This switch verifies that the inducer\/draft motor is producing adequate airflow before the furnace allows ignition. If venting is blocked, the drain trap is clogged, or the inducer is weak, the switch stays open and prevents the furnace from firing — protecting against dangerous flue-gas conditions. A stuck or drifting switch is a frequent cause of no-heat lockouts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet point:\u003c\/strong\u003e -0.10\" WC (water column)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally open (closes on negative pressure)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Draft \/ air-proving pressure switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e 20197308\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman \/ Amana AMH950704CXAF furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Pressure switches are calibrated to a specific set point; the -0.10\" WC rating must match the furnace's engineered draft.
