Wired in series with the blower or control circuit, this one-time thermal cutoff permanently opens if the cabinet reaches an unsafe temperature — a last-line safety device that protects against runaway overheating when other limits fail. Unlike a resettable limit switch, a blown fusible link must be replaced, and a link that has opened is a signal to investigate airflow restrictions or a stuck blower.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 144°C (≈291°F)\u003c\/li\u003e\n\u003cli\u003eType: non-resettable one-shot thermal link\u003c\/li\u003e\n\u003cli\u003eFunction: over-temperature safety cutoff\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GUI100-2 furnace\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1497204\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe value of a thermal link is entirely in its calibrated melt point. The OEM B1497204 is certified to open at exactly 144°C with the correct lead length and terminals for a direct fit. Substituting a generic link with a different rating defeats the furnace's safety design — always match OEM spec on thermal cutoffs.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy.\u003c\/strong\u003e Disconnect power, unclip the two leads, and splice or plug in the replacement.
