Rated to open at \u003cstrong\u003e120°F\u003c\/strong\u003e, this auxiliary limit monitors secondary airflow and enclosure temperature, shutting down the burners before heat can build to unsafe levels. It is a factory-calibrated safety device — matching the exact trip point is critical, so an OEM replacement is strongly recommended over generic guesses.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1370155\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Auxiliary \/ rollout limit protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 120°F (open on rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman OEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Fit:\u003c\/strong\u003e ADV81155CXA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is the genuine Goodman part with the precise 120°F calibration and mounting footprint the furnace was designed around.
