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

The Goodman 20197308 is a genuine OEM air-proving pressure switch engineered for the AMH951155DXAG 95% AFUE gas furnace and compatible Goodman/Amana single-stage models. This normally-open switch monitors draft-inducer vacuum and closes at a -.10 inch water column set point, confirming safe venting before the control board permits ignition. A failed or drifting switch is one of the most common causes of no-heat calls, short-cycling, and ignition lockout.

Specifications

OEM Part Number: 20197308
Type: Air-proving / draft pressure switch
Contact configuration: Normally Open (NO)
Set point: -.10" WC (water column)
Fits: AMH951155DXAG and compatible Goodman/Amana furnaces
Single-port design with 1/4" spade terminals

OEM vs. Generic

Our OEM 20197308 is calibrated to the exact factory set point, guaranteeing reliable proving and full furnace warranty compliance. Generic universal switches often carry a slightly different trip pressure, which can cause nuisance lockouts or fail to prove on high-static installations. For a safety-critical component, OEM is the recommended choice.

Installation Difficulty: Easy (2/5)

Replacement takes most homeowners and technicians 15–20 minutes with basic hand tools. Cut power at the breaker, photograph the tubing and wiring, transfer the vacuum hose and spade connectors to the new switch, and mount it in the original bracket. Always verify draft and combustion after service.
