This safety-critical control monitors flame rollout and over-temperature conditions inside the burner compartment, cutting power to the gas valve if unsafe heat is detected. Because it requires a manual reset, it forces a service inspection after a trip — exactly what a properly designed furnace safety chain should do.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Manual reset rollout \/ limit switch\u003c\/li\u003e\n\u003cli\u003eReset style: Manual push-button reset\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana furnaces including AMSS921205DNAA\u003c\/li\u003e\n\u003cli\u003eFunction: Flame rollout \/ high-limit safety cutoff\u003c\/li\u003e\n\u003cli\u003eTerminals: Standard 1\/4\" quick-connect spades\u003c\/li\u003e\n\u003cli\u003eBrand: Genuine Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman OEM switch is calibrated to the exact trip temperature specified for your furnace, ensuring the safety chain behaves as the manufacturer intended and preserving warranty coverage.
