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 \u003cstrong\u003emanual reset\u003c\/strong\u003e 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.\u003c\/p\u003e\u003cp\u003eA 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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Manual-reset high-limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 10123529\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Model:\u003c\/strong\u003e GDH80403ANBC gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Type:\u003c\/strong\u003e Normally closed, opens on overtemperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual push-button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Combustion safety \/ rollout protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is factory-calibrated to the exact trip temperature and mounting bracket for the GDH80403ANBC — important for a safety component.
