The pressure switch monitors negative pressure created by the inducer motor to confirm that combustion airflow is safe and sufficient before allowing the ignition sequence to proceed. When this switch fails or sticks open, the furnace will not advance past the inducer stage — resulting in a no-heat lockout condition with the inducer motor running continuously but no spark or gas delivery.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.
