The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-limit safety control for Goodman and Amana gas furnaces, including the ACVC80803BXBD. This switch monitors furnace temperature and shuts off the gas/burner circuit if it detects an overheat or flame-rollout condition. Because it is a manual reset device, it requires a deliberate button press to restore operation after a trip — alerting the homeowner that a fault occurred.
The OEM 10123529 is calibrated to the precise trip temperature specified for this furnace. Substituting a generic switch with a different setpoint can either nuisance-trip or, worse, fail to trip when needed — defeating a critical safety function. Always use the exact OEM limit switch.
Easy to Moderate — Replacement involves disconnecting power, unplugging the two leads, unbolting the switch, and mounting the new one. While mechanically simple, this is a safety control: if the switch has tripped, the underlying cause (blocked airflow, dirty filter, failed blower, cracked heat exchanger) must be diagnosed by a technician before returning the furnace to service.
Confirm fitment against your furnace's parts diagram before ordering.
