The red button designates it as a manual-reset device at a specific trip point in the burner\/heat-exchanger safety chain. When temperatures exceed the rated cutout, the switch opens and shuts down the gas valve, then holds open until an operator presses the reset — ensuring the fault is investigated before the furnace fires again.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual reset high-limit switch (SPST, normally closed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIdentifier:\u003c\/strong\u003e Red reset button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e High-temperature \/ rollout safety cutout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual push-button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e Quick-connect spade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GKS90904CXAF and compatible 90%+ furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman OEM (Amana compatible)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine \u003cstrong\u003e10123535\u003c\/strong\u003e is calibrated to Goodman's exact factory trip temperature — the red housing signals a different setpoint than similar-looking switches, so substituting the wrong color or a generic equivalent can cause either nuisance lockouts or a dangerously delayed trip.
