These Nesco dehydrators have a bi-metal thermostat. The surface of the contacts will sometimes corrode and stick together. This causes the unit to heat to a high temperature. This causes the solder to melt or the fuse to blow. Take it apart and clean the contacts with fine sandpaper or thin file. The replacement fuse is a 5x12mm 235 degree 2.5 amp 250 volt thermal fuse available from Radio Shack online or at store.These Nesco dehydrators have a bi-metal thermostat.
