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 open, the control board cannot verify that the inducer is running and safe combustion airflow is established — resulting in a no-heat condition, furnace lockout, or a system that shuts down before ignition even begins.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.
