This secondary thermal switch backs up the primary limit, opening the control circuit if it senses excessive heat near the blower deck or burner area — protection against blocked airflow, blower failure, or flame rollout. The light-blue color code identifies its specific trip temperature, so matching the exact part is essential.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFunction: Auxiliary \/ secondary high-limit safety cutout\u003c\/li\u003e\n\u003cli\u003eColor code: Light blue (temperature-specific)\u003c\/li\u003e\n\u003cli\u003eReset: Snap-disc thermal disc\u003c\/li\u003e\n\u003cli\u003eMounting: Factory bracket per furnace spec\u003c\/li\u003e\n\u003cli\u003eFits: AMS80403AXAD and compatible 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eAuxiliary limits are color-coded to a precise open temperature. Installing a switch with the wrong trip point — easy to do with unmarked generics — either nuisance-trips the furnace or removes the intended protection.
