OEM Carrier High Pressure Switch HK02ZA395 — 395/295 PSI for Model PY2PEB060090AB

This is the genuine OEM high-pressure safety switch (part number HK02ZA395) for the Carrier PY2PEB060090AB packaged heat pump system. The high-pressure switch is a critical refrigeration safety device that monitors refrigerant pressure on the high side of the system. When discharge pressure exceeds the factory-set cutout threshold, the switch opens its contacts and shuts down the compressor to prevent catastrophic damage. A failed or stuck-open switch results in a hard lockout, a no-cooling fault code, or a system that trips on the first call for cooling — especially in high-ambient conditions.

• Specs: Opens (cutout) at 395 PSI | Closes (reset) at 295 PSI | 1/8" NPT thread connection | Sensata PS80-03-0018 platform | 6(6)A @ 240 VAC | PMAX 41 Bar
• OEM vs Generic: OEM Carrier switches are factory-calibrated to exact PSI setpoints. Aftermarket substitutes often carry ±5–10% pressure tolerances, risking nuisance trips or — more dangerously — failure to protect the compressor at true over-pressure conditions.
• Install Difficulty: 2/5 — Recover all refrigerant before removing the switch (EPA 608 required). Tools needed: manifold gauge set, refrigerant recovery machine, adjustable wrench, thread sealant. Photograph and label all wiring before disconnecting. Leak-test after reinstallation.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
