The Goodman 20197312 Pressure Switch is a genuine OEM draft-proving control for the GMH950905DXAA 95% AFUE two-stage furnace and compatible Goodman/Amana models. This normally-open switch monitors inducer draft and closes at a -0.37" water column setpoint, confirming proper venting and combustion airflow before the ignition sequence is allowed to proceed — a critical safety interlock against blocked vents or a failing inducer.

Specifications

OEM Part Number: 20197312
Setpoint: -0.37" WC (water column)
Action: Normally Open (NO), closes on draft
Function: Inducer / draft-proving pressure switch
Compatible Model: GMH950905DXAA and related Goodman/Amana furnaces
Equipment: High-Efficiency Gas Furnace

OEM vs. Generic

Pressure-switch calibration is safety-critical. This factory-original Goodman switch is set precisely to -0.37" WC with the correct port and bracket. Generic switches with even slightly off setpoints cause intermittent ignition lockouts or, worse, defeat the venting safety check. OEM is strongly recommended.

Installation Difficulty

Easy — one mounting bracket, a single tubing connection, and two spade terminals. Disconnect power first and confirm the hose is free of condensate before restarting.
