OEM Carrier High Pressure Switch HK02ZA395 for Model PY2PEB060115AB

This genuine OEM high pressure switch is the factory-specified safety control for the Carrier PY2PEB060115AB packaged unit. The high pressure switch monitors refrigerant pressure on the high side of the system and cuts power to the compressor the moment pressure exceeds safe operating limits. When this switch fails or trips and won't reset, you'll typically see a system lockout, a non-cooling complaint, or fault codes pointing to high-pressure cutout — symptoms that lead many technicians directly to this component.

• Specs: Opens at 395 PSI | Closes at 295 PSI | 1/8" NPT thread | 240 VAC rated | SPST contact configuration | Sensata PS80-03-0018 / P332-1103 equivalent
• OEM vs Generic: This is a genuine Carrier OEM switch — factory-calibrated to exact cut-in and cut-out pressure thresholds. Aftermarket substitutes often carry wider pressure tolerances, risking nuisance trips or, worse, failure to protect the compressor from damaging overpressure events.
• Install difficulty: 2/5 — System must be recovered and pressure-free before switch removal. Tools needed: refrigerant recovery unit, 1/8" NPT tap wrench, wire stripper, multimeter (verify continuity at rest). Always verify system pressures after reinstallation before restarting.
• Warranty & Shipping: 1-year OEM factory warranty. Ships same business day from our warehouse. Replaces legacy part numbers: 312926-217, 71267D1, HK02ZA380, HK02ZA396, HK02ZA400, HK02ZA401, HK02ZA435.
