What is a EGI fuse?

An EGI (Electronic Gas Ignition) fuse is a safety device used in electronic ignition systems, commonly found in gas appliances like furnaces and water heaters. It serves to protect the ignition circuit by interrupting the electrical flow in case of a fault or overload, preventing potential damage to the ignition system or other components. If the fuse blows, it typically indicates a malfunction that needs to be addressed before the system can operate safely again.
