The Goodman 10123529 is a genuine OEM manual reset limit (rollout) switch engineered for the AMS81005CXAA gas furnace and compatible Goodman and Amana models. This high-temperature safety control monitors the burner box and heat exchanger area, tripping to cut off gas and ignition if it detects flame rollout or an abnormal temperature rise. Because it is a manual reset device, it holds the circuit open until an operator physically presses the reset button — a deliberate safety design that forces inspection before the furnace can restart.
This is a factory OEM Goodman part with a calibrated, matched trip temperature. Generic universal switches may not share the exact set point or bracket geometry, risking nuisance trips or an improper safety response. For a code-compliant repair that protects the heat exchanger warranty, choose the OEM 10123529.
Easy (1/5). Typically a two-wire swap held by one or two screws — 10 to 15 minutes for most DIYers. Always shut off power and gas before servicing, and investigate the underlying cause (blocked flue, cracked heat exchanger) before resetting a tripped rollout switch.
