OEM Carrier High Pressure Switch HK02ZA395 for Model PY2PPB060115AB

This is the genuine OEM Carrier high pressure switch (part number HK02ZA395), factory-specified for the Carrier PY2PPB060115AB packaged unit. The high pressure switch is a critical refrigerant-circuit safety device that monitors system discharge pressure and cuts power to the compressor if pressures exceed safe operating limits. When this switch fails or becomes faulty, you'll experience symptoms such as nuisance high-pressure lockouts, compressor short-cycling, system fault codes, or an inability to maintain cooling even in normal ambient conditions.

• Specs: Opens at 395 PSI | Closes at 295 PSI | 240 VAC rated | 1/8" NPT thread connection | Sensata PS80-03-0018 platform | PMAX 41B | Replaces HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401, HK02ZA435, 312926-217, 71267D1, and more
• OEM vs Generic: This OEM switch is factory-calibrated to exact Carrier cut-out and cut-in pressure specifications. Aftermarket alternatives often carry wider pressure tolerances, which can allow compressor operation outside safe limits — risking compressor damage or voiding equipment warranties.
• Install Difficulty: 3/5 — Always recover refrigerant before removing a refrigerant-circuit pressure switch. Tools required: refrigerant recovery machine, manifold gauge set, 1/8" NPT wrench, leak-check solution. Work must be performed by an EPA 608-certified technician. Re-check system pressures and verify switch function after installation.
• Warranty: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PY2PPB060115AB packaged unit. Verify your existing switch's cut-out PSI rating and thread size on the data plate or wiring diagram before ordering. Our parts specialists are available to confirm fitment before you buy.
