OEM Carrier Dual Pressure Switch Assembly for Model PG96VAT42060BAAA

This OEM dual pressure switch assembly is the factory-specified replacement for the Carrier PG96VAT42060BAAA 96% AFUE two-stage gas furnace. The pressure switch monitors negative pressure created by the inducer draft motor to confirm safe venting conditions before allowing the ignition sequence to proceed. When either switch fails — or when a flue restriction causes it to stay open — the furnace control board will lock out and no heat will be produced. Common failure symptoms include a furnace that starts the inducer but never advances to ignition, a blinking fault code indicating a pressure switch fault, or a furnace that short-cycles on cold startup.

• Specs: Dual pressure switch assembly | OEM part numbers HK06NB012 (assembly) and HK02LB008 (gas pressure switch) | Factory-calibrated W.C. (water column) rating | Designed for two-stage 96% AFUE inducer systems
• OEM vs Generic: OEM switches are factory-calibrated to the exact W.C. trip point for this furnace. Generic alternatives often carry wider tolerances, which can cause nuisance lockouts or, worse, allow ignition under marginal venting conditions — a safety risk on sealed-combustion furnaces.
• Install Difficulty: 3/5 — Always disconnect power and gas before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, manometer (to verify W.C. on reinstall), and needle-nose pliers for hose clamps. Photograph all tubing connections before removal. Inspect inducer hoses and drain lines for blockages before condemning the switch.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PG96VAT42060BAAA packaged gas furnace. Cross-references OEM part numbers HK06NB012 and HK02LB008. Verify your existing switch's W.C. rating and hose port configuration against your unit's wiring diagram before installing.
