OEM Carrier High Pressure Switch HK02ZA395 — 395/295 PSI for Model PY2PEB060130NB

This genuine OEM high pressure switch is the factory-specified replacement for the Carrier PY2PEB060130NB packaged unit. The high pressure switch is a critical refrigerant-circuit safety device: it monitors refrigerant discharge pressure on the high side of the compressor and cuts power to the compressor the instant pressure exceeds the setpoint, preventing catastrophic compressor failure. Common failure symptoms include the unit tripping into lockout shortly after startup, fault codes indicating high-pressure faults, or repeated compressor short-cycling — especially in hot weather or when airflow is restricted.

• Specs: Opens at 395 PSI | Closes at 295 PSI | 1/8" NPT male thread | 240 VAC rated | Sensata PS80 series | SPST normally closed
• OEM vs Generic: This is a genuine Carrier factory-authorized part (Sensata PS80-03-0018 platform) calibrated to exact OEM pressure setpoints. Generic switches often carry ±5–10% pressure tolerance, which can result in nuisance trips or — worse — inadequate compressor protection. OEM is strongly recommended for commercial packaged units.
• Install difficulty: 2/5 — Always recover refrigerant and depressurize the system before replacing a high-pressure switch. Tools needed: manifold gauge set, refrigerant recovery unit, adjustable wrench, thread sealant (not PTFE tape). Verify new switch orientation matches the original before torquing. Recharge to factory spec after installation.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse in original Carrier packaging.
