The Goodman 20197308 Pressure Switch is a genuine OEM air-proving safety switch rated at -0.10" WC, normally open (NO), engineered for the AMV90905DXBB high-efficiency gas furnace and compatible Goodman/Amana models. On multi-stage condensing furnaces this low-pressure switch proves draft during low-fire operation, confirming the inducer has established the correct airflow before the control board allows ignition on the low stage.
Because this switch trips at a very sensitive -0.10" WC, calibration accuracy matters. The OEM 20197308 is factory-set to Goodman's exact specification, while generic equivalents often differ enough to cause low-stage lockouts, failure to reach high fire, or intermittent no-heat calls. Choose the genuine part for dependable staging and safe operation.
Rating: Easy to Moderate. Disconnect power, note the wire terminals and the sensing hose routing (label them if needed), and swap the switch on its bracket. Confirm the sensing port and tubing are clear of condensate before reconnecting. Estimated time: 15–25 minutes, followed by a full heat-cycle test through both stages.
Restore correct low-fire staging on your AMV90905DXBB with the exact pressure switch it requires.
