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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM switch is calibrated to the exact W.C. rating required by your furnace.

Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a manometer if verifying W.C. after installation.
