The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control for the GDH80403ANBC gas furnace. This normally-closed thermal switch monitors for excessive temperature or flame rollout at the burner box; if it senses an overheat condition, it opens the circuit and shuts the furnace down to prevent damage to the heat exchanger and reduce fire risk. Because it is a manual reset device, it will not auto-recover — a technician must press the reset button after correcting the underlying fault, which is by design so hazardous conditions are investigated.

A tripped or failed limit switch is a common cause of a furnace that starts and then shuts off, or that will not fire at all. Repeated tripping usually points to a real problem such as a blocked flue, dirty burner, or restricted airflow that should be diagnosed before returning the unit to service.
