OEM Payne High & Low Pressure Switch Kit for Model PA10EA06000GACAA

This OEM pressure switch kit contains both the high pressure switch (HK02ZA395) and low pressure switch (HK02ZB028) factory-specified for the Payne PA10EA06000GACAA packaged unit. Pressure switches monitor the inducer motor's draft pressure to confirm safe venting conditions before allowing the ignition sequence to proceed. When either switch fails — or when they stick open due to a faulty inducer, blocked flue, or diaphragm wear — the control board will lock out the heat cycle entirely, leaving you with a no-heat call and a fault code pointing to inducer or pressure circuit failure.

  • Specs: Includes OEM High Pressure Switch (HK02ZA395) and Low Pressure Switch (HK02ZB028) | Factory-calibrated W.C. (water column) ratings matched to PA10EA06000GACAA inducer performance | SPST normally-open contacts | Direct OEM replacement — no modification required
  • OEM vs Generic: OEM pressure switches are calibrated to the exact W.C. trip point required by the Payne PA10EA06000GACAA. Generic substitutes often carry loose tolerances that can cause nuisance lockouts or, worse, fail to detect true venting failures — a safety risk not worth taking.
  • Install difficulty: 3/5 — Shut off power and gas before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, manometer (recommended to verify W.C. after install), and a multimeter to confirm switch continuity. Photograph hose and wiring routing before removal. The inducer assembly may need to be partially accessed depending on cabinet configuration.
  • Warranty: 1-year OEM factory warranty. Orders placed by 3 PM local time ship same business day from our climate-controlled warehouse.

Compatibility: This kit is engineered specifically for the Payne PA10EA06000GACAA packaged gas/electric unit. Always cross-reference both OEM part numbers — HK02ZA395 and HK02ZB028 — against your unit's wiring diagram and data plate before installation. If you are unsure which switch has failed, our technical team can help you diagnose using your fault code and multimeter readings before you order.

Frequently Asked Questions

Does this Pressure Switch fit my Payne PA10EA06000GACAA?
Yes. This is the factory-specified OEM pressure switch for the Payne PA10EA06000GACAA. 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 PA10EA06000GACAA?
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?
