The pressure switch is a critical safety component in the inducer circuit — it monitors negative air pressure produced by the draft inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or sticks, the control board cannot verify safe flue conditions and will lock out the heating cycle entirely, leaving you with a no-heat call and a flashing fault code indicating a pressure switch error.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK06WC061 | Factory-rated W.C.
