This one-time safety fuse is wired into the control circuit and permanently opens if internal temperatures reach 144°C (about 291°F) — protecting the furnace and home from overheating caused by blocked airflow, a stuck blower, or a failed limit. When a fusible link blows, the furnace goes completely dead with no ignition, which points to an over-temperature event that must be diagnosed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\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: Over-temperature safety cutout\u003c\/li\u003e\n\u003cli\u003eCompatible model: Goodman GUI100-3 furnace\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1497204\u003c\/li\u003e\n\u003cli\u003eNormally-closed, opens permanently on over-temp\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eAs a \u003cstrong\u003ethermal safety device\u003c\/strong\u003e, the exact 144°C rating is what makes this link protective.
