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

The Goodman 20197308 is a genuine OEM air-proving pressure switch built for the WGFM295090V5DAB modulating gas furnace. This safety control verifies proper draft/venting before the ignition sequence begins. If the inducer motor cannot pull the specified negative pressure, the switch keeps its contacts open and locks out ignition — protecting the home from unsafe combustion or blocked-vent conditions. A failed switch commonly shows as a furnace that clicks, flashes a pressure-switch fault code, and refuses to fire.

Specifications

Part number: 20197308
Set point: -.10 in. WC (water column)
Contact configuration: Normally Open (NO), closes on negative pressure
Function: Draft / vent air-proving safety switch
Fits: WGFM295090V5DAB and compatible Goodman/Amana condensing furnaces

OEM vs. Generic

The OEM Goodman switch is factory-calibrated to the exact -.10" WC trip point this furnace's control board expects. Generic switches with an approximate set point can cause false lockouts or, worse, mask a real venting problem. For a safety-critical control, always install the OEM-calibrated part.

Installation Difficulty

Rating: Easy–Moderate (2/5). Disconnect power, note or photograph the hose and wire positions, transfer the tubing and spade terminals to the new switch, and remount. About 15–20 minutes. Verify no kinks in the sensing hose and confirm proper firing on restart.

My furnace shows a pressure switch error. What do I replace?
