OEM Carrier Dual Pressure Switch Assembly HK06NB021 for Model PG96VAT60100CDAA

This is the OEM factory-specified dual pressure switch assembly (part number HK06NB021, superseded by HK06MB021) for the Carrier PG96VAT60100CDAA 96% AFUE gas furnace. The pressure switch is a critical safety component that monitors the negative pressure (vacuum) created by the inducer motor to confirm proper draft before allowing ignition. When it fails or sticks open, the furnace will lock out before the ignition sequence begins — leaving you with no heat and a flashing fault code on the control board.

  • Specs: Dual pressure switch assembly | Two independent switches included | Each switch features 2 wire terminals and 1 hose port | Factory-calibrated W.C. (water column) trip points matched to the PG96VAT60100CDAA inducer and heat exchanger
  • OEM vs Generic: OEM pressure switches are calibrated to exact factory W.C. specifications. Aftermarket units often carry wider tolerances, which can cause nuisance lockouts or — more dangerously — allow ignition under marginal draft conditions. For a safety-critical component like this, OEM is strongly recommended.
  • Install Difficulty: 2/5 — Power down and lockout the furnace before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Photograph all hose and wire connections before removal. Inspect inducer hoses for cracks while you have the panel open — a leaking hose is a common root cause of pressure switch failure.
  • Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed as a direct OEM replacement for the Carrier PG96VAT60100CDAA high-efficiency gas furnace. Also compatible with select Bryant and Payne models sharing the same inducer assembly. Always verify your existing switch's W.C. rating against the data label on your unit before installing.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG96VAT60100CDAA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG96VAT60100CDAA. 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 Carrier PG96VAT60100CDAA?
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 Carrier 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 Carrier 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?
