OEM Carrier High Pressure Switch HK02ZA395 — 395/295 PSI for Model PY1PPB060130AAAA

The Carrier HK02ZA395 is the factory-specified OEM high pressure switch for the PY1PPB060130AAAA packaged unit. This critical safety device continuously monitors refrigerant circuit pressure on the high side. When refrigerant pressure exceeds the cutout threshold — caused by a dirty condenser coil, failed condenser fan motor, refrigerant overcharge, or blocked airflow — the switch opens the control circuit and shuts down the compressor to prevent catastrophic mechanical failure. Symptoms of a failed high pressure switch include nuisance high-pressure lockouts, a system that trips immediately on startup, or a unit that runs briefly then shuts off with a fault code indicating high pressure.

• Specs: Opens at 395 PSI | Closes at 295 PSI | 1/8" NPT male connection | 240 VAC rated | SPST normally closed | Sensata PS80 series (OEM: HK02ZA395A)
• OEM vs Generic: This is a genuine Carrier OEM part manufactured to factory pressure tolerances. Generic aftermarket switches frequently carry wider cutout variance, risking either nuisance trips or — more dangerously — failing to protect the compressor at true overpressure conditions.
• Install difficulty: 2/5 — Recover all refrigerant before replacing. Tools needed: refrigerant recovery machine, 1/8" NPT fitting wrench, manifold gauges, leak-check solution. Always tag out the unit at the disconnect before starting work. Reconnect and verify cutout pressure with gauges after install.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM EST.
