Like its companion switch, it protects the furnace and home by opening the control circuit if it senses excessive heat or flame rollout near the burner assembly or heat exchanger. It differs from part 10123517 by its factory trip temperature\/mounting position — furnaces in the GCH90 series use more than one rollout switch at different points, so verify the number stamped on your original before ordering. A furnace that runs, then abruptly stops with a rollout fault, often points to one of these switches.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePart number: 10123519\u003c\/li\u003e\n\u003cli\u003eComponent: Manual reset rollout \/ high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: De-energizes furnace on overheat or flame rollout\u003c\/li\u003e\n\u003cli\u003eReset type: Manual push-button\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GCH90453BXAB and related GCH90 series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch carries the precise temperature rating and bracket geometry specified for this position in the furnace.
