The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control for AMEC800805DXAB gas furnaces. This high-limit switch monitors heat-exchanger temperature and cuts power to the gas valve if the furnace overheats — protecting against fire and heat-exchanger damage. As a manual-reset device, it requires a deliberate button press to restore operation after a trip, alerting you to underlying airflow or combustion issues.

OEM vs. Generic

Because this is a life-safety component, the OEM Goodman switch is calibrated to the exact trip temperature specified for your furnace. Generic switches with incorrect set points can either fail to protect the equipment or cause repeated nuisance lockouts. We recommend OEM for all safety controls.

Installation Difficulty

Easy to Moderate — Power off the furnace, disconnect the two spade terminals, remove the mounting screws, and swap in the new switch. Typically 15–25 minutes. Always diagnose why the original tripped before replacing.
