The Goodman 0130F00436 Pressure Switch is the genuine OEM negative-air-pressure safety switch for the AMVC960803BNAA two-stage 96% AFUE gas furnace and compatible Goodman/Amana models. It proves that the inducer draft motor is running and that the vent is clear before allowing ignition. A failed or drifted switch is the most common cause of a furnace that clicks but won't light, or that locks out on a pressure-switch fault code.
Pressure switches are calibrated to a precise W.C. setpoint tuned to this furnace's inducer and venting. The OEM 0130F00436 guarantees the correct trip pressure and hose-port configuration. A mismatched generic switch can prevent ignition entirely or fail to detect a blocked flue — a safety concern. OEM is the recommended choice.
Moderate (2/5). One or two mounting screws, a silicone hose port, and spade connectors. Note hose routing before removal. Roughly 15–20 minutes. Shut off gas and power first.
