This thermal switch monitors heat-exchanger and supply-air temperature and opens the gas circuit if the furnace overheats — protecting the heat exchanger, blower, and your home from dangerous high-temperature conditions. Because it is manual-reset, it requires a deliberate button press to restore operation after a trip, alerting the homeowner that an underlying airflow or sequencing fault needs attention.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Goodman (OEM)\u003c\/li\u003e\n\u003cli\u003ePart Number: 10123517\u003c\/li\u003e\n\u003cli\u003eType: Manual reset high-limit (rollout\/overheat) switch\u003c\/li\u003e\n\u003cli\u003eFunction: Normally closed, opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM switch is calibrated to Goodman's exact trip-temperature spec and mounting footprint, so it seats flush against the burner box and reads heat correctly.
