The pressure switch is a critical safety component in the furnace's ignition sequence — it monitors negative pressure created by the inducer draft motor to confirm that proper venting is established before allowing the gas valve to open. When this switch fails or sticks, the control board cannot verify safe draft conditions, resulting in a no-heat lockout, a flashing fault code, or the system shutting down immediately before ignition begins.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Factory-rated W.C.
