The color code identifies its specific trip temperature — this auxiliary limit backs up the primary high-limit, opening the control circuit if a localized area of the furnace exceeds its safe temperature. It protects against blocked airflow, blower failure, and heat build-up around the blower compartment or burner box.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFunction: Auxiliary \/ secondary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eColor Code: Light blue (trip-temperature identifier)\u003c\/li\u003e\n\u003cli\u003eType: Automatic-reset thermal switch\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eFits: Goodman VMS80604BXAA gas furnace\u003c\/li\u003e\n\u003cli\u003eMounting: Bracket\/clip on furnace panel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 0130F00038\u003c\/strong\u003e is matched to the exact trip point the light-blue code represents — critical, because auxiliary limits differ only by temperature rating and are easy to mis-order.
