The Goodman 10123538 Manual Reset Limit Switch is a genuine OEM high-temperature safety cutoff for the AMEC960403ANAA gas furnace and compatible Goodman/Amana models. It monitors for abnormal heat — such as a flame rollout or overheating condition — and opens the control circuit to shut down the burners before damage or a hazard occurs. Because it is a manual reset device, it stays open after a trip until an operator physically presses the reset button, ensuring the underlying fault is investigated rather than silently cycling.

OEM vs. Generic

Safety controls are the wrong place to save a dollar. The OEM Goodman 10123538 is calibrated to the exact trip temperature and mounting footprint your furnace was certified with. Generic switches may trip at the wrong setpoint — nuisance-tripping during normal operation or, worse, failing to trip when they should. Choose OEM for guaranteed calibration.

Installation Difficulty

Easy (2/5). Shut off power and gas at the furnace. Disconnect the two spade terminals, remove the mounting screws, install the new switch in the same orientation, and reconnect the leads. A multimeter continuity check is recommended after install. Typical replacement takes 15–20 minutes.

Restore your furnace's overheat protection with the genuine Goodman 10123538 manual reset limit switch.
