The Goodman 10123529 is a genuine OEM manual-reset limit (flame rollout) switch for AMH80804BXAA and compatible Goodman/Amana gas furnaces. This safety control trips and shuts off the gas valve if it senses flame rollout or excessive heat at the burner box, protecting against unsafe combustion. Because it is manual-reset, a tripped switch requires a physical reset — and usually indicates an underlying issue (blocked flue, dirty burners, cracked heat exchanger) that should be diagnosed.
OEM 10123529 switches are calibrated to the exact factory trip temperature for this furnace's burner box. Generic switches may trip at different setpoints, causing nuisance shutdowns or, worse, failing to protect. For a safety control, OEM is strongly recommended.
Easy (1/5). Power off the furnace, unplug the two wires, remove one or two mounting screws, and install the new switch. If the old switch was tripped, have the root cause inspected by an HVAC pro before returning the unit to service.
