OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8MAA024070ABJA

This is the genuine OEM Pressure Switch Assembly with Bracket for the Carrier PG8MAA024070ABJA gas furnace. The pressure switch is a critical safety component that monitors the negative pressure (vacuum) created by the draft inducer motor before allowing the ignition sequence to proceed. If the inducer fails to generate adequate airflow — or if the switch itself fails — the control board receives no proof signal and locks out the furnace entirely, resulting in a no-heat condition. Common symptoms of a failed HK06WC069 include the furnace shutting down before ignition, a blinking fault code indicating a pressure switch fault, or the inducer running continuously without the burners lighting.

• Specs: Part Number HK06WC069 | Honeywell IS20205-4021 | Set Point: .27" W.C. break / .42" W.C. max make | Single-stage | Includes mounting bracket | Factory-spec hose port and terminal configuration
• OEM vs Generic: This is a genuine Carrier OEM assembly — not an aftermarket substitute. OEM switches are calibrated to exact W.C. set points from the factory. Generic alternatives can drift outside specification, causing nuisance lockouts or — more dangerously — failing to detect a true blocked flue condition.
• Install Difficulty: 2/5 — The bracket simplifies swap-out. Power off the furnace and allow the inducer to cool. Disconnect the rubber hose and two wiring terminals, unbolt the old bracket, and mount the new assembly in its place. Tools needed: 1/4" nut driver, needle-nose pliers. Always inspect the hose for cracks or blockages before reinstalling.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
