This genuine OEM Goodman 20197308 air pressure switch is a direct-fit replacement for the Amana AMVC951155DXAE modulating variable-capacity 95% AFUE gas furnace and other compatible Goodman/Amana models. The pressure switch is a critical safety control that verifies proper venting and combustion airflow before the furnace allows ignition. A failed or drifting switch is a common cause of a furnace that won't light, short-cycles, or throws a pressure/venting fault code.
The OEM Goodman switch is factory-calibrated to the exact -0.10" WC trip point specified for this furnace, ensuring correct safety operation and preserving your equipment warranty. Lower-cost generic switches may use loose tolerances that cause nuisance lockouts or, worse, fail to trip. For a safety-critical control we recommend the genuine OEM part.
Easy (2/5). Replacement typically takes 15–20 minutes: cut power, disconnect the two spade terminals, remove the mounting screws, transfer the hose, and reverse. No special tools required. Always disconnect power at the breaker before servicing and confirm the correct hose routing.
