The pressure switch monitors negative pressure created by the 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 draft conditions — resulting in a \u003cstrong\u003efurnace lockout before ignition\u003c\/strong\u003e, a blinking fault code, or a system that attempts to start and immediately shuts down.
