OEM Carrier Dual Pressure Switch Assembly HK06NB028 for Model PG92SCS60120DAAA

This OEM dual pressure switch assembly is the factory-specified replacement for the Carrier PG92SCS60120DAAA 92% AFUE packaged gas furnace. The pressure switch monitors negative pressure (draft) created by the inducer motor to verify safe flue gas venting before allowing the ignition sequence to proceed. When this switch fails — or becomes stuck open or closed — the furnace control board detects an unsafe condition and initiates a lockout, resulting in a no-heat call with a pressure switch fault code. Common symptoms include: the inducer runs but ignition never starts, repeated short-cycling with a fault flash code, or a furnace that runs briefly then shuts down before the burners ignite.

• OEM Part Numbers: HK06NB028 (Dual Pressure Switch Assembly) | HK02LB008 (Gas Pressure Switch) — both superseded by current production part HK06MB028. Factory-authorized replacement, exact form and fit.
• OEM vs Generic: OEM pressure switches are factory-calibrated to precise W.C. (water column) setpoints. Off-brand switches often carry wider tolerances that cause nuisance trips or — worse — fail to detect true inducer faults, creating a potential safety hazard. OEM is the only choice for a safety-critical component like this.
• Install difficulty: 3/5 — Shut off gas and 24V power before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, manometer or digital magnehelic gauge (to verify setpoint after install), and camera/phone for pre-removal wiring photos. Tubing orientation is critical — confirm port labeling matches original routing.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before 3 PM local time.
