The high pressure switch is a critical refrigerant-circuit safety device that continuously monitors refrigerant discharge pressure. When system pressure exceeds the cutout threshold, the switch opens the control circuit to prevent compressor damage and system failure. A failed or out-of-calibration switch will trigger nuisance high-pressure lockouts, cause repeated no-cool complaints, or — if stuck closed — allow dangerously high pressures to go unchecked.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 395 PSI | Closes at 295 PSI | 240 VAC rated | 6(6)A | 1\/8\" NPT thread | Sensata PS80-03-0018 \/ HK02ZA395A platform\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM switches are factory-calibrated to exact cut-in\/cut-out tolerances.
