The red cap denotes a distinct trip-temperature calibration from the standard switch — it is critical to match the correct color\/setpoint to the location it protects (e.g., rollout vs. main limit). This switch opens the gas-valve or burner circuit on an overheat condition and requires a manual push to reset, flagging that a root-cause airflow or flame issue needs attention.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 10123535\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e Goodman GKS90904CXAD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual reset limit switch (red)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Over-temperature \/ rollout safety lockout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e Quick-connect spade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Push-button manual\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003eOEM Goodman red switch\u003c\/strong\u003e carries the precise factory setpoint your furnace's safety chain was designed around.
