The pressure switch is a normally-open safety device that monitors negative pressure created by the draft inducer motor. Once the inducer reaches proper speed and venting is confirmed, the switch closes — allowing the ignition sequence to proceed. When this switch fails or sticks open, the control board detects a fault and locks out before the igniter ever fires, leaving you with a system that runs the inducer but produces no heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.33 W.C.
