OEM Carrier High Pressure Switch HK02ZA395 — 395/295 PSI for Model PY2PPB060130NB

This is the factory OEM replacement high pressure switch for the Carrier PY2PPB060130NB packaged unit. The high pressure switch is a critical refrigerant-side safety device that continuously monitors system discharge pressure. When refrigerant pressure exceeds the cut-out threshold, the switch opens the control circuit, shutting down the compressor to prevent catastrophic failure. A faulty high pressure switch can cause nuisance lockouts on a normal charge, fail to protect a truly over-pressured system, or prevent the unit from starting altogether. Always verify refrigerant charge and airflow before condemning this switch.

• Specs: Opens (cut-out) at 395 PSI | Closes (cut-in) at 295 PSI | 1/8" NPT thread connection | 240 VAC rated | SPST normally-closed | Sensata PS80-03-0018 platform
• OEM vs Generic: This genuine Carrier OEM switch is factory-calibrated to exact cut-out and cut-in pressures. Aftermarket substitutes often carry ±5–10% pressure tolerance variation, risking either false trips or under-protection of the compressor.
• Install difficulty: 2/5 — Recover all refrigerant before disconnecting the pressure switch. Tools needed: refrigerant recovery machine, manifold gauges, 1/8" NPT fitting wrench, needle-nose pliers. Photograph wiring before removal. Recharge and leak-check after installation.
• Warranty & Shipping: 1-year OEM factory warranty against defects. Ships same business day from our warehouse — get your system back online fast.
