The Goodman 10123529 is a genuine OEM manual reset high-limit switch for the AMEC800603BXAB gas furnace and compatible Goodman/Amana models. This safety control monitors heat-exchanger and plenum temperature and shuts off the burners if the furnace overheats, protecting the unit and your home.

OEM vs. Generic

OEM limit switches are calibrated to the exact trip temperature specified for your furnace. Because this is a safety-critical component, a generic switch with a different set point can either nuisance-trip or fail to protect against genuine overheating. OEM is strongly recommended for safety controls.

Installation

Difficulty: Easy–Moderate. With power off, disconnect the wiring, unscrew the old switch, and mount the replacement in the same location and orientation. Typically 15–20 minutes. If the switch has been tripping, diagnose the airflow/overheating cause before returning the furnace to service.
