Wired in series with the low-voltage control circuit, this link opens permanently if the blower compartment or heat exchanger area exceeds its rated temperature, shutting the furnace down to prevent overheating. If your furnace is completely dead after an overheat event or blocked airflow, a blown fusible link is a frequent cause.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: One-shot fusible thermal link (safety cutoff)\u003c\/li\u003e\n\u003cli\u003eRated temperature: 144°C \/ 291°F open point\u003c\/li\u003e\n\u003cli\u003eCircuit: 24 VAC control-circuit interrupt\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GUI050-2 and compatible furnace models\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1497204\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a \u003cstrong\u003esafety device\u003c\/strong\u003e, the OEM part with its exact 144°C trip rating is essential — never substitute a link with a different temperature rating. Using a higher-rated or generic link defeats the furnace's overheat protection and creates a fire hazard. The factory Goodman part guarantees the correct rating and lead length.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy to moderate\u003c\/strong\u003e — the link plugs into the control wiring, but you must first diagnose and correct the underlying overheat cause (dirty filter, blocked ducts, failing blower). Disconnect power before replacing. A quick job for a technician; DIYers should confirm airflow is restored before running.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058185552243,"sku":"GOODMAN-13063","price":10.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-144-c-fusible-link-thermal-fuse-for-gui050-2-b1497204","provider":"National HVAC Parts","version":"1.0","type":"link"}
