This refrigerant-side safety device continuously monitors system discharge pressure, opening the control circuit at \u003cstrong\u003e395 PSI\u003c\/strong\u003e and resetting at \u003cstrong\u003e295 PSI\u003c\/strong\u003e to protect the compressor from catastrophic over-pressure damage. When this switch fails or trips without resetting, the unit will lock out on a high-pressure fault — often presenting as a no-cool condition, repeated compressor short-cycling, or a fault code on the thermostat or control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Open (trip) pressure: 395 PSI | Close (reset) pressure: 295 PSI | Voltage: 240 VAC | Current: 6(6)A | Connection: 1\/8\"-NPT fine thread | Terminal: Quick-connect blade | Manufactured by Sensata (Pressurestat PS80-03-0018)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This genuine Carrier Factory Authorized Part is manufactured to exact OEM trip-point tolerances. Aftermarket substitutes frequently deviate from the 395\/295 PSI setpoints, risking either nuisance trips under normal operating pressure or — more dangerously — failure to trip during a true over-pressure event, leading to compressor failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Recover all refrigerant and verify system is depressurized to 0 PSI before removing the switch. Tools needed: refrigerant recovery machine, manifold gauges, 1\" open-end wrench, thread sealant (use PTFE tape rated for refrigerant).
