The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control for GDH80403AXBD gas furnaces. This high-limit switch monitors heat-exchanger and plenum temperature and cuts power to the gas valve if the furnace overheats — protecting against blocked airflow, a failed blower, or a dirty filter. As a manual-reset device, it must be physically reset after a trip, alerting the homeowner that a fault occurred.

  • Part Number: 10123529
  • Type: Manual reset high-limit switch
  • Function: Over-temperature safety cutoff
  • Fits: Goodman GDH80403AXBD and compatible furnaces
  • Reset: Manual (push-button)
  • Electrical: Normally closed, opens on temperature rise

OEM vs. Generic: The genuine Goodman switch is calibrated to the exact trip and reset temperatures specified for this furnace platform. Generic limit switches with incorrect setpoints can nuisance-trip or, worse, fail to open at the safe temperature. Because this is a life-safety component, OEM is the recommended choice.

Install difficulty: Easy. De-energize the furnace, unplug the two spade terminals, remove the mounting screws, and install the replacement in the same orientation. No calibration needed. If the switch keeps tripping, diagnose the underlying airflow problem before returning the unit to service.
