This thermally activated switch monitors heat exchanger and burner-area temperature and opens the control circuit if an overheat or flame-rollout condition occurs, shutting down the burners to protect against fire and cracked heat exchangers. Because it is a \u003cstrong\u003emanual reset\u003c\/strong\u003e device, it must be physically reset with the button after tripping — a deliberate design that forces inspection of the underlying cause before the furnace can restart.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123517\u003c\/li\u003e\n\u003cli\u003eType: Manual reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eReset: Manual (push-button)\u003c\/li\u003e\n\u003cli\u003eFunction: Opens circuit on overtemperature to shut down burners\u003c\/li\u003e\n\u003cli\u003eCompatible Model: GCH90704CXAA (and related Goodman\/Amana furnaces)\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are a safety-critical component, and trip temperature is not something to guess at. A generic switch with the wrong open\/close set point can either nuisance-trip or, worse, fail to trip when needed. The OEM 10123517 is calibrated to Goodman's exact temperature specification for the GCH90704CXAA, ensuring the furnace shuts down at the correct threshold.
