The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-limit safety control engineered for the Amana / Goodman AMEH800603BNAA 80% AFUE furnace and compatible multi-position models. This switch monitors heat-exchanger temperature and cuts power to the burners if the furnace overheats, protecting the unit from damage caused by restricted airflow, a failed blower, or a dirty filter. Because it is a manual reset style, it will not automatically re-close after tripping — a deliberate design that forces a technician to inspect the cause before restoring heat.

Part number: 10123529
Type: High-limit / rollout, manual reset
Function: Overheat safety cutout
Fits: AMEH800603BNAA and related Goodman/Amana gas furnaces
Terminals: 1/4" quick-connect spade

OEM vs. Generic

The OEM Goodman 10123529 is calibrated to the exact trip temperature specified for your furnace, guaranteeing correct safety behavior and a factory-matched fit. A generic equivalent covers the same function at a lower cost but may vary slightly in trip tolerance or terminal orientation — a solid budget choice for out-of-warranty repairs.

Install difficulty: Easy. Typically a two-screw swap with two push-on wire connectors. Always shut off gas and electrical power before servicing. Estimated time: 10–15 minutes for a DIYer comfortable working inside a furnace cabinet.
