OEM Carrier Dual Pressure Switch Assembly HK06NB012 for Model PG92SCS48100CAAA

This OEM dual pressure switch assembly (part number HK06NB012) is the factory-specified replacement for the Carrier PG92SCS48100CAAA 92% AFUE gas furnace. The pressure switch is a critical safety component that monitors the negative pressure (vacuum) created by the inducer draft motor to confirm safe flue venting conditions before allowing ignition to proceed. A failed pressure switch causes a hard lockout before ignition — the inducer will run, but the furnace will never reach the ignition stage, resulting in a no-heat call. Secondary part number HK02LB008 (Gas Pressure Switch) is also covered by this assembly listing for LP/propane-configured units.

  • Part Numbers: HK06NB012 (Dual Pressure Switch Assembly) | HK02LB008 (Gas/LP Pressure Switch) | Direct replacement: HK06MB012
  • OEM vs Generic: OEM switches are factory-calibrated to exact water column (W.C.) setpoints for the PG92SCS48100CAAA. Generic alternatives risk nuisance lockouts or — more dangerously — allowing operation under unsafe flue conditions due to W.C. tolerance drift.
  • Install Difficulty: 3/5 — Inducer must be confirmed non-running before servicing. Tools needed: multimeter (continuity test), 1/4" nut driver, needle-nose pliers, manometer (recommended for W.C. verification). Always check hose and port connections for cracks during replacement.
  • Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Engineered to fit the Carrier PG92SCS48100CAAA 92% efficient packaged gas furnace series. Verify the W.C. rating on your existing switch before ordering. Our parts specialists are available to confirm fitment — contact us before you order if you have any questions.
