York S1-025-17620-017 Pressure Switch

The York S1-025-17620-017 Pressure Switch is a high-limit safety control designed for precise HVAC system protection. Engineered for high pressure monitoring, this dual-action pressure switch features a fixed 380 PSI open setpoint to prevent compressor damage and a 300 PSI close reset point for automated system recovery. As a genuine York OEM replacement part, it ensures seamless integration and provides the exact electrical specifications required for maintaining HVAC high pressure safety standards in commercial and residential condensing units.

Experienced technicians rely on the York S1-025-17620-017 for its durable, corrosion-resistant construction and fail-safe operational design. This 1/2-inch NPT pressure controller is optimized for refrigerant pressure regulation in harsh environments, effectively preventing high-side over-pressurization during restricted airflow or fan motor failures. By installing this authentic high pressure cutout switch, contractors ensure the long-term reliability of the cooling circuit and maintain peak operational efficiency without the risks associated with universal generic alternatives.

• Industrial Precision: Calibrated for a 380 PSI cutout and a 300 PSI cut-in, providing consistent refrigerant pressure control.
• Direct Compatibility: Engineered as an official replacement for York B3CH090A46B models and other compatible HVAC units.
• Robust Construction: Built to withstand the high temperatures and vibrations of HVAC compressor protection environments.
• Simplified Installation: Standard 1/2-inch connection allows for quick field replacement, reducing labor time and system downtime.

What causes the York S1-025-17620-017 to trip frequently?
Repeated high-pressure cutouts often indicate a blocked condenser coil, a failing condenser fan motor, or an overcharged refrigerant system. Always check for proper airflow before replacing the switch.

Is this switch compatible with non-York systems?
While designed as a York OEM part, it can function in other systems requiring a 380/300 PSI high-pressure safety reset, provided the connection type and electrical ratings match the manufacturer’s technical data.
