The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for the AMVC80804CNBC gas furnace and compatible Goodman/Amana models. This normally-closed switch opens to cut power to the gas valve when the furnace overheats — typically from a blocked flue, failed blower, or restricted airflow. Because it is a manual reset device, it must be reset by hand after tripping, forcing a technician to diagnose the underlying cause rather than allowing repeated auto-cycling.
The OEM 10123529 is calibrated to the exact trip temperature specified for this furnace's heat exchanger and rollout location. Generic or mis-rated limits can trip too early (nuisance lockouts) or too late (a genuine safety hazard). For a life-safety control, always use the OEM-specified switch.
Easy — Cut power at the disconnect, unplug the two spade terminals, unscrew the switch, and mount the replacement in the same orientation. Verify continuity and confirm the furnace fires and cycles normally. Have a qualified technician determine why the original tripped.
