The Goodman 20197308 Pressure Switch is a genuine OEM draft-safety control for the WGFM295045V3BAB gas furnace and compatible Goodman/Amana equipment. This normally open switch senses negative pressure from the induced-draft blower and closes at -0.10 in. WC to confirm safe venting before the ignition sequence begins. It guards against blocked flue conditions, condensate backups, and inducer failures that would otherwise allow unsafe combustion.

Setpoint: -0.10 in. WC
Configuration: Normally open (NO), closes on pressure rise
Function: Draft / inducer airflow proving switch
Fit: WGFM295045V3BAB and compatible Goodman/Amana furnaces

OEM vs. Generic: The 20197308 arrives factory-calibrated to the exact -0.10" setpoint your control board expects, with the correct port and terminal layout. Aftermarket switches with approximate calibration are a common source of intermittent no-heat lockouts on cold mornings. For a reliable safety circuit, install the genuine OEM part.

Install difficulty: Moderate (2/5). Expect about 20 minutes with a nut driver: shut off power and gas, photograph the hose and wire routing, transfer the tubing and spade terminals to the new switch, and remount it. After restart, confirm the burners light on the first call for heat. If you have a manometer, verify the switch closes at the rated pressure; otherwise a licensed technician can confirm. Always de-energize the furnace at the breaker first.

Backed by genuine Goodman quality and shipped from National HVAC Parts.
