The pressure switch monitors negative pressure created by the inducer draft motor to confirm safe venting conditions before allowing ignition. When this switch fails or sticks open, the control board cannot verify proper draft, causing the furnace to lock out before ever attempting to light — leaving you with no heat. Common symptoms include a furnace that runs the inducer motor but never advances to ignition, or a fault code indicating a pressure switch error.\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 GB1AAV060155ACJA inducer specs | Single-port design | 24V control circuit compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM switch calibrated to the exact W.C. rating required by your furnace.
