OEM Carrier Pressure Switch Assembly w/Bracket (HK06WC069) for Model PG8MAA036045ABJA

This OEM pressure switch assembly with bracket is the factory-specified replacement part for the Carrier PG8MAA036045ABJA packaged gas furnace. The pressure switch monitors negative pressure created by the inducer draft motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or sticks, the furnace will lock out before the burners ever light — a common symptom being a draft motor that runs but is immediately followed by a fault code indicating a pressure switch failure.

• Specs: OEM Part Number HK06WC069 | Pressure Switch Assembly with Mounting Bracket | Factory-calibrated W.C. (water column) rating | Direct drop-in replacement — no modification required
• OEM vs Generic: This is a genuine OEM Carrier component manufactured to exact factory W.C. tolerances. Aftermarket pressure switches frequently carry wider set-point tolerances, which can cause nuisance lockouts or, worse, unsafe ignition attempts under marginal draft conditions.
• Install Difficulty: 2/5 — Disconnect power before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a manometer (recommended to verify set-point after install). Always inspect the rubber hose connections for cracks or blockages before replacing the switch itself.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8MAA036045ABJA packaged gas unit.
