating thermal loads. This single pressure control is a direct replacement for various M-Series and V-Series ventilators, as well as specific refrigeration circuits requiring 50Op 71Cls specifications. By integrating this HVAC pressure limit switch into your service routine, you ensure the system operates within manufacturer-stipulated refrigerant envelopes, safeguarding the equipment's lifespan and overall mechanical integrity.

• Precise Calibration: Factory-set to 50 PSIG (Open) and 71 PSIG (Close) for accurate low-pressure monitoring.
• Direct OEM Fit: Ensures seamless compatibility with York M-Series and V-Series equipment without field modifications.
• Robust Construction: Designed with industrial materials to withstand high-vibration environments near compressors.
• Critical Protection: Acts as a primary failsafe to prevent system operation during low-charge or restricted-flow conditions.

What is the primary function of the 50Op 71Cls setting?
The control is designed to break the electrical circuit when the suction pressure drops to 50 PSI (Protecting the compressor) and automatically resets when the pressure rises to 71 PSI.

Is the 025-39909-000 compatible with other brands?
This is an official York replacement part; while pressure range specs may overlap with other brands, its physical mounting and electronic leads are optimized specifically for York/Johnson Controls equipment.

Can this switch be used in both heating and cooling cycles?
Yes, as long as the system's pressure requirements match the 50/71 PSI threshold, it can serve as a limit switch for various HVACR cycles.
