The pressure switch monitors inducer motor operation by sensing negative air pressure inside the heat exchanger flue. When the inducer comes up to proper speed and creates adequate draft, the switch closes to allow the ignition sequence to proceed. A failed pressure switch typically causes the system to lock out before ignition — often with a diagnostic fault code indicating a failed pressure switch or open pressure switch circuit — leaving you with no heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 22 PSI Close | 7 PSI Open | 50\" wire leads | Normally open (N\/O) configuration | Factory-calibrated W.C. setpoints\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, manufactured to exact factory setpoint tolerances.
