Mounted on the burner assembly, this switch detects flame rollout—a dangerous condition where flames escape the heat exchanger—and immediately shuts off the furnace to prevent fire and overheating. A tripped or failed rollout switch is a critical no-heat and safety fault that should never be bypassed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1370145\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 300°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003eReset Type: Manual reset\u003c\/li\u003e\n\u003cli\u003eComponent: Flame rollout limit \/ safety switch\u003c\/li\u003e\n\u003cli\u003eFits Model: AMS80453AXAA (and compatible Goodman\/Amana furnaces)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B1370145 is calibrated to the exact 300°F trip point and terminal configuration your furnace's safety circuit expects.
