The B1497204 is a genuine Goodman thermal fusible link engineered as a one-time safety cutout for the GUP075-3A gas furnace and compatible Goodman/Amana models. When flue or heat-exchanger temperatures exceed the rated 144°C (291°F) threshold, the link opens the circuit to shut the furnace down and prevent an overheat condition. It is a critical safety component that should always be replaced with a like-for-like OEM part.
Genuine OEM Goodman links are calibrated to the exact 144°C rating your furnace's safety circuit was designed around. Generic thermal fuses may carry a different trip point or slower response, which can cause nuisance shutdowns or, worse, fail to protect the appliance. For a safety-critical component, OEM is strongly recommended.
Easy (1/5). A basic replacement for anyone comfortable turning off power and gas, removing the burner-compartment cover, and swapping a single wired link. Always disconnect power at the breaker before servicing. If the link has tripped, diagnose and correct the root cause (blocked flue, failing inducer, or restricted airflow) before returning the unit to service.
