The red button designates a specific trip-temperature calibration in Goodman's limit-switch family, so matching the exact color-coded part number ensures the furnace's overheat protection trips at the temperature the manufacturer engineered for this model. When the heat exchanger area exceeds the safe threshold, the switch opens the control circuit and shuts down the burners until it is manually reset.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 10123535\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual reset high-limit safety switch (red)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual (red press-to-reset button)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GKS90905DXAB (Goodman gas furnace)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Opens burner circuit on over-temperature\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The genuine Goodman 10123535 carries the correct color-coded trip point, mounting pattern, and terminals for the GKS90905DXAB.
