Color-coded light blue for its distinct trip temperature, this auxiliary limit provides a backup overheat\/rollout cutout in addition to the primary high-limit, opening the control circuit to stop the burner if a secondary location exceeds safe temperature. It protects against blocked airflow, blower failure, and flame rollout conditions.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary limit \/ secondary thermal switch (normally closed)\u003c\/li\u003e\n\u003cli\u003eColor Code: Light Blue\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003cli\u003eFits Model: ACSS921005CNAA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003elight-blue color code\u003c\/strong\u003e designates a specific cut-out temperature different from the primary pink limit.
