The high pressure switch is a critical refrigerant-circuit safety device that monitors system discharge pressure and shuts down the compressor when pressure exceeds safe operating limits. When this switch fails or trips, you'll typically experience nuisance high-pressure lockouts, a compressor that won't start, or fault codes indicating a high-pressure trip event on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 395 PSI | Closes at 295 PSI | 1\/8\" NPT thread connection | 240 VAC rated | Sensata PS80-03-0018 \/ P332-1103 platform | Cross-references: 312926-217, 71267D1, HK02ZA380, HK02ZA396, 19240027\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part manufactured to exact factory pressure tolerances.
