The Goodman 0130F00038 is an auxiliary (secondary) limit switch, identified by its light-blue cap, and a direct-fit replacement for the AMEC960303ANAA gas furnace and compatible Goodman/Amana models. Typically mounted near the blower compartment, this switch provides a second layer of overheat protection independent of the primary limit — shutting down the furnace if heat backs up into the blower or cabinet due to restricted airflow.
The OEM Goodman switch matches the factory trip temperature indicated by the light-blue color code, ensuring correct secondary protection. The Generic equivalent is a lower-cost, quality-matched alternative — verify the color/temperature code matches your original. Both restore backup high-limit safety.
Easy (1/5). Shut off gas and electrical power, note wire placement, remove the mounting screws, transfer the spade connectors, and install the new switch in the same location and orientation. Because color codes indicate specific trip temperatures, always match the light-blue original exactly. Repeated tripping indicates an airflow problem to be corrected, not bypassed.
Compatible with AMEC960303ANAA. Match the light-blue temperature code before ordering.
