OEM Carrier Dual Pressure Switch Assembly HK06NB012 for Model PG92SBS48100CBAA

This OEM Dual Pressure Switch Assembly (part# HK06NB012) is the factory-specified replacement for the Carrier PG92SBS48100CBAA packaged gas unit. The pressure switch is a critical safety component that monitors inducer motor vacuum to confirm proper draft before allowing ignition. When it fails or sticks open, the furnace control board reads insufficient pressure and locks out the ignition sequence — resulting in a no-heat call with an inducer that runs but no spark or flame. A secondary LP/gas pressure switch (HK02LB008) is also included in this assembly for propane-configured units.

  • Specs: Dual pressure switch assembly | Includes HK06NB012 (inducer air pressure) + HK02LB008 (LP gas pressure switch) | SPST normally-open configuration | Rated for 92% AFUE gas packaged applications | Factory W.C. rating matched to PG92SBS48100CBAA inducer
  • OEM vs Generic: OEM switches ship with factory-calibrated setpoints, ensuring precise W.C. (water column) trip pressure. Generic aftermarket switches frequently carry ±15% tolerance on trip ratings, which can cause nuisance lockouts or — more dangerously — allow ignition under marginal draft conditions.
  • Install difficulty: 2/5 — Disconnect power and gas before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter to test continuity across switch terminals. Label and photograph all hose connections before removal. Typical replacement time: 20–30 minutes for an experienced technician.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PG92SBS48100CBAA packaged gas unit. HK06NB012 has been superseded by HK06MB012 — both are covered by this listing. Verify your existing switch's W.C. rating on the data plate or original switch body before installation. Need help confirming fitment?

Is this pressure switch compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my Carrier pressure switch?
