This thermally activated switch is a critical safety device: if it detects an overheat or flame-rollout condition at the burner box or heat exchanger, it opens the control circuit and shuts down the furnace to prevent damage and fire hazard. Because it is a \u003cem\u003emanual reset\u003c\/em\u003e switch, it stays open until an operator presses the button — a tripped switch signals a real problem (blocked flue, cracked heat exchanger, dirty burners) that should be diagnosed, not just reset.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePart number: 10123517\u003c\/li\u003e\n\u003cli\u003eComponent: Manual reset rollout \/ high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Opens gas\/control circuit 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 is calibrated to the exact factory trip temperature for this furnace's heat exchanger.
