The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for the AMS81405DNBB and compatible Goodman/Amana gas furnaces. This normally-closed switch opens and cuts power to the gas valve if it senses an overheat or flame-rollout condition, protecting the heat exchanger and cabinet. Because it is a manual-reset design, it stays tripped until a technician presses the reset button — a deliberate safeguard that flags a fault needing inspection rather than silently cycling.

OEM vs. Generic

The trip temperature and mounting footprint of a limit switch are safety-critical. OEM part 10123529 is calibrated to the exact set point your furnace's certification requires. Generic switches with the wrong trip point can either nuisance-trip or, worse, fail to protect the heat exchanger. For a safety device, always install OEM.

Install Difficulty

Easy (2/5). Two spade terminals and two mounting screws. Shut off power and gas first. If the old switch tripped, diagnose the root cause (blocked airflow, failed blower) before returning the furnace to service.
