The Goodman 10123529 is a genuine OEM manual-reset high-limit safety switch for the ADVC80703BXAA furnace and related Goodman/Amana models. This normally-closed thermal switch opens the ignition circuit if it senses an overheat or flame-rollout condition, shutting the furnace down to protect the heat exchanger and prevent unsafe operation. Because it is manual-reset, it must be pressed to restore operation after a trip — a deliberate safety design that flags a problem needing attention.
This genuine OEM Goodman switch is calibrated to your furnace's exact trip temperature. A generic switch with the wrong setpoint can nuisance-trip or, worse, fail to trip when it should. For a safety-critical control, OEM is strongly recommended.
Easy (2/5) — Cut power, unplug the two spade terminals, unscrew the old switch, mount the new one, and reconnect. Basic tools and ~15–20 minutes. If the switch keeps tripping, diagnose airflow/heat-exchanger issues before repeated resets.
