OEM Carrier Dual Pressure Switch Assembly HK06NB020 for Model PG92SAS60080CAAA

This OEM dual pressure switch assembly is the factory-specified replacement for the Carrier PG92SAS60080CAAA 92% AFUE gas furnace. The pressure switch monitors negative air pressure created by the inducer motor to confirm safe venting conditions before allowing the ignition sequence to proceed. When this switch fails or sticks, the control board cannot verify proper draft, triggering a safety lockout — typically indicated by a fault code before the burners ever fire. A faulty pressure switch is one of the most common causes of a furnace that starts the inducer but never lights. This listing covers both the HK06NB020 Dual Pressure Switch Assembly and the companion HK02LB008 Gas Pressure Switch, giving you the complete OEM switch set for this model.

• Specs: OEM Part Numbers: HK06NB020 (Dual Pressure Switch Assembly) & HK02LB008 (Gas Pressure Switch) | Carrier Factory Authorized Parts | Matches original W.C. (water column) rating for PG92SAS60080CAAA | 24V control circuit compatible
• OEM vs Generic: OEM pressure switches are factory-calibrated to the exact water column rating for this model. Off-spec generic switches can trip too early or too late, causing intermittent lockouts or — more dangerously — allowing ignition under improper draft conditions.
• Install difficulty: 3/5 — Shut off gas and power before starting. Tools needed: 1/4" nut driver, flathead screwdriver, digital manometer (recommended), and a multimeter to test switch continuity. Inspect inducer tubing and port for blockages before replacing the switch. Photograph all hose and wiring connections before removal.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.
