Repairing a Nesco American Harvest Dehydrator
Nesco American Harvest Dehydrator Repair Guide
This comprehensive guide will walk you through the process of repairing your Nesco American Harvest Dehydrator. The repair process involves replacing a faulty fuse, which is a relatively simple and inexpensive fix.
|
Tools and Materials Needed
- A new fuse (available online for a few dollars)
- Needle-nosed pliers
- A small flathead screwdriver
- A star pattern screwdriver (optional)
- Zip ties
|
Disassembly and Fault Identification
To begin the repair process, you will need to disassemble your Nesco American Harvest Dehydrator. Start by removing the eight smaller screws that hold the heating element cover in place. Remove the screws in a star pattern to ensure even pressure.
Once the screws are removed, carefully lift the cover off the dehydrator. You will see the fan unit and the heating element underneath. Identify the faulty fuse, which is usually located near the heating element.
|
Removing the Faulty Fuse
Carefully remove the faulty fuse from the heating element. Use a small flathead screwdriver to loosen the clips holding the fuse in place. Once the clips are loose, use needle-nosed pliers to pull the leads of the fuse out of the crimps.
|
Installing the New Fuse
Take the new fuse and insert it into the clips on the heating element. Make sure the black end is to the left, facing the negative side of the circuit or the black wire. If your leads are too long, trim off the excess.
Seat the fuse into the crimp connectors and squeeze the ends closed using needle-nosed pliers on both sides. Verify that there is continuity between the black wire and both the red and white wires.
|
Reassembly
Now it's time to reassemble your Nesco American Harvest Dehydrator. Place the heating element back onto the black cover, making sure the small pegs are aligned correctly. Three of them are long and one is short. The short one goes in front of the fuse, while the long ones go into the three holes.
Replace the four screws that hold the heating element onto the cover. On the plastic housing, keep track of where the plastic cord guide is located. When placing the heating element and the cover back into place, make sure the wires are on the same side as the other.
|
Final Reassembly and Testing
Flip the unit back over and adjust the position of the cover until it locks into place. Then replace the other side of the fan unit and replace the eight smaller screws for the heating element cover.
Reattach the wires together, making sure to match them up based on your labels. Reattach the wire clips to the blades on the thermal controller. Zip tie the wires back together to keep them organized.
Finally, plug in your Nesco American Harvest Dehydrator and test it to ensure it's heating properly. Check that you're able to set the min and max temperatures correctly.
|
Conclusion
With a new fuse installed, your Nesco American Harvest Dehydrator should be working again. This repair process is relatively simple and inexpensive, saving you money compared to buying a brand new dehydrator.
Remember to always follow proper safety precautions when working with electrical appliances, and consult the user manual if you're unsure about any part of the repair process.
