OEM Carrier Dual Pressure Switch Assembly HK06NB021 for Model PG96VAT60100CAAA

This OEM dual pressure switch assembly is the factory-specified replacement for the Carrier PG96VAT60100CAAA 96% AFUE gas furnace. The pressure switch is a critical safety component that proves the inducer motor is operating at the correct speed and generating sufficient negative pressure before allowing the ignition sequence to proceed. When either switch fails, the control board will lock out the furnace — typically resulting in a blinking fault code, a furnace that attempts to start but never fires, or one that shuts down immediately after the inducer begins. This listing covers both OEM part numbers applicable to this model: HK06NB021 (Dual Pressure Switch Assembly) and the associated HK02LB008 (Gas Pressure Switch).

• Specs: Dual-switch assembly | Two wire terminals per switch | One hose port per switch | Factory-calibrated W.C. setpoints matched to PG96VAT60100CAAA inducer specifications
• OEM vs Generic: OEM switches are factory-calibrated to exact water column (W.C.) open/close setpoints. Aftermarket units often carry wider tolerances, risking nuisance lockouts or — more critically — failure to detect a true inducer fault, creating a flue safety hazard.
• Install difficulty: 2/5 — Label and photograph all hose and wire connections before removal. Tools needed: #2 Phillips screwdriver, needle-nose pliers, manometer (recommended for setpoint verification). Inducer must be de-energized before disconnecting hoses.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Directly fits Carrier model PG96VAT60100CAAA 96% two-stage gas furnace. Also cross-references to Bryant and Payne platforms sharing the same inducer assembly. Always verify existing switch W.C. ratings against your unit's data plate or wiring diagram before installation. Have a fitment question?
