OEM Carrier High Pressure Switch HK02ZA395 for Model PH2PPB060000AB

This OEM high pressure safety switch is the factory-specified replacement for the Carrier PH2PPB060000AB heat pump system. The high pressure switch continuously monitors refrigerant pressure on the high side of the refrigeration circuit. When system pressure exceeds the factory-set limit of 395 PSI, the switch opens and shuts down the compressor to prevent catastrophic overcharge damage, refrigerant line failure, or compressor burnout. If your system is tripping on high-pressure lockout, short-cycling, or refusing to run the compressor, a failed or nuisance-tripping high pressure switch is a primary suspect.

• Specs: Opens at 395 PSI | Closes at 295 PSI | 1/8" NPT fitting | 240 VAC rated | SPST normally closed | Replaces P/N 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401
• OEM vs Generic: This is a genuine Carrier OEM part (Sensata PS80 platform), factory-calibrated to exact open/close PSI setpoints. Aftermarket switches often drift ±10–15 PSI from spec, risking compressor damage or nuisance shutdowns.
• Install difficulty: 3/5 — Refrigerant recovery is required before replacing this switch. A licensed EPA 608-certified technician should perform this repair. Tools needed: manifold gauge set, refrigerant recovery equipment, adjustable wrench, leak detector.
• Warranty: 1-year OEM factory warranty. Sold individually. Ships same business day from our warehouse stock.

Compatibility: Fits Carrier model PH2PPB060000AB packaged heat pump. Always verify your unit's data plate and existing switch PSI setpoints before ordering — multiple pressure switch variants exist for this model series (see also HK02ZB044 low pressure switch). Questions about fitment? Our parts team verifies compatibility before you order — ships same day.
