How does a fusible link look if bad?

A bad fusible link typically shows visible signs of damage, such as charring, melting, or discoloration. It may appear burnt or blackened, and the insulation might be cracked or frayed. In some cases, the link may be completely broken or severed, indicating it has failed to function properly. If you notice these signs, it's important to replace the fusible link to ensure safety and proper electrical function.
