The pressure switch monitors the negative pressure created by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or sticks open, the control board cannot verify safe draft conditions, resulting in a hard lockout — the furnace attempts to start, the inducer spins, but the burners never ignite. This part carries OEM part number \u003cstrong\u003eHK06WC061\u003c\/strong\u003e, now superseded by the current Carrier factory replacement \u003cstrong\u003eHK06MB061\u003c\/strong\u003e, which ships as the direct drop-in equivalent.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.
