OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8MAA036110ABJA

This OEM pressure switch assembly (with bracket) is the factory-specified replacement for the Carrier PG8MAA036110ABJA gas furnace. The pressure switch monitors negative pressure created by the inducer motor to confirm proper venting and draft before allowing the ignition sequence to proceed. When it fails or sticks open, the control board will lock out the furnace before a single spark fires — leaving you with a no-heat call and a flashing fault code. Common symptoms include: furnace starts inducer but never advances to ignition, a pressure switch fault code on the control board, or the furnace short-cycling through repeated inducer attempts.

• OEM Part Number: HK06WC069 | Factory-original Carrier Pressure Switch Assembly with pre-attached mounting bracket — no bracket fabrication required
• OEM vs Generic: OEM switches are calibrated to the exact water column (W.C.) setpoint specified for this furnace. Generic aftermarket switches frequently carry wider tolerances, which can cause nuisance lockouts or — more dangerously — allow the furnace to fire under insufficient draft conditions.
• Install Difficulty: 2/5 — Straightforward swap in the blower compartment. Tools needed: 1/4" nut driver, flathead screwdriver, and needle-nose pliers for hose clamps. Always disconnect power at the disconnect switch before starting. Photograph all hose and wire connections before removal.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
