York S1-025-50189-000 Pressure Switch

York S1-025-50189-000 Pressure Switch

The York S1-025-50189-000 Low Pressure Switch is an essential OEM safety component designed to protect the compressor in TH4 series heat pumps and compatible HVAC equipment. Engineering for precision, this low pressure cut-out switch features a 60 PSI open and 30 PSI close setting (60/30), ensuring the system halts operation if refrigerant levels or airflow drop below safe thresholds. Constructed with a durable brass body and utilizes a Single Pole Single Throw (SPST) electrical configuration, this 24V switch provides reliable HVAC compressor protection against coil freezing and mechanical failure caused by low-charge conditions.

For technicians, the York S1-025-50189-000 serves as a direct drop-in replacement, maintaining system integrity and meeting original factory specifications. Its compact design facilitates installation in tight cabinets, while the factory-calibrated setpoints eliminate the need for field adjustments. When troubleshooting short-cycling or system lockouts, verifying the functionality of this 60/30 pressure switch is a standard protocol to prevent permanent compressor damage.

Key Benefits
  • Precise System Protection: Pre-set at 60 PSI Open / 30 PSI Close to prevent operation under hazardous low-pressure conditions.
  • OEM Performance: Genuine York replacement part ensures exact compatibility with TH4 heat pump models.
  • Durable Construction: High-grade brass housing resists corrosion and maintains setpoint accuracy over long-term service.
  • Standard Electrical Integration: 24V SPST design allows for seamless connection to existing control boards.
Common Questions

How do I troubleshoot an S1-025-50189-000 switch?
Use a multimeter to check for continuity. If the system pressure is above 60 PSI but the SPST switch remains open, the internal mechanism is likely fouled or stuck.

What causes this low pressure switch to trip frequently?
Common issues include low refrigerant charge, restricted thermal expansion valves (TXV), or severely clogged air filters reducing evaporator airflow.

Can this part be used on other heat pump brands?
While functionally similar to other 60/30 switches, this part is specifically spec'd for York TH4 heat pumps. Always verify the part number to ensure correct fitting and electrical termination.
