OEM Carrier Dual Pressure Switch Assembly HK06NB020 for Model PG96VAT60080CAAA

This OEM dual pressure switch assembly is the factory-specified replacement for the Carrier PG96VAT60080CAAA 96% AFUE gas furnace. The pressure switch monitors negative pressure generated by the inducer motor to confirm safe draft conditions before allowing ignition to proceed. When this switch fails or sticks open, the control board interprets the draft as insufficient and locks out the furnace — resulting in a no-heat call with no ignition attempt. Common symptoms include a furnace that starts the inducer but never moves to the ignition stage, or a fault code indicating a pressure switch error. This listing covers both OEM part numbers for this model: HK06NB020 (Dual Pressure Switch Assembly) and HK02LB008 (Gas Pressure Switch).

• Specs: Dual pressure switch assembly | Factory W.C. (water column) rating matched to PG96VAT60080CAAA inducer | 24V control circuit | SPST normally-open configuration
• OEM vs Generic: OEM pressure switches are calibrated to the exact W.C. rating required by this furnace. Off-spec generic switches can trigger nuisance lockouts or — worse — allow ignition under unsafe draft conditions. Always use OEM on 96% AFUE furnaces.
• Install difficulty: 3/5 — Verify power is off at the disconnect and breaker before starting. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to test switch continuity), and a manometer if verifying inducer static pressure. Check rubber hose ports for cracks or blockages before blaming the switch.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
