The high pressure switch is a critical refrigerant-circuit safety device: it continuously monitors refrigerant discharge pressure and opens the circuit to shut down the compressor if pressure exceeds the safe threshold. When this switch fails or trips repeatedly, you'll see symptoms like nuisance high-pressure lockouts, compressor short-cycling, or a system that won't run despite normal operating conditions. Replacing a faulty switch with the correct OEM part restores factory-calibrated protection and prevents compressor damage from over-pressurization.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at \u003cstrong\u003e395 PSI\u003c\/strong\u003e | Closes (resets) at \u003cstrong\u003e295 PSI\u003c\/strong\u003e | 1\/8\" NPT thread | Rated 6(6)A at 240 VAC | Sensata PS80-03-0018 platform | PMAX 41B | Replaces: 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401, and additional superseded part numbers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a \u003cstrong\u003egenuine Carrier OEM part\u003c\/strong\u003e — factory-calibrated to exact 395\/295 PSI trip points.
