A fusible link is a safety device used in electrical circuits. It consists of a piece of metal that has a low melting point. When the current flowing through the circuit exceeds the safe limit, the fusible link will melt and break the circuit, preventing damage to the appliances or wiring.
If the fusible link is bad, it means that it has melted and broken the circuit. This will prevent electricity from flowing to the appliances or wiring, which will cause them to stop working.
