Replacing it with a PSC motor would require a complete control system overhaul and would sacrifice the system's SEER rating
Enhanced Combustion Efficiency: Precision airflow calibration optimizes the oxygen-to-fuel mix for cleaner
while the high-contrast terminal designations reduce installation errors during high-stress service calls
Durable Construction: High-strength metallic composition resists deformation under constant thermal and mechanical load
York S1-025-50188-000 Pressure Switch 320788-703 Replacing it with a PSCThe York S1 025 50188 000 is an OEM high pressure switch engineered for critical system protection in residential and commercial HVAC equipment. Traditionally found in R 410A systems, this normally closed switch monitors head pressure to prevent compressor damage and mechanical failure. It features a factory calibrated 650 PSI cut out threshold, which opens the electrical circuit when internal pressures exceed safe limits, and a 450 PSI cut in reset
