York S1-025-17620-013 Pressure Control

Ensure your refrigeration systems remain within safe operating parameters with the York S1-025-17620-013 Pressure Control. Designed as a rugged OEM replacement part for York and Johnson Controls equipment, this single pressure control is engineered to monitor suction line pressures and prevent compressor damage during low-pressure events. Specifically calibrated for critical refrigerant pressure control, this unit features a fixed setpoint that opens at 7 degrees and closes at 22 degrees, making it an essential safety component for York HVAC systems and light commercial refrigeration units.

For service technicians and contractors, the S1-025-17620-013 offers a direct-fit solution that maintains the original engineering specifications of the B1CH048A25A and similar models. Its low-pressure switch logic provides reliable protection against loss of charge or coil freeze-ups, ensuring the refrigeration control circuit interrupts operation before significant mechanical failure occurs. This part eliminates the guesswork of universal adjustments, providing a laboratory-calibrated response for consistent HVAC performance in demanding environments.

• Precision Calibration: Factory-set to open at 7°F and close at 22°F, ensuring accurate low-pressure cut-out protection.
• OEM Compatibility: A genuine York-Johnson Controls part, guaranteeing a seamless fit into existing wiring harnesses and mounting footprints.
• System Protection: Acts as a primary refrigerant safety switch to prevent compressor overheating and liquid slugging during low-side pressure drops.
• Durable Construction: Built to withstand the vibration and thermal cycling common in residential and commercial HVAC environments.

• What is the primary function of this switch? This is a low-pressure cut-out switch designed to shut down the compressor circuit if the refrigerant pressure falls below the safe operating threshold (7°F).
• Can I use this for high-pressure protection? No, this is specifically a single pressure control for the low-pressure side of the system. For head pressure management, a high-pressure switch with different setpoints is required.
• Is this part adjustable? This model is a fixed-setting OEM pressure control. It is not intended for field adjustments to ensure the system operates within its original design parameters.
