The Goodman 0130F00038 Auxiliary Limit Switch (Light Blue) is a genuine OEM secondary safety control for the Goodman/Amana ADVC80905CXAA gas furnace. This auxiliary limit adds a backup layer of overtemperature protection — typically guarding the blower compartment or a secondary zone of the heat exchanger — and de-energizes the burners if temperatures exceed the safe range. The light blue color code marks its specific trip temperature.
Because the trip temperature is color-coded, this genuine OEM light-blue switch matches your furnace's exact safety spec. A generic or mismatched-color switch can bypass proper protection or cause false lockouts. For a safety-critical component, OEM is strongly recommended.
Easy — Disconnect power, remove the mounting screws, swap the wire terminals, and reinstall. Verify the light-blue color matches the original part. If the switch trips repeatedly, check blower operation and airflow.
