The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor before allowing the ignition sequence to proceed. If the switch fails to close — or is stuck open or closed — the control board will lock out the furnace, preventing any heat output. Common symptoms include a furnace that starts the inducer but never advances to ignition, a blinking fault code indicating a pressure switch error, or intermittent heating failures during cold weather.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK06WC061 | Factory-rated W.C.
