York S1-025-33305-048 Pressure Control

The York S1-025-33305-048 Pressure Control is a critical safety and operational component designed for high-pressure monitoring in HVACR systems. Built for heavy-duty performance, this high-pressure switch features specific factory-set limits: it is configured to open at 400 psi and close at 300 psi. This precise differential ensures that your condensing unit or heat pump operates within safe refrigerant pressure parameters, preventing compressor damage due to excessive head pressure. Rated for 240 VAC, this hermetically sealed control provides the durability required for demanding commercial and residential environments.

As an OEM York replacement part, the S1-025-33305-048 is engineered for seamless HVAC system compatibility with specific models, including the York AC060X1222A series. Its compact footprint, measuring approximately 3.2” in length and 1.8” in height, allows for straightforward installation in tight control boxes. Whether you are dealing with refrigerant pressure management or replacing a failed high-limit switch, this component ensures the reliability and professional-grade performance expected in a York HVACR setup.

• Precise Pressure Calibrations: Features a factory-set 400 PSI open and 300 PSI close threshold for accurate high-pressure protection.
• OEM Reliability: Genuine York HVAC part ensures exact fitment and restores original system performance without the risks of universal aftermarket switches.
• Wide Compatibility: Specifically designed for York, Luxaire, and Coleman equipment, supporting various refrigerant pressure control applications.
• Durable Construction: Rated for 240V systems, providing long-term stability under high electrical and thermal stress.

What happens if my pressure switch is stuck open?
If the high-pressure control remains open at 400 PSI, the system will trigger a safety lockout to protect the compressor. This usually points to a condenser fan failure, a dirty coil, or an overcharge in the refrigerant system.

Can this part be used in 120V circuits?
While rated for up to 240 VAC, always verify your specific control board voltage requirements and wiring diagram. This pressure switch is primarily used in 208/230V residential and commercial condensing units.

Is this a manual or automatic reset switch?
The York S1-025-33305-048 is an automatic reset control, meaning it will re-close the circuit once the internal pressure drops back to the 300 PSI setpoint.
