OEM Carrier Dual Pressure Switch Assembly HK06NB012 for Model PG96VAT42060BCAA

This OEM dual pressure switch assembly (part number HK06NB012) is the factory-specified replacement for the Carrier PG96VAT42060BCAA 96% AFUE gas furnace. The pressure switch monitors the negative pressure produced by the inducer (draft) motor to confirm proper venting before allowing the control board to advance through the ignition sequence. A failed or out-of-spec pressure switch will cause the furnace to lock out before ignition — typically resulting in a blinking fault code, a "no heat" condition, or repeated short cycling as the board continuously retries and fails to prove the inducer.

• Specs: Dual pressure switch assembly | Factory-calibrated water column (W.C.) rating | Direct OEM replacement | Spade terminal connections | Matches factory set-point exactly for reliable inducer proving
• OEM vs Generic: This is a genuine Carrier OEM part. Factory-calibrated W.C. set-points ensure the switch opens and closes at precisely the correct pressure differential. Generic alternatives often carry wider tolerances, risking nuisance lockouts or — more dangerously — failure to detect a blocked flue condition.
• Install difficulty: 2/5 — Shut off gas and 120V power before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, manometer (recommended to verify W.C. after install). Inspect rubber hose ports for cracks and replace tubing if brittle. Photograph all hose routing before disconnecting.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.
