OEM Carrier High Pressure Switch 395/295 PSI — HK02ZA395 for Model PY2PEB042060AB

This is the factory-original OEM high pressure switch (part number HK02ZA395) for the Carrier PY2PEB042060AB packaged unit. Manufactured by Sensata, this SPST pressurestat continuously monitors refrigerant discharge pressure on the high side of the refrigeration circuit. When head pressure exceeds the factory-set cutout threshold, the switch opens the control circuit to shut down the compressor — protecting it from catastrophic damage due to blocked condenser coils, overcharge, or high ambient conditions. When the system faults, you'll typically see the unit locking out on a high-pressure fault code, short-cycling at startup, or failing to cool while the outdoor fan continues to run.

• Specs: Opens at 395 PSI | Closes at 295 PSI | SPST (Normally Closed) | 24V / 2A control circuit | 1/8"-NPT refrigerant port | 42" lead length | Quick-connect electrical terminals | 240 VAC rated | Manufactured by Sensata (Carrier Factory Authorized)
• OEM vs Generic: This is the genuine Carrier/Sensata OEM switch, not an aftermarket clone. OEM units are factory-calibrated to exact PSI setpoints — generic switches frequently have ±5–10% PSI variance that can allow unsafe head pressure before cutoff or cause nuisance trips at normal operating pressure.
• Install difficulty: 2/5 — Requires recovery of refrigerant before replacing the switch if the port is in a live refrigerant line. Tools needed: manifold gauge set, refrigerant recovery machine, adjustable wrench, and a multimeter to confirm switch continuity before and after replacement. Always follow EPA 608 protocols. Photograph all wire connections before disconnecting.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3 PM local time.
