OEM Carrier Dual Pressure Switch Assembly HK06NB021 for Model PG92SAS60100CAAA

This OEM Dual Pressure Switch Assembly is the factory-specified replacement for the Carrier PG92SAS60100CAAA gas furnace. The pressure switch is a critical safety component that proves your inducer (draft) motor is operating at the correct RPM and generating adequate negative pressure before allowing the ignition sequence to proceed. When this switch fails, the furnace control board will lock out the heating cycle entirely — typically before the igniter even energizes. Common symptoms include a furnace that starts the inducer motor, then shuts down with no ignition attempt, or a fault code indicating a pressure switch fault on the control board display.

• OEM Part Numbers: Primary — HK06NB021 (Dual Pressure Switch Assembly) | Secondary — HK02LB008 (Gas Pressure Switch). Both are covered by this listing. Current OEM supersession: HK06MB021.
• OEM vs Generic: OEM Carrier pressure switches are factory-calibrated to exact water-column (W.C.) setpoints for the PG92SAS60100CAAA's inducer and heat exchanger. Aftermarket switches with loose W.C. tolerances can cause nuisance lockouts or — more dangerously — fail to detect a blocked flue condition.
• Install Difficulty: 3/5 — Shut off gas and power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a manometer or magnehelic gauge to verify W.C. setpoint after installation. Photograph all hose and wiring connections before removal. Inspect inducer hose for cracks or blockages before installing the new switch — a deteriorated hose causes the same symptoms as a failed switch.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed for the Carrier PG92SAS60100CAAA 92% AFUE packaged gas furnace. Also cross-references to Bryant and Payne equivalent models. Always verify your existing switch's W.C. rating from the data label on the switch body before ordering — this ensures correct setpoint match. Questions about fitment?
