The Goodman 10123529 is a genuine OEM manual-reset high-limit / rollout safety switch for the AMEC800803BNAB furnace and compatible Goodman/Amana models. This safety control opens the circuit and shuts down the furnace if it detects excessive temperature or flame rollout, protecting against overheating and unsafe combustion. Because it is manual-reset, it must be physically reset after a trip — repeated tripping indicates an underlying airflow or combustion fault that should be diagnosed.
Limit switches are calibrated to a specific trip temperature. OEM guarantees the correct rating and mounting for your furnace, so the safety cutout trips exactly when it should. A generic switch with the wrong temperature rating can either nuisance-trip or, worse, fail to protect the unit. For a life-safety component, always use OEM.
Easy (2/5). Usually a 15–30 minute swap: two mounting screws and two spade terminals. Cut power at the disconnect first. If the switch keeps tripping after replacement, have a licensed technician diagnose the root cause before returning the furnace to service.
Confirm your model and serial before ordering. Genuine Goodman OEM safety part.
