The high pressure switch is a critical refrigerant-circuit safety device that monitors system discharge pressure and opens the control circuit when pressure exceeds safe operating limits. When it fails or trips repeatedly, the system will lock out on a high-pressure fault — resulting in no cooling or heating, nuisance shutdowns, or a compressor that refuses to restart.\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 | 1\/8\" NPT male thread | 240 VAC rated | Sensata PS80-03-0018 platform | Supersedes part numbers: 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401, HK02ZA435\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 setpoints.
