OEM Carrier High Pressure Switch 395/295 PSI — HK02ZA395 for Model PY2PNB060115AB

This OEM Carrier high pressure switch (part number HK02ZA395) is the factory-specified replacement for the Carrier PY2PNB060115AB packaged unit. The high pressure switch is a critical refrigerant-circuit safety device: it continuously monitors system discharge pressure and opens the control circuit to shut down the compressor if pressure climbs to an unsafe level. When this switch fails or trips, the system typically locks out on a high-pressure fault, short-cycles the compressor, or refuses to start — leaving you without cooling or heating on the hottest or coldest days of the year.

• Specs: Opens (cutout) at 395 PSI | Closes (reset) at 295 PSI | 1/8" NPT male thread | Rated 6(6)A at 240 VAC | Pmax 41 Bar | Sensata PS80-03-0018 platform | Auto-reset type
• OEM vs Generic: This is a genuine Carrier OEM part, factory-matched to exact cutout and reset pressures. Aftermarket switches frequently carry ±5–10% pressure tolerances that can allow nuisance trips or — worse — fail to protect the compressor at true high-pressure events.
• Install Difficulty: 2/5 — Recover system refrigerant before removing the switch (EPA 608 required). Tools needed: refrigerant recovery unit, adjustable wrench, 1/8" NPT thread tape, manifold gauge set. Always leak-check the port after reinstallation before recharging.
• Warranty: 1-year OEM factory warranty. Genuine Carrier part. Ships same business day from our warehouse.
