The Goodman B1497204 Fusible Link is a genuine OEM thermal safety component engineered for the GUN100-4 gas furnace and compatible GUN100 series models. This 144°C (291°F) thermal cutoff protects your furnace by opening the electrical circuit if a dangerous over-temperature condition occurs, preventing damage to the heat exchanger and surrounding components. When your furnace trips on a high-limit fault or fails to energize, a blown fusible link is one of the most common — and least expensive — culprits.

Specifications

OEM Part Number: B1497204
Type: One-shot thermal fusible link / cutoff
Rated Trip Temperature: 144°C (approx. 291°F)
Fits: Goodman GUN100-4 and GUN100 series furnaces

OEM vs. Generic

This is the factory-specified Goodman OEM link, calibrated to the exact trip temperature your furnace's safety system was designed around. Generic universal links may carry a different trip rating or lead configuration, risking nuisance trips or, worse, failure to open at the correct temperature. For a safety-critical part, OEM is strongly recommended.

Installation Difficulty

Easy (2/5). A basic repair for a qualified technician — disconnect power, remove the failed link, and splice in the replacement. Always confirm what caused the original link to blow (blocked airflow, failed blower, dirty filter) before returning the unit to service.
