The pressure switch monitors inducer draft pressure to confirm the heat exchanger is properly venting before allowing ignition. When this switch fails, the control board receives no confirmation signal and the system locks out — resulting in a no-heat condition, a flashing fault code, or a system that runs the inducer motor continuously without progressing to the ignition stage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Closes at 22\" W.C. | Opens at 7\" W.C. | 50\" wire leads | Single-port design | Factory-calibrated setpoints\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM switch ships with exact factory-calibrated trip points (±0.1\" W.C.).
