OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8JAA060090ABJA

This is the genuine OEM pressure switch assembly (with mounting bracket) for the Carrier PG8JAA060090ABJA gas furnace. The pressure switch monitors negative pressure created by the inducer draft motor to confirm safe venting conditions before allowing ignition to proceed. If the switch fails — or if it trips due to a blocked flue, cracked hose, or weak inducer — the control board locks out the ignition sequence and the furnace will not heat. Common symptoms include a blinking fault code indicating pressure switch failure, the inducer running continuously with no ignition, or the furnace cycling off before the burners light.

• Specs: 0.27" W.C. break pressure | 0.42" W.C. max make | Single-stage | Includes factory mounting bracket | OEM Part # HK06WC069
• OEM vs Generic: This is a factory-original Carrier component with tight pressure calibration tolerances. Aftermarket switches can drift out of spec, causing nuisance lockouts or — more dangerously — allowing ignition under unsafe draft conditions.
• Install Difficulty: 2/5 — Disconnect power before beginning. Tools needed: Phillips screwdriver, 1/4" nut driver, and needle-nose pliers for hose clamps. Label all hose and wire connections before removal. Inspect the rubber hose from the inducer to the switch for cracks or blockages before installing the new switch.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered by 3 PM local time.
