If you're talking about the Paragon Classic Pop, I don't see any evidence of it having a fuse (in the spare parts list). If the machine has no power at all (ie. heat lamp doesn't turn on, kettle doesn't warm up, motor doesn't turn) I would first check the outlet to make sure it's working then work your way into the machine with a voltmeter, checking each connection to see where the current flow stops. It could be as simple as a bad power switch.
