OEM Payne High & Low Pressure Switch Kit for Model PA13PR060000ACAA

This OEM-matched pressure switch kit includes both the high pressure switch (HK02ZA395) and low pressure switch (HK02ZB028) factory-specified for the Payne PA13PR060000ACAA packaged air conditioner. Pressure switches are safety devices that monitor refrigerant-side pressures to protect the compressor from operating under dangerous high- or low-pressure conditions. When either switch fails or trips, the system will lock out — typically displaying a fault code and refusing to start the cooling cycle until the fault is cleared or the faulty switch is replaced.

• Specs: Includes HK02ZA395 High Pressure Switch and HK02ZB028 Low Pressure Switch | Factory-calibrated trip points | SPST normally-closed configuration | Designed for R-410A refrigerant systems | OEM-matched wiring terminals for direct plug-in replacement
• OEM vs Generic: OEM pressure switches are calibrated to exact factory trip points for the PA13PR060000ACAA refrigerant circuit. Generic substitutes frequently use wider pressure tolerances, risking nuisance trips or — more dangerously — failure to protect the compressor under true fault conditions.
• Install difficulty: 3/5 — Refrigerant-side pressure switches require proper recovery and handling of R-410A refrigerant per EPA Section 608 regulations. Tools needed: refrigerant manifold gauges, recovery machine, adjustable wrench, multimeter. Always verify system pressures after replacement. A licensed HVAC technician is recommended for this repair.
• Warranty: 1-year OEM factory warranty on both switches. Orders placed by 3 PM local time ship same business day from our warehouse.

Compatibility: This kit is engineered specifically for the Payne PA13PR060000ACAA 5-ton packaged air conditioning unit. Always verify OEM part numbers HK02ZA395 and HK02ZB028 against your unit's wiring diagram and data plate before ordering.
