OEM Carrier High Pressure Switch HK02ZA395 — 395/295 PSI for Model PY2PEB060115AA

This OEM high pressure switch is the factory-specified safety control for the Carrier PY2PEB060115AA packaged unit. Its job is critical: it continuously monitors refrigerant system pressure on the high side and cuts power to the compressor the moment pressure exceeds the safe threshold. When this switch fails or trips repeatedly, the system will lock out on a high-pressure fault, resulting in a no-cooling condition, nuisance compressor shutdowns, or a unit that won't restart without a manual reset. A faulty switch that sticks closed can also mask a true high-pressure event — creating a compressor burnout risk.

• Specs: Opens at 395 PSI | Closes at 295 PSI | 1/8" NPT thread connection | 240 VAC rated | Sensata PS80 series (OEM: PS80-03-0018) | Cross-reference: HK02ZA395A
• OEM vs Generic: The OEM Carrier switch is factory-calibrated to exact trip and reset pressures. Generic alternatives frequently exhibit pressure drift over time, risking either false trips that interrupt cooling or missed high-pressure events that damage the compressor.
• Install difficulty: 2/5 — Requires EPA 608 certification to handle refrigerant. Recover system refrigerant before accessing the high-side port. Tools needed: manifold gauge set, adjustable wrench, Teflon tape, leak detector. Always verify pressure readings after reinstallation before recharging.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse — order by 3 PM local time for same-day dispatch.
