It may not be the iron that is the problem. It might be what else is on that same circuit that you plug the iron into. To check the problem out, unscrew the fuse and see what else on the circuit shuts off. If there are any loads that can be unplugged do so. Then try the iron again and see if the fuse blows. Try the iron in another plug from a different circuit, if a different fuse blows then its time to get a new iron.

A fuse that keeps blowing is an indication of a malfunctioning ignition. The ignition may be the culprit or the wiring leading to the ignition may be the problem.

Unplug the ECC fuse. If the fuse does not blow, then hook up the ECC. If the fuse blows then the ECC will need to be replaced.
