The Goodman 10123529 is a genuine OEM manual reset high-limit switch for the Amana/Goodman AMEC800804BNAB gas furnace. This safety control monitors furnace temperature and opens the circuit to shut down the burners if it detects an overheat or flame-rollout condition, protecting the heat exchanger and household. Because it is a manual reset device, it must be physically reset after a trip — a repeat trip indicates an underlying airflow or combustion problem that should be diagnosed.
The OEM 10123529 is calibrated to the exact trip temperature specified for the AMEC800804BNAB. Because this is a life-safety control, using a generic switch with a different trip point can defeat the furnace's protection or cause nuisance shutdowns. Genuine OEM is the only recommended option for a safety limit.
Easy (2/5). About 15–20 minutes with basic hand tools. Disconnect power before servicing and note wire positions. If the switch trips again after replacement, have a licensed technician diagnose the root cause before returning the furnace to service.
