The Goodman 10123539 Manual Reset Limit Switch is a genuine OEM safety control for the Amana/Goodman AMEC960603BNBB gas furnace. It monitors for abnormal high-temperature or flame-rollout conditions and cuts power to the gas valve to protect the heat exchanger and your home. Because it is a manual-reset device, it stays open after a trip until reset by hand — alerting you to an underlying problem such as restricted airflow.

OEM vs. Generic

The trip temperature and mounting bracket geometry are critical safety parameters. Generic switches with the wrong set point can nuisance-trip or, worse, fail to protect the heat exchanger. This OEM switch is calibrated to Goodman's exact specification.

Install Difficulty

Easy (2/5) — Disconnect power and gas, unplug the two spade terminals, remove the mounting screws, and swap in the new switch. Basic hand tools only. If the switch keeps tripping, diagnose airflow before running the furnace.
