OEM Carrier Pressure Switch with Bracket HK06WC090 for Model GB1AAV060111AEJA

This is the factory OEM replacement pressure switch with integrated mounting bracket for the Carrier GB1AAV060111AEJA gas furnace. The pressure switch is a safety device that monitors negative air pressure created by the inducer draft motor before allowing the ignition sequence to proceed. When the switch fails — or the hose, port, or inducer is compromised — the control board cannot confirm proper venting, and the furnace will lock out before ignition, often displaying a fault code related to pressure switch failure. Common symptoms include a furnace that runs the inducer but never advances to ignition, repeated short-cycling, or a blinking LED fault code indicating an open pressure switch circuit.

• Specs: OEM Part Number HK06WC090 | Includes factory mounting bracket | Rated water column (W.C.) matched to Carrier GB1AAV060111AEJA specifications | Single-port design | 24V control circuit compatible
• OEM vs Generic: This OEM switch is calibrated to the exact W.C. rating required by your furnace. Generic alternatives often carry wider pressure tolerances, risking nuisance lockouts or — more critically — failure to detect a true venting fault, which poses a carbon monoxide hazard.
• Install Difficulty: 2/5 — Disconnect power and gas before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a manometer if verifying W.C. after installation. Inspect the rubber hose and drain port for blockages before replacing the switch, as a clogged hose is often the root cause of switch failure.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.
