OEM Carrier High Pressure Switch HK02ZA395 — 395/295 PSI for Model PY2PEB048090AA

The Carrier HK02ZA395 is the factory-specified OEM high pressure safety switch for the PY2PEB048090AA packaged unit. Mounted on the high side of the refrigerant circuit, this pressurestat continuously monitors system pressure and cuts power to the compressor the moment refrigerant pressure exceeds the safe operating threshold. When this switch fails or trips, the system will either short-cycle, lockout on a fault code, or refuse to run cooling entirely — symptoms often misdiagnosed as a bad control board or refrigerant leak.

• Specs: Opens at 395 PSI | Closes at 295 PSI | 6(6)A @ 240 VAC | 1/8" NPT male thread | Sensata PS80 platform | PMAX 41B rated
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM pressure switches are factory-calibrated to precise cut-out tolerances. Aftermarket units frequently drift from rated set points, risking compressor damage or nuisance trips.
• Install difficulty: 2/5 — Recover refrigerant charge before removal (EPA 608 required). Tools needed: refrigerant recovery machine, manifold gauges, adjustable wrench, thread sealant (non-hardening). Always verify system pressure is at 0 PSI before unthreading the switch body.
• Warranty: 1-year OEM factory warranty against defects. In-stock — ships same business day from our warehouse.
