This thermally activated switch opens the control circuit when it senses excessive temperature — such as a blocked flue, failed blower, or flame rollout — shutting the furnace down to prevent heat-exchanger damage and unsafe operation. Because it is a manual-reset device, it must be physically reset by pressing the button after the fault is corrected, which is an intentional safety feature.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset (push-button) thermal limit switch\u003c\/li\u003e\n\u003cli\u003eFunction: Normally closed, opens on overtemperature\u003c\/li\u003e\n\u003cli\u003eApplication: High-limit \/ flame-rollout protection\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GKS91155DXAE furnace\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4\" quick-connect spade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman 10123519\u003c\/strong\u003e is factory-matched to the correct trip temperature for this furnace's heat-exchanger geometry.
