This one-shot safety device is wired in the control circuit and permanently opens if the furnace cabinet reaches an unsafe temperature — for example due to a blocked flue, failed blower, or overheating condition. If your furnace is completely dead with no control voltage, a blown fusible link is a common and inexpensive fix.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: B1497204\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 144°C (291°F)\u003c\/li\u003e\n\u003cli\u003eType: One-time thermal fusible link (non-resettable)\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat safety cutout\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GUP100-4A furnace\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a safety cutout, the trip temperature must be exact.
