OEM Carrier Pressure Switch Assembly w/Bracket HK06WC069 for Model PG8JAA048090ADJA

This OEM pressure switch assembly with bracket (part# HK06WC069) is the factory-specified replacement for Carrier model PG8JAA048090ADJA gas furnaces. The pressure switch is a critical safety component that monitors negative pressure produced by the inducer (draft) motor. Before each ignition cycle, the furnace control board checks that the inducer is running and has established proper airflow — the pressure switch closes to confirm this. When the switch fails or sticks open, the board locks out the ignition sequence entirely, leaving you with no heat and often a diagnostic fault code indicating a pressure switch fault.

• Specs: Single-stage draft-sensing pressure switch | Includes factory bracket for direct bolt-in installation | Factory-calibrated W.C. (water column) set point | Honeywell IS20205-4021 internals | Fits Carrier PG8JAA048090ADJA packaged gas furnace
• OEM vs Generic: This is a genuine Carrier OEM part — factory-matched water column rating and hose port diameter. Aftermarket switches often ship with incorrect W.C. ratings that cause nuisance lockouts or, worse, allow the furnace to run with insufficient combustion airflow. Don't risk it on a safety switch.
• Install Difficulty: 2/5 — Straightforward swap once the furnace is powered down. Tools needed: 1/4" nut driver or 5/16" nut driver, flat-head screwdriver, and a manometer (recommended to verify set point after install). Always check the rubber hose and port for cracks or blockage before replacing the switch — a clogged hose is the #1 misdiagnosed pressure switch failure.
• Warranty: 1-year OEM factory warranty. New-in-box genuine part. Ships same business day from our warehouse.
