It confirms that the inducer draft motor is establishing adequate negative pressure before the control board allows ignition. If venting is blocked, the trap is clogged, or the inducer is weak, the switch stays open and safely prevents the furnace from firing.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 20197310\u003c\/li\u003e\n\u003cli\u003eSet Point: -0.60\" water column\u003c\/li\u003e\n\u003cli\u003eContact Configuration: Normally Open (NO)\u003c\/li\u003e\n\u003cli\u003eFunction: Draft\/vent air-proving safety switch\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMH951155DXAD and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003ePressure switches must match your furnace's exact set point and contact type.
