OEM Payne High & Low Pressure Switch for Model PA13NR06000GACAA

These OEM pressure switches — HK02ZA395 (High Pressure Switch) and HK02ZB028 (Low Pressure Switch) — are the factory-specified replacements for the Payne PA13NR06000GACAA split-system air conditioner. Pressure switches monitor refrigerant pressures on both the high and low sides of the refrigerant circuit, protecting the compressor from damage caused by abnormal operating pressures. When either switch fails or trips, the system will shut down or refuse to start entirely — commonly causing a no-cooling condition or a fault code on the control board. A failed high-pressure switch often points to restricted airflow or a refrigerant overcharge, while a failed low-pressure switch typically indicates low refrigerant charge or a restriction in the metering device.

  • Specs: HK02ZA395 — High Side Pressure Switch, OEM factory-calibrated cutout pressure | HK02ZB028 — Low Side Pressure Switch, OEM factory-calibrated cutout pressure | Designed for R-410A refrigerant systems | Direct plug-in wiring harness connector for drop-in replacement
  • OEM vs Generic: OEM pressure switches are factory-calibrated to exact cutout and reset pressures for the PA13NR06000GACAA. Generic substitutes frequently deviate from these thresholds, risking nuisance trips or — worse — insufficient compressor protection that can lead to catastrophic compressor failure.
  • Install Difficulty: 3/5 — Refrigerant system work must be performed by an EPA 608-certified technician. Tools needed: manifold gauge set, multimeter, 1/4" nut driver, and needle-nose pliers. Always recover refrigerant before replacing pressure switches on the high side. Photograph all wiring connections before disconnecting.
  • Warranty: 1-year OEM factory warranty on both HK02ZA395 and HK02ZB028. Orders placed by 3 PM local time ship same business day from our warehouse.

Compatibility: Both switches are engineered specifically for the Payne PA13NR06000GACAA R-410A split-system condenser. Verify the failed switch side (high or low) using your manifold gauges and control board fault codes before ordering. Not sure which switch you need? Our HVAC parts specialists can confirm fitment and help identify the correct part before you buy.

Frequently Asked Questions

Does this Pressure Switch fit my Payne PA13NR06000GACAA?
Yes. This is the factory-specified OEM pressure switch for the Payne PA13NR06000GACAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the pressure switch on my Payne PA13NR06000GACAA?
Difficulty: Medium (20–30 min)
Step 1: Turn off power. Step 2: Locate pressure switch near draft inducer. Step 3: Note tubing orientation. Step 4: Disconnect tubing and wires. Step 5: Remove screw, install new switch. Step 6: Reconnect tubing and wires, restore power.
My furnace shows a pressure switch error. What do I replace?
Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.
Is this pressure switch compatible with Bryant or Payne too?
Many Payne parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Payne pressure switch?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
