Goodman 20197308 Pressure Switch (-.10" WC, Normally Open)

The Goodman 20197308 is a genuine OEM air-proving pressure switch set to -0.10 inches of water column (WC) for the Goodman/Amana AMV90905DXAB condensing gas furnace. This normally-open (NO) switch monitors inducer draft and closes only when the furnace establishes proper negative pressure, permitting the ignition sequence to proceed. It protects against operation when the flue is restricted, the trap is plugged, or the inducer is underperforming.

OEM vs. Generic

OEM Goodman switches carry the precise trip point and hysteresis this furnace's control board expects — essential for reliable, safe combustion sequencing. Because this is a safety device, we recommend OEM over generic substitutes that may differ in calibration tolerance.

Installation Difficulty

Moderate (2/5) — Connects via two spade terminals and a silicone sensing hose; confirm the tubing is clear and the correct switch position for a multi-switch furnace. Disconnect power before servicing.
