The Goodman 10123529 is a genuine OEM manual reset limit switch designed for Goodman and Amana gas furnaces, including the AMH80604BXBB 80% AFUE model. This normally-closed thermal safety switch opens and cuts power to the gas valve if it senses abnormal heat — typically from flame rollout or a blocked flue — protecting the furnace and your home from unsafe operation. Unlike auto-reset controls, it requires a manual button press to restore operation, alerting the homeowner or technician that a safety event occurred and needs investigation.
This factory part is calibrated to the exact trip temperature specified for your furnace. Generic switches with mismatched trip points can nuisance-trip or, worse, fail to open when needed. For a life-safety component, the OEM part ensures correct protection.
Easy to moderate. Power down the furnace, disconnect the two spade terminals, unscrew the switch, and install the replacement in the same orientation. Always determine why the original tripped before returning the unit to service.
