OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8JAA042090ABJA

This is the genuine OEM Carrier Pressure Switch Assembly with Bracket, part number HK06WC069, factory-specified for the Carrier PG8JAA042090ABJA gas furnace. The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor before allowing the ignition sequence to proceed. When the inducer motor runs and generates the correct pressure differential, the switch closes and signals the control board to advance through the ignition stages. A failed pressure switch will cause the furnace to lock out prior to ignition — often with a diagnostic fault code — leaving your home without heat.

• Part Number: HK06WC069 | Pressure Switch Assembly with Mounting Bracket | Single-stage draft-proving switch | Rated: -0.27" W.C. break / -0.42" W.C. max make
• OEM vs Generic: This OEM switch is factory-calibrated to the exact water column rating required by the Carrier PG8JAA042090ABJA. Generic aftermarket switches frequently carry wider pressure tolerances, risking nuisance lockouts or — worse — unsafe ignition under insufficient draft conditions.
• Install Difficulty: 2/5 — Power down the furnace and allow it to cool before beginning. Tools needed: 1/4" nut driver, needle-nose pliers, and a smartphone to photograph the existing wiring harness and hose routing before removal. The included bracket simplifies direct bolt-in replacement.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. Ships same business day from our warehouse when ordered by 3 PM local time. Free ground shipping on orders over $99.

Compatibility: Engineered for the Carrier PG8JAA042090ABJA gas furnace. This part is also cross-referenced for select Bryant and Payne furnace models sharing the same inducer and pressure specification — confirm your unit's existing switch W.C. rating and bracket configuration before ordering. Our HVAC parts specialists are available to verify fitment prior to purchase.
