Description
The York S1-025-50188-000 is an OEM high pressure switch engineered to protect refrigerant circuits in York HVAC systems. Designed with a cut-out pressure of 650 PSI and a cut-in pressure of 450 PSI, this switch continuously monitors system pressure and interrupts compressor operation when unsafe high-side pressure levels are detected — helping prevent costly compressor damage and system failures.
How It Works
When refrigerant system pressure rises to the 650 PSI cut-out threshold, the switch opens the control circuit, shutting down the compressor to prevent damage. Once pressure drops back to the 450 PSI cut-in point, the switch resets and allows normal operation to resume. This pressure differential helps ensure stable, reliable compressor cycling.
