OEM Carrier High Pressure Switch HK02ZA395 for Model PY2PNB036060AA

This OEM high pressure switch is the factory-specified replacement for the Carrier PY2PNB036060AA packaged unit. The high pressure switch continuously monitors refrigerant-side pressure in the system and opens the control circuit if pressure exceeds the factory-set safety threshold — shutting down the compressor to prevent catastrophic refrigerant-side damage. When this switch fails or trips and won't reset, the system enters a lockout condition: you may see a fault code on the control board, the compressor won't start, or the unit shuts down shortly after each cycle begins.

• Specs: High-pressure cut-out switch | Factory-calibrated trip point | Spade terminal connections | Designed for R-410A refrigerant systems | OEM part number HK02ZA395
• OEM vs Generic: This is a genuine OEM Carrier component manufactured to exact factory pressure-trip and reset tolerances. Aftermarket pressure switches can carry wide calibration tolerances, risking nuisance trips or, worse, inadequate compressor protection — always choose OEM for safety-critical controls.
• Install difficulty: 3/5 — System must be recovered and refrigerant pressure relieved before replacing this switch. Tools needed: refrigerant recovery equipment, manifold gauge set, 1/4" nut driver, needle-nose pliers, and a multimeter to verify continuity post-install. Licensed HVAC technician recommended.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
