OEM Carrier Dual Pressure Switch Assembly HK06NB012 for Model PG95SAS30040AAAA

This OEM Dual Pressure Switch Assembly (part number HK06NB012, also cross-referenced as HK02LB008) is the factory-specified replacement for the Carrier PG95SAS30040AAAA 95% AFUE gas furnace. The pressure switch is a critical safety component that monitors the negative pressure (vacuum) created by the inducer draft motor before allowing the ignition sequence to proceed. When a pressure switch fails, the furnace will lock out before lighting — you may see a blinking error code, hear the inducer run but the burners never ignite, or experience repeated no-heat calls that reset only temporarily.

  • Specs: Dual pressure switch assembly | Two SPST switches included, each with 2 wire terminals and one hose port | Factory-calibrated W.C. (water column) set points matched to the PG95SAS30040AAAA inducer | Replaces OEM part numbers HK06NB012 and HK02LB008
  • OEM vs Generic: OEM pressure switches are factory-calibrated to exact W.C. set points for your specific model. Generic switches often carry wider tolerances that can cause nuisance lockouts in cold weather or, worse, allow unsafe flue conditions that a properly rated switch would catch.
  • Install difficulty: 3/5 — Shut off power and gas before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers, manometer (recommended to verify W.C. after install). Carefully label or photograph each hose port connection before removal — incorrect hose routing is the #1 cause of post-repair lockouts.
  • Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered for Carrier model PG95SAS30040AAAA 95% AFUE packaged gas furnace. This assembly is also compatible with a wide range of Carrier, Bryant, and Payne furnace models that share the HK06NB012 specification — verify your model number and existing hose routing before ordering. Our fitment team is available to confirm compatibility before you buy. Order today and get same-day shipping on in-stock parts.

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?

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.
