OEM Payne High & Low Pressure Switch for Model PA13NR04200GAAAA

This OEM pressure switch is the factory-specified replacement for the Payne PA13NR04200GAAAA air conditioner. The pressure switch is a critical safety and proving device that monitors refrigerant pressure on both the high and low sides of the refrigerant circuit. When either switch detects pressure outside of the safe operating range — due to refrigerant loss, a blockage, or a failing compressor — it signals the control board to shut the system down, preventing costly compressor damage. Common failure symptoms include the system refusing to start, short-cycling immediately after startup, or a fault code on the control board indicating a pressure switch open condition.

  • Specs: Includes High Pressure Switch (OEM Part HK02ZA395) and Low Pressure Switch (OEM Part HK02ZB028) | Factory-calibrated trip points | Spade terminal connections | Direct OEM drop-in replacement
  • OEM vs Generic: OEM pressure switches are calibrated to exact factory trip-point specifications for the PA13NR04200GAAAA. Generic alternatives often carry wider pressure tolerances, which can allow the compressor to run outside safe operating limits or cause nuisance trips that mimic refrigerant issues.
  • Install difficulty: 3/5 — Refrigerant circuit work requires an EPA 608 certified technician. Tools needed: manifold gauge set, multimeter, screwdrivers, and spade terminal connectors. Always de-energize the unit and recover refrigerant pressure before disconnecting any pressure switch. Photograph all wiring connections before removal.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Engineered specifically for the Payne PA13NR04200GAAAA split-system air conditioner. Verify the OEM part numbers HK02ZA395 (high side) and HK02ZB028 (low side) against your unit's wiring diagram or data plate before ordering. Not sure which switch you need? Our HVAC parts team can verify fitment before you order — ships today.

Frequently Asked Questions

Does this Pressure Switch fit my Payne PA13NR04200GAAAA?
Yes. This is the factory-specified OEM pressure switch for the Payne PA13NR04200GAAAA. 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 PA13NR04200GAAAA?
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.
