The Goodman B1497204 is a genuine OEM 144°C fusible link (thermal cutoff) for the Goodman GUP115-5 furnace and compatible Goodman/Amana models. This one-shot thermal safety device is wired in series with the control circuit and permanently opens if the internal temperature exceeds 144°C (291°F), shutting the furnace down to prevent overheating from a blocked filter, failed blower, or restricted airflow. Because it is non-resettable, a blown link means the furnace goes dead and the underlying cause must be corrected before replacement.
The OEM Goodman link is calibrated to the exact 144°C rating specified for this furnace. Never substitute a higher-temperature or jumpered link — the correct trip temperature is a life-safety spec, and OEM guarantees it. Generic links must be verified for an identical 144°C rating and lead style.
Easy (1/5). Cut power, splice or plug the new link into place matching the original routing, and secure the leads. About 15 minutes — but always diagnose and fix the airflow or blower fault that caused the original to blow.
Disconnect power before servicing. Replacing a fusible link without correcting the overheat cause will simply blow the new one.
