This normally-open (NO) switch closes on a \u003cstrong\u003e-0.10\" water-column\u003c\/strong\u003e pressure drop, proving draft during low-stage (first-stage) operation before the control board permits ignition. Because two-stage furnaces use separate switches for each firing rate, a faulty low-stage switch can cause the furnace to fail on gentle first-stage calls while still firing on high stage — an intermittent no-heat symptom that's easy to misdiagnose.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 20197308 (OEM Goodman\/Amana)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Normally Open (NO) air-proving pressure switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip point:\u003c\/strong\u003e -0.10\" WC (water column)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Low-stage \/ first-stage draft proving\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e GMV951155DXBB and compatible Goodman two-stage furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e 1\/4\" hose port, spade terminals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe low -0.10\" set point demands a precisely calibrated switch.
