York S1-025-42674-000 Control

The York S1-025-42674-000 Control is a precision-engineered low pressure control designed for critical monitoring in residential and commercial HVAC refrigeration systems. This OEM York replacement part features a fixed pressure setting of 60 PSI (open) and 90 PSI (close), ensuring the compressor remains protected against low-suction conditions that can lead to catastrophic motor failure or oil slugging. Built for high-reliability applications, this 60/90 pressure switch integrates seamlessly into the outdoor unit's control loop, functioning as a vital safety limit to maintain system equilibrium.

As a technician, you know that maintaining accurate refrigerant pressure control is non-negotiable for system longevity. This encapsulated switch utilizes a durable sensing element to provide consistent trip points, even in demanding environments. Whether you are performing a reactive repair or a proactive system overhaul, using a genuine HVAC pressure switch like the S1-025-42674-000 ensures the refrigeration components operate within factory-specified parameters, eliminating the guesswork associated with universal aftermarket alternatives. Its compact footprint and rugged design make it the industry standard for Unitary Products equipment maintenance.

• Optimized Compressor Protection: Prevents operation during low-charge scenarios, safeguarding internal motor windings from overheating.
• Factory-Calibrated Accuracy: Features a fixed 60 PSI cut-out and 90 PSI cut-in range for reliable automated cycling.
• Direct OEM Compatibility: Specifically engineered for York, Coleman, and Luxaire air conditioners and heat pumps to ensure a plug-and-play fit.
• Encapsulated Design: Resists moisture and environmental contaminants, ensuring long-term contact integrity in outdoor condenser sections.

• What causes the pressure switch to trip at 60 PSI? A trip at 60 PSI typically indicates a low refrigerant charge, a blocked evaporator coil, or a failing indoor blower motor.
• Can this control be used with R-410A systems? Yes, provided the system's operating logic and safety parameters fall within the 60/90 PSI range for low-side protection.
• Is this a manual or automatic reset switch? The S1-025-42674-000 is an automatic reset control, closing the circuit once pressure rises back to 90 PSI.
