The genuine Goodman 10123519 manual reset limit switch is the high-temperature safety control for the AMH951155DXAG gas furnace. This normally-closed switch opens to shut off the burners if the furnace overheats — typically from restricted airflow, a dirty filter, or a blower fault. Because it is a manual reset device, it stays open after a trip and must be reset by hand, ensuring the underlying problem gets attention instead of the furnace silently short-cycling on an intermittent fault.

Part number: 10123519
Type: Manual reset high-limit / rollout safety switch
Configuration: Normally closed, opens on overheat
Function: Cuts burner circuit on excess temperature
Equipment: Gas furnace
Fits model: AMH951155DXAG and compatible Goodman/Amana furnaces

OEM vs. Generic: Limit switches trip at a specific temperature. A generic switch with a different open temperature can trip too early (nuisance lockouts) or too late (letting the heat exchanger run dangerously hot). The OEM 10123519 is calibrated to your furnace's exact limit temperature, so it protects the heat exchanger without false trips.

Install difficulty: Easy (1/5). Turn off power to the furnace, note the wiring, and unscrew the old switch from its bracket. Mount the new 10123519 in the same location and orientation, transfer the terminals, and restore power. After install, press the reset button and run a full heat cycle to confirm normal operation. If the new switch trips again, investigate airflow before assuming a part fault.

Keep your furnace safe from overheating with the exact OEM Goodman manual reset limit switch for your AMH951155DXAG.
