Mounted in the high-side refrigerant circuit, this pressure switch continuously monitors system pressure and opens the circuit when pressure exceeds the safe threshold — protecting the compressor from catastrophic damage. When this switch fails or trips repeatedly, you'll experience nuisance lockouts, no-cooling conditions, or a system that immediately shuts down after startup without an obvious refrigerant-side cause.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at \u003cstrong\u003e395 PSI\u003c\/strong\u003e | Closes at \u003cstrong\u003e295 PSI\u003c\/strong\u003e | Sensata PS80 series | 6(6)A @ 240 VAC | PMAX 41B | 1\/8\" NPT male thread connection | SPST normally closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM switch is manufactured to Carrier's exact pressure setpoints (±3% tolerance). Aftermarket alternatives often carry wider tolerances, risking either premature nuisance trips or — more dangerously — failure to open at true overpressure conditions, exposing your compressor to damage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Refrigerant circuit work must be performed by an EPA 608-certified technician.
