The Goodman 0130F00439 Pressure Switch is a genuine OEM safety component designed for Amana AMES960803BNAA 96% AFUE two-stage gas furnaces and compatible Goodman/Amana models. This air-proving switch monitors inducer draft and verifies proper venting airflow before the furnace allows ignition, protecting your home from unsafe combustion conditions.
When a pressure switch fails, the furnace typically locks out, short-cycles, or throws a pressure-switch fault code and refuses to fire. Replacing it with the correct OEM switch restores safe, reliable heating.
The OEM Goodman 0130F00439 is factory-calibrated to the exact -1.27" WC trip point your furnace's control board expects, ensuring correct sequencing and safety compliance. Generic universal switches may have slightly different set points or hose barb geometry, risking nuisance lockouts. For a safety-critical component, OEM is strongly recommended.
Easy (DIY-friendly, 15–20 minutes). Requires disconnecting power, transferring the sensing hose and two spade terminals, and mounting with the existing screws. Always shut off gas and power before servicing.
