Mounted on the high side of the refrigerant circuit, this switch continuously monitors system pressure and opens the compressor circuit if pressure exceeds the factory-rated threshold — protecting your compressor and refrigerant circuit from catastrophic failure. Common symptoms of a failed high pressure switch include the system locking out on a high-pressure fault, the compressor shutting down unexpectedly during high ambient temperatures, or the unit failing to cool altogether despite the outdoor fan running normally.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 395 PSI | Closes at 295 PSI | 240 VAC | 6(6)A | 1\/8\" NPT thread | Sensata PS80 series platform | Cross-reference: HK02ZA395A, PS80-03-0018, 406-300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part — factory-calibrated to exact cutout and cut-in pressures. Aftermarket switches often carry wider pressure tolerances, which can allow the compressor to run outside safe operating limits or trip nuisance lockouts, shortening system life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Refrigerant recovery is \u003cstrong\u003enot\u003c\/strong\u003e required for switch replacement if system pressure is safely relieved through the service port first.
