The high pressure switch monitors refrigerant circuit pressure on the high side and cuts out the compressor when a dangerous pressure spike is detected — protecting the compressor from catastrophic failure. When this switch fails or trips on a fault, symptoms include sudden compressor shutdown, system lockout codes, or a unit that short-cycles and fails to maintain setpoint. A faulty switch can also fail closed, masking an actual high-pressure condition and causing compressor damage.\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 OEM equivalent | Replaces: 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM switch manufactured to exact factory pressure setpoints (±2%).
