The Goodman 10123529 is a genuine manual-reset limit switch that serves as a critical high-temperature/rollout safety cutout on AMH81205DNBB gas furnaces and related Goodman/Amana models. When it senses an over-temperature or flame-rollout condition, it opens the control circuit to shut the furnace down and must be manually reset — a deliberate safety feature that flags an underlying issue such as restricted airflow or a cracked heat exchanger.

Specifications

Type: Manual reset limit / rollout switch
Function: Normally-closed thermal cutout
Reset: Manual push-button
Terminals: 1/4 in. quick-connect
OEM Part Number: 10123529

OEM vs. Generic

Because this is a life-safety component, the OEM 10123529 is calibrated to Goodman's exact trip temperature and mounting footprint. Generic substitutes may trip early (nuisance shutdowns) or late (dangerous). We recommend genuine OEM for any safety switch.

Install Difficulty

Easy. Typically a 10–20 minute repair: kill power, unplug two spade terminals, remove two screws, and mount the new switch. If the old switch had tripped, diagnose the root cause (airflow, filter, heat exchanger) before returning the furnace to service.
