OEM Payne High & Low Pressure Switch for Model PA13NR03000GAAAA

This OEM pressure switch is the factory-specified replacement for the Payne PA13NR03000GAAAA air conditioner. The pressure switch monitors refrigerant pressure levels in the system — the high-pressure switch (OEM part HK02ZA395) protects against dangerously elevated refrigerant pressure, while the low-pressure switch (OEM part HK02ZB028) guards against abnormally low pressure conditions such as refrigerant loss or a blocked metering device. When either switch fails or trips, the system will lock out and refuse to operate, protecting the compressor from catastrophic damage. Common symptoms include the unit failing to start, short-cycling, or triggering a fault code on the control board related to pressure faults.

  • Specs: High Pressure Switch — OEM Part HK02ZA395 | Low Pressure Switch — OEM Part HK02ZB028 | Factory-calibrated setpoints | Rated for R-410A refrigerant systems | Direct plug-in connector
  • OEM vs Generic: OEM pressure switches are calibrated to exact factory trip and reset thresholds. Generic aftermarket switches frequently carry wider tolerances, risking nuisance trips or — more dangerously — failing to protect the compressor at the correct pressure threshold.
  • Install difficulty: 3/5 — Refrigerant system work must be performed by an EPA 608-certified technician. Tools needed: manifold gauge set, flathead screwdriver, needle-nose pliers, multimeter. Always recover refrigerant before disconnecting a pressure switch on a live system. Photograph wiring connections before removal.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders ship same business day from our warehouse when placed before 3 PM local time.

Compatibility: Engineered as a direct OEM replacement for the Payne PA13NR03000GAAAA split-system air conditioner. Verify your failed switch by matching the OEM part number (HK02ZA395 for high-pressure, HK02ZB028 for low-pressure) printed on the original component before ordering. Not sure which switch you need? Our HVAC parts specialists confirm fitment before every order — reach out before you buy.

Frequently Asked Questions

Does this Pressure Switch fit my Payne PA13NR03000GAAAA?
Yes. This is the factory-specified OEM pressure switch for the Payne PA13NR03000GAAAA. 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 PA13NR03000GAAAA?
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?
