OEM Carrier High Pressure Switch 395/295 PSI — HK02ZA395 for Model PY2PEB036060AA

This OEM Carrier high pressure switch (part number HK02ZA395) is the factory-specified refrigerant-side safety control for the Carrier PY2PEB036060AA packaged unit. The high pressure switch continuously monitors refrigerant discharge pressure and opens the safety circuit when pressure exceeds the cut-out threshold, protecting the compressor from catastrophic over-pressure failure. A failed or out-of-calibration switch will cause the system to lock out on high pressure fault, short-cycle without cooling, or in some cases allow pressure to run dangerously high without tripping — both scenarios damaging the compressor over time.

• Specs: Cut-Out (Open) at 395 PSI | Cut-In (Close) at 295 PSI | Rated 240 VAC | 1/8" NPT male thread | Single-pole normally-closed (SPNC) | Sensata / Pressurestat series PS80
• OEM vs Generic: OEM switches are factory-calibrated to ±2% PSI tolerance, ensuring the compressor is protected at the exact design threshold. Generic switches frequently carry ±10–15% tolerance, meaning they may fail to trip in time — or trip unnecessarily — shortening compressor life and voiding equipment warranties.
• Install difficulty: 2/5 — Recover all refrigerant before removing the switch; never open the refrigerant circuit under pressure. Tools needed: refrigerant recovery machine, adjustable wrench, manifold gauge set, thread sealant (Nylog or equivalent). Always verify system pressures with gauges after reinstall before recharging.
• Warranty & Shipping: Backed by Carrier's 1-year OEM parts warranty. In stock and ships same business day from our warehouse.
