Working alongside the primary high limit, the auxiliary limit adds an additional layer of overheat and rollout protection, opening the control circuit and cutting the gas valve if temperatures exceed its rated trip point. The light-blue color code marks its specific temperature rating and must match exactly for safe operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 0130F00038\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Auxiliary Limit Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e ADVC81005CXAA (Furnace)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Normally-closed thermal safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor code:\u003c\/strong\u003e Light Blue (specific trip temperature)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Secondary overheat \/ rollout protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit type:\u003c\/strong\u003e Direct OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a safety device with a coded trip temperature, only the exact OEM part should be used.
