This secondary (auxiliary) limit provides backup overheat protection — often mounted near the blower or a rollout-prone area — cutting the heating circuit if temperatures exceed safe levels. The light blue color code identifies its specific trip rating, which differs from the primary limit, so exact matching is essential.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\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 Limit switch — auxiliary \/ secondary high limit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code:\u003c\/strong\u003e Light Blue (denotes trip temperature rating)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman ADVC81155CXAA furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Backup overheat safety cutoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Direct OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e auxiliary limit is calibrated to the precise temperature and reset behavior specified for this position in the furnace.
