Just to provide an update...I recently got my Advantium 120 working again. In my case...it wasn't a fuse or the thermistor, but TCO sensor.
The sensor must have failed which then burnt up some of the wires and melted one of the plug connectors. I ordered the new part, replaced the wires and added an inline fuse. Should this part fail again...it won't be such a fire hazard.
I included some information that may be helpful to anyone trying to find part numbers (etc.) on parts to repair your Advantium.My epinions review
