The pressure switch monitors negative pressure created by the inducer motor during the pre-purge cycle. If adequate draft is not proven, the switch prevents the ignition sequence from proceeding — protecting the system from unsafe operation. A failed pressure switch typically causes the furnace to lockout before ignition, often with a diagnostic fault code indicating a pressure switch error. You may also observe the inducer motor running continuously while the burners never light.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.
