This one-time thermal cutout is a last-line safety device: if furnace temperatures climb past the rated limit, the link melts and permanently opens the circuit, de-energizing the furnace to protect against overheating and fire. A blown fusible link is a frequent cause of a completely dead furnace that gets no power to its controls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1497204\u003c\/li\u003e\n\u003cli\u003eType: Fusible thermal link (one-time \/ non-resettable)\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 144°C (approx. 291°F)\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman GUN040-2 gas furnace\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause a fusible link is a safety component, the \u003cstrong\u003eexact temperature rating matters\u003c\/strong\u003e. This genuine Goodman B1497204 is rated precisely at 144°C to match the furnace's design. Generic links with the wrong rating can either fail to protect the unit or trip prematurely. Always replace with the correct OEM rating.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy.\u003c\/strong\u003e A quick, low-cost repair. Disconnect power, unplug or unscrew the old link from its harness, and connect the replacement. Under 15 minutes for most homeowners. Important: a fusible link only blows when the furnace has already overheated — before restarting, confirm the underlying cause (dirty filter, blocked vents, blower failure) has been corrected so the new link doesn't blow again.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058187256179,"sku":"GOODMAN-13111","price":10.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-144-c-fusible-link-thermal-fuse-for-gun040-2-b1497204","provider":"National HVAC Parts","version":"1.0","type":"link"}
