This thermal safety device monitors temperature at the heat exchanger or burner area and opens the control circuit if it detects an overheat or flame-rollout condition, shutting the furnace down to prevent damage and hazard. Unlike an auto-reset limit, the manual reset design requires a technician to press the button and confirm the fault is cleared — a deliberate safety feature. A tripped or failed switch is a common cause of a furnace that won't fire or locks out on ignition.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123529\u003c\/li\u003e\n\u003cli\u003eType: Manual reset high-limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003cli\u003eCompatible Model: GDH80403AXBA\u003c\/li\u003e\n\u003cli\u003eFunction: Normally closed thermal safety cutout\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman limit switches are calibrated to the exact trip temperature your furnace's safety design requires.
