York S1-025-22740-000 Pressure Control

The York S1-025-22740-000 Pressure Control is a critical high-limit safety component designed for precise refrigerant management in commercial and residential HVAC systems. Engineered as a Single Pole Single Throw (SPST) switch, this OEM part is calibrated to open the electrical circuit at 325 PSI and automatically close at 225 PSI. This pressure regulation ensures that your compressor and high-side components remain within safe operating parameters, preventing mechanical failure due to over-pressurization. Featuring a robust build typical of York HVAC parts, this refrigerant pressure switch integrates seamlessly into existing control loops. For veteran technicians, the 325 PSI open 225 PSI close setpoints offer reliable high-pressure protection across various R-410A and R-22 applications. Utilizing a genuine S1-025-22740-000 ensures exact electrical matching and physical fitment, reducing diagnostic callbacks and maintaining system efficiency during high-load conditions.

• Precise Calibration: Factory-set 325 PSI high-limit trip point prevents equipment damage without the drift common in aftermarket controls.
• Heavy-Duty SPST Configuration: Simplifies wiring into the safety string for reliable compressor lockout.
• Automatic Reset: Resumes operation at 225 PSI to restore cooling cycles once system pressures stabilize.
• OEM Compatibility: Guaranteed fit for York, Luxaire, and Coleman units requiring the 025-22740-000 specification.

What causes this switch to trip at 325 PSI?
Usually, a trip at the 325 PSI threshold indicates restricted airflow over the condenser coil, a failed condenser fan motor, or a refrigerant overcharge.

Is this a manual or automatic reset switch?
This specific model functions with an automatic reset, closing the circuit once the high-side pressure drops to 225 PSI.

Can this be used as a low-pressure cut-out?
No, this control is specifically calibrated for high-pressure limits. Using it for low-pressure monitoring would result in improper system cycling.
