Tip & How-To about Nesco 700W 5-Tray Professional Food Dehydrator

Nesco Dehydrator Quits Working or Overheats

These Nesco dehydrators have a bi-metal thermostat. The surface of the contacts will sometimes corrode and stick together or short with the corrosion. It can be intermittent. This causes the unit to heat to a high temperature. This causes solder to melt or the thermal fuse to blow. Take it apart and clean the contacts of the thermostat with fine sandpaper or thin file. If needed the replacement fuse is a 5x12mm, 235 degree 2.5 amp 250 volt thermal fuse available from Radio Shack online or at store. An ohm meter will tell you if the fuse is bad.

My Salton Food dehydrator just stopped working. Turned it on for the first time today and it remained on for about 10 minutes and now wont turn back on.

If this is a Salton dehydrator that stopped working why are you referencing Gardenmaster dehydrators which is Nesco/American Harvest?

Take apart the bottom unit that contains the heating element. Hopefully it's put together with phillips screws. Mine are not. I'd have to drill out the brads that are holding it together. Once it's apart, use an Ohmmeter to check the heating element. Be sure to disconnect the fan from the heating element when ohmming out the element. If the element is open electrically, replace it. Good luck in finding a place to purchase a new element.
