OEM Carrier High Pressure Switch HK02ZA395 — 395/295 PSI for Model SPACCYCPCNTRLS001A00

This is the genuine OEM high pressure safety switch (part number HK02ZA395) factory-specified for the Carrier SPACCYCPCNTRLS001A00 system. The high pressure switch is a critical refrigerant-circuit safety device: it monitors refrigerant discharge pressure and cuts power to the compressor if pressure rises to an unsafe level. When this switch fails or trips, your system may lock out on a fault code, short-cycle immediately after startup, or refuse to run altogether — protecting the compressor from catastrophic overpressure damage.

• Specs: Opens at 395 PSI | Closes at 295 PSI | 6(6)A 240VAC | 1/8"-Fine NPT thread | Sensata PS80 series | 2-blade quick-connect terminals | PMAX 428 PSI
• OEM vs Generic: This is a genuine Carrier/Sensata factory part with precision-calibrated trip points. Aftermarket switches often carry ±5–10% pressure tolerances, which can allow unsafe pressures to go unchecked or cause false nuisance trips that shut down a properly operating system.
• Install Difficulty: 2/5 — Recover all refrigerant before opening the high-side circuit. Tools needed: refrigerant recovery machine, manifold gauge set, adjustable wrench, thread sealant (non-hardening). Requires EPA 608 certification for refrigerant handling. Always leak-check after installation.
• Warranty & Shipping: 1-year OEM manufacturer warranty. In stock — ships same business day from our warehouse.
