As a normally-open draft-proving switch with a -0.10\" WC setpoint, it confirms adequate inducer draft on the low-fire \/ low-pressure stage before the control board permits ignition. In a two-stage condensing furnace, multiple pressure switches monitor different draft thresholds — this lower-setpoint switch guards the first-stage firing rate.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20197308\u003c\/li\u003e\n\u003cli\u003eSetpoint: -0.10\" WC (water column)\u003c\/li\u003e\n\u003cli\u003eContact Type: Normally Open (NO), single-pole\u003c\/li\u003e\n\u003cli\u003eFunction: Low-stage draft \/ air-proving safety switch\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Amana-compatible)\u003c\/li\u003e\n\u003cli\u003eFits: AMVC950905DXBA and related 2-stage models\u003c\/li\u003e\n\u003cli\u003eCategory: Pressure Switch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis switch trips at a precise -0.10\" WC to match the furnace's low-fire draft. Substituting a switch with a different setpoint can cause the burner to skip stages, short-cycle, or ignite without proper draft.
