The pressure switch is a critical safety device that monitors the negative pressure (draft) created by the inducer motor. Once the inducer reaches proper speed, the switch closes and signals the control board to proceed to ignition. When this switch fails, the furnace locks out before the igniter ever fires — leaving you with no heat and typically a fault code indicating a pressure switch fault or open pressure switch condition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e -0.33\" W.C.
