The pressure switch monitors the inducer motor's draft pressure to confirm proper airflow before allowing ignition. When this switch fails or sticks open, the control board cannot verify safe venting conditions — resulting in a no-heat lockout, repeated ignition attempts with no flame, or an error code pointing to the inducer circuit. This is one of the most common furnace service calls and a straightforward OEM swap.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 22 PSI Close \/ 7 PSI Open | 50\" wire leads | Low-pressure draft sensing | Factory-calibrated set points\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM switch calibrated to exact factory set points.
