This one-time thermal safety link opens the low-voltage control circuit if the furnace exceeds its rated temperature — for example, from a blocked filter, failed blower, or restricted airflow — shutting the unit down before heat damages the cabinet or wiring. Once tripped, the link is non-resettable and must be replaced.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Fusible link \/ thermal cutoff (one-shot)\u003c\/li\u003e\n\u003cli\u003eTrip temperature: 144°C (291°F)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GDI125-5 furnace\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1497204\u003c\/li\u003e\n\u003cli\u003eFunction: Opens control circuit on overtemperature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is the \u003cstrong\u003efactory OEM Goodman\u003c\/strong\u003e link calibrated to the precise 144°C trip point specified for the GDI125-5.
