This normally-closed thermal safety monitors a secondary location in the furnace and opens the control circuit if it senses excessive temperature — providing backup protection alongside the primary limit. The blue color code corresponds to a specific trip temperature, so matching the exact part is critical.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Auxiliary limit \/ thermal safety switch\u003c\/li\u003e\n\u003cli\u003eColor Code: Light blue (temperature-specific)\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eApplication: 80% AFUE gas furnaces\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement for AMH80805CNAA\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe light-blue color code is not cosmetic — it marks the switch's exact set-point. Installing a generic limit with a different trip temperature can cause nuisance shutdowns or defeat the intended safety margin.
