The Goodman B1497204 Fusible Link is a genuine OEM 144°C (291°F) thermal fuse for the GUN040-2 gas furnace. This one-time thermal cutout is a last-line safety device: if furnace temperatures climb past the rated limit, the link melts and permanently opens the circuit, de-energizing the furnace to protect against overheating and fire. A blown fusible link is a frequent cause of a completely dead furnace that gets no power to its controls.

Specifications

OEM Part Number: B1497204
Type: Fusible thermal link (one-time / non-resettable)
Trip Temperature: 144°C (approx. 291°F)
Compatibility: Goodman GUN040-2 gas furnace
Brand: Goodman (genuine OEM)

OEM vs. Generic

Because a fusible link is a safety component, the exact temperature rating matters. This genuine Goodman B1497204 is rated precisely at 144°C to match the furnace's design. Generic links with the wrong rating can either fail to protect the unit or trip prematurely. Always replace with the correct OEM rating.

Installation Difficulty

Easy. A quick, low-cost repair. Disconnect power, unplug or unscrew the old link from its harness, and connect the replacement. Under 15 minutes for most homeowners. Important: a fusible link only blows when the furnace has already overheated — before restarting, confirm the underlying cause (dirty filter, blocked vents, blower failure) has been corrected so the new link doesn't blow again.
