The genuine Goodman 10123529 Manual Reset Limit Switch is a factory-OEM high-temperature safety control for AMVC800805DNAB gas furnaces and compatible Goodman/Amana models. This rollout/limit switch trips and cuts gas when it senses an overheat or flame-rollout condition, then must be manually reset—an intentional safety feature that flags an underlying issue. If your furnace locks out on a limit fault, this is a common failure point.
Safety limit switches are calibrated to a specific trip temperature. OEM 10123529 guarantees the factory setpoint and terminal configuration; a mismatched generic can trip early (nuisance lockouts) or too late (a real safety hazard). For a life-safety control, OEM is strongly recommended.
Easy — Power off the furnace, unplug the two spade terminals, remove two mounting screws, and swap. A 10–15 minute job. If the switch keeps tripping after replacement, have the heat exchanger and airflow inspected.
