Goodman 20197308 Pressure Switch (-.10 in. WC, NO)

The Goodman 20197308 is a genuine OEM normally-open (NO) negative-pressure switch calibrated to a -.10 in. WC set point for the WGFM295070V4CAB gas furnace and compatible Goodman/Amana models. It confirms proper induced-draft airflow — often on the condensate/secondary drain circuit — before the control board permits ignition. When the blower pulls the specified vacuum, the contacts close and the furnace is allowed to proceed.

Specifications

Type: Single negative-pressure switch, normally open
Trip point: -.10 in. WC
Application: High-efficiency induced-draft gas furnaces
Fit: WGFM295070V4CAB and cross-compatible Goodman/Amana units
Connections: 1/4 in. spade terminals with hose port

OEM vs. Generic

The OEM switch is factory-set to Goodman's exact -.10 in. WC trip pressure, preventing the nuisance lockouts and false safety trips common with approximate aftermarket switches. Because this component gates ignition for safety, exact calibration matters — OEM is the dependable option.

Installation Difficulty

Moderate — Approximately 15–25 minutes. Disconnect furnace power, transfer the wire terminals, and reseat the pressure hose on the correct port. Confirm the switch closes on a call for heat and that no fault codes remain. HVAC technician recommended.

Disconnect power and gas before servicing. Verify tubing is clear of condensate blockage.
