The pressure switch proves that the inducer motor has established a proper negative pressure draft before the control board advances to ignition. When it fails or sticks open, the furnace will lock out entirely — often before a single ignition attempt — leaving you with a no-heat call and a flashing diagnostic code indicating a pressure switch fault.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.
