The Goodman 0130F00038 is a genuine OEM auxiliary (secondary) limit switch, identified by its light-blue body, for Goodman and Amana gas furnaces including the AMVC961005CNAA. Mounted on the blower deck or cabinet, this auxiliary limit provides backup overtemperature protection — opening the control circuit if heat builds in the blower compartment due to restricted airflow or a stuck blower.
The color code on this switch indicates its specific trip temperature — using the correct light-blue 0130F00038 ensures the auxiliary limit trips at the exact point Goodman engineered for this furnace. Substituting a differently-rated generic switch can cause nuisance trips or inadequate protection. Match OEM color and part number for safety.
Moderate (2/5) — Disconnect power and gas. Remove the mounting screws, transfer the spade terminals, and install the replacement in the same location and orientation. Confirm the correct light-blue switch is used, then restore power and test the heating cycle.
