The Goodman 10123517 is a manual reset rollout limit switch engineered for the ACSH960905DXAA 96% AFUE gas furnace and compatible Goodman/Amana models. This factory safety control monitors the burner compartment for flame rollout and shuts off the gas valve if abnormal heat is detected, protecting your furnace and home from unsafe combustion conditions.
Our OEM Goodman switch is calibrated to the exact factory trip point and bracket geometry, ensuring a true bolt-in fit and reliable safety operation. Generic substitutes may use different trip temperatures or mounting tabs that require modification and can nuisance-trip. For a critical safety control, OEM is strongly recommended.
Easy — two-screw mount with quick-connect terminals. Always disconnect power and gas before servicing. A multimeter continuity test confirms a tripped vs. healthy switch.
