Goodman 20197308 Furnace Pressure Switch

The Goodman 20197308 is a genuine OEM negative-air pressure switch engineered for the Amana AMV91155DXBB variable-speed gas furnace and compatible Goodman/Amana 90%+ AFUE models. This normally-open switch monitors combustion draft and confirms proper venting before the control board allows ignition, protecting your home from unsafe operation.

Specifications

Actuation setpoint: -.10 in. water column (WC)
Switch state: Normally Open (N.O.)
Function: Draft / vacuum proving safety switch
Fits: Amana AMV91155DXBB and select Goodman/Amana furnaces
Connection: Single hose port with spade terminals

OEM vs. Generic

This is the genuine OEM Goodman component, calibrated to the exact -.10 in. WC trip point the furnace control expects. Generic replacements often drift out of spec, causing nuisance lockouts or unsafe ignition. For a safety-critical draft switch, we strongly recommend OEM.

Common Symptoms

Furnace ignites then shuts off on lockout
Inducer runs but burners never light
Pressure switch fault codes on the control board

Installation Difficulty: Easy (1/5)

Replacement is a straightforward DIY job: power off the furnace, disconnect the hose and two wire terminals, unscrew the switch, and reinstall the new unit in the same orientation. Always verify the tubing is clear of condensate before restoring power. If you are unsure, consult a licensed HVAC technician.

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