The Goodman 0130F00038 Auxiliary Limit Switch (light-blue coded) is a genuine OEM thermal safety control for the Goodman/Amana AMS80603AXAD gas furnace. This normally-closed switch opens the control circuit and shuts down the burner if it senses an over-temperature condition, protecting the heat exchanger and blower housing from heat damage caused by restricted airflow or a failed blower.
The light-blue color code identifies a specific factory trip temperature. Installing the correct OEM switch is a safety requirement — a generic limit rated at the wrong temperature can either nuisance-trip or, worse, fail to trip when it should. Always match the OEM color/temperature code exactly.
Easy. Disconnect power, unplug the two spade terminals, remove the mounting screws, and install the new switch in the same orientation. About 10 minutes. Confirm the airflow problem that caused the original trip is resolved before returning the furnace to service.
