OEM Carrier High Pressure Switch HK02ZA395 — 395/295 PSI for Model PY2PPB060130AB

This OEM Carrier high pressure switch (part number HK02ZA395) is the factory-specified refrigerant-side safety device for the Carrier PY2PPB060130AB packaged unit. The high pressure switch continuously monitors refrigerant discharge pressure and opens the circuit to shut down the compressor the moment pressure exceeds the safe threshold — protecting the compressor from catastrophic damage due to blocked condenser coils, refrigerant overcharge, or failed condenser fan motors. When this switch fails or trips and won't reset, the system will lock out on a high-pressure fault, leaving you with no cooling and a fault code on the control board.

• Specs: Opens at 395 PSI | Closes at 295 PSI | 1/8" NPT male thread fitting | 240 VAC rated | Sensata PS80-03-0018 platform | Replaces: 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401, HK02ZA435
• OEM vs Generic: This is a genuine Carrier OEM part manufactured to exact factory pressure set points (±1%). Aftermarket switches often carry wider tolerances that can allow the compressor to run beyond its safe pressure envelope — a risk not worth taking on a high-value compressor.
• Install difficulty: 2/5 — Requires EPA 608 certification to work in a refrigerant circuit. Recover system refrigerant before disconnecting. Tools needed: 1/8" NPT wrench, thread sealant (Nylog or equivalent), multimeter to confirm open/closed operation post-install. Always confirm system pressure is at zero before removing the old switch.
• Warranty: 1-year OEM factory warranty against defects. In stock and ships the same business day from our warehouse.
