Question: Has anyone had a problem with the product not running.  No noise, fan or heat?
Document: Simple design and easy to use. Fast dehydrating. Fan does make some noise (about like a microwave), but i use it in the garage, so no problem.
I put the Excalibur in the basement because I don't use it everyday. The fan noise isn't really objectionable, but I think I'd want to turn it off when having company if it were in my kitchen. In the basement, no problem. It does a great job with the dehydrating!
The lovely white noise they put out can put me to sleep in about 15 minutes--because I have to keep a fan running to sleep because of a very noisy snoring husband. So GET USED TO IT. It will be worth it.
It dehydrates food like it is supposed to. High capacity. I have done 15lbs of bananas at once. I have it in the other room so the fan noise (no horribly loud but noticeable) is no bother.I insulated all sides, top and bottom of mine (taking care to keep the air circulation as designed. I don't understand why they don't come insulated. It makes no sense to me to have it radiating heat to the outside world when it is needed only inside the box.
It has a fan, it makes a whirring noise. I have no problems having a normal conversation in my kitchen with it running. I leave it on overnight and don't hear a thing from my bedroom. The dog doesn't howl at it.- Fairly easy to clean, seems to be a decent quality items, I've had zero issues with it after owning and using for a bit over three months. We've used it roughly a dozen times.- Glad we made the purchase.
Prior to getting this machine a week ago, my only dehydrator experience was a small Ronco product, which for the small things I did was a great product. However, the family has taken on a much healthier lifestyle and I needed to dehydrate more fruits. So after researching a little I bought this Excalibur and so far it has been running since the day I received it. The motor noise that some complain about, really is not all that bad.
Received my dehydrator two days ago and after reading the dehydration guide, set sail on what I thought would be a successful endeavor. Not as I expected. The unit ran fine for three hours under constant supervision then set the timer and went to bed. Woke up this morning excited to inspect the final product and much to my dismay, found my items only partially dried and the fan will now not turn on. The element starts to heat up then after about ten seconds, shuts off.
My husband told me to glue it, I do not think it works, because when you add heat to it, problem will be worse.
There are other reviews with minute detail and comparisons so I'll be brief. I'm using this to prep for a 6 month thru hike, so it's almost constantly running. I like the timer and heat variable. It is quieter than my microwave. The only time it's loud is if I dont get the door on all the way. Then it makes a rattle. Easily fixed. You won't regret owning this.
Both these &#34;problems&#34; have relatively easy fixes: You can leave herbs on the stem until they are dried so they don't get blown all over the inside of the unit; if one tray has food that is a bit tall, just leave out the tray above it.This is not a small counter-top unit. You need to have some place in your home where the size, noise, and heat output won't bother people while it does its job for several hours.
Answer: Yes. Replaced the fan and the timer.
