OEM Carrier High Pressure Switch HK02ZA395 — 395/295 PSI for Model PY1PPB060115AAAA

This is the genuine OEM Carrier high pressure switch (part number HK02ZA395), factory-specified for the Carrier PY1PPB060115AAAA packaged heat pump unit. The high pressure switch is a critical refrigerant-circuit safety device: it monitors refrigerant discharge pressure and opens the control circuit if pressure exceeds the cut-out threshold, shutting down the compressor to prevent catastrophic failure. When this switch fails or trips repeatedly, you'll see symptoms including nuisance lockouts, compressor short-cycling, system fault codes indicating high-pressure trips, or a unit that simply won't run even though refrigerant charge appears normal.

• Specs: Cut-out (Open) at 395 PSI | Cut-in (Close) at 295 PSI | Rated 6(6)A @ 240 VAC | Sensata PS80 series | 1/8" NPT male fitting | Quick-connect electrical terminals | PMAX 41 bar | CE / EN60730-2-6 certified
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket clone. OEM switches are calibrated to exact PSI setpoints (±2%), ensuring your compressor is protected at the correct threshold. Generic substitutes often carry ±5–10% tolerances, risking either nuisance trips or inadequate compressor protection.
• Install Difficulty: 2/5 — Recover refrigerant before removing the switch (EPA 608 required). Tools needed: manifold gauge set, 1-1/16" open-end wrench, refrigerant-rated thread sealant, multimeter. Always leak-check after installation and verify set-point continuity before recharging. Tag and lockout the system before beginning work.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before 3 PM local time. Also replaces legacy Carrier part numbers: 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401, HK02ZA435, HK02ZA500, HK02ZA501.
