The pressure switch monitors inducer motor airflow by sensing negative pressure (draft) in the heat exchanger flue. When the inducer creates adequate draw, the switch closes to allow the control board to proceed with the ignition sequence. A failed or stuck-open pressure switch prevents the furnace or packaged unit from ever reaching ignition — the system typically locks out after 3 attempts with no spark or gas call, and the fault code will point directly to draft pressure not proved.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at \u003cstrong\u003e7\" W.C.\u003c\/strong\u003e | Closes at \u003cstrong\u003e22\" W.C.\u003c\/strong\u003e | \u003cstrong\u003e50\" wire leads\u003c\/strong\u003e | 24V control circuit | Single-port diaphragm type | Country of Origin: Mexico\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part.
