This auxiliary high-limit backs up the primary limit, monitoring a secondary hot spot in the furnace cabinet. If temperatures exceed its rating — typically from restricted airflow or a blower failure — it opens the circuit and interrupts the gas valve to protect the heat exchanger and surrounding components.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eColor Code: Light Blue (identifies trip rating)\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary high-limit \/ overheat safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Secondary overheat protection\u003c\/li\u003e\n\u003cli\u003eCompatibility: AMEH800805CXAB and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe light-blue color code corresponds to a specific factory trip temperature, and the bracket is shaped to sit at the correct sensing location.
