The pressure switch is a critical safety device that monitors negative air pressure generated by the inducer motor, confirming proper draft before allowing the control board to proceed with ignition. When this switch fails, the furnace will typically lock out before the ignition sequence begins — you may notice the inducer motor running continuously while the burners never light, or a fault code indicating an open pressure switch on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number HK06WC090 | Includes factory mounting bracket | Rated for the specific water column (W.C.) pressure of the GB1AAV024035AAJA inducer assembly | Single-port configuration factory-matched to this model\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to the exact W.C. threshold required by Carrier engineering.
