Question: The model Number on the back of the dehydrator indicates I have chrome shelves. However, I ordered stainless steel shelves. Please help. Also, the instructions say there is a warranty card in package but I could not find one.
Document: Furthermore, given that most appliances these are sealed boxes that one does not dare to open I'm pleased to say that the TSM design is simple and functional. All of the electrics are easily visible through the fan vent at the rear and also inside the unit once the stainless food trays have been removed. Should the element ever burn out it looks like a standard item I could get at my local electrical wholesaler.
The dehydrator arrived within a few days of ordering the product. I tried it the next day dehydrating carrots. I noticed the timer didn't work. I contacted customer service and they immediately sent me the back panel which included the timer. My husband exchanged the panel and I now have a working timer. Other than the timer issue all is great with the product. The stainless steel shelves were the reason I bought it to begin with and I wasn't disappointed. It's well made.
A stainless steel food dehydrator with free shipping-could I ask for more? No! So I bought it. I wanted a dehydrator that was bpa free so I decided on this one. I was thrilled with I found this-exactly what I was looking for.
I bought this model because:- it is all stainless steel  (I didn't want to dehydrate my food on heated plastic);- it is beautiful to look at;- it received multiple positive reviews on this site;- it has large stainless steel shelves with a 1/4 inch grid (not on all TSM models);- it has a timer.I would not buy it again because:- it is very noisy! The unit gives off a loud rattle periodically.
I almost didn't purchase this based on other reviews of the 'noise' and being so loud you could hear it rooms away. I think those people got a defective model. This one was purchased USED and it is SILENT - I mean really quiet - I can barely hear it 10 feet away, whisper quiet! I looked at the excalibur model because friends were thrilled with it - but I was very disappointed with the plastic trays and the plastic coating INSIDE the dehydrator.
Though there is a guide on the machine showing which temperature to use for what you are trying to dehydrate, it's not very accurate and I had success my first time using it because I had a thermometer showing the interior temperature. I live in France and was able to find one online here, so I'm sure there are plenty of options in the States.I recommend getting a good Dehydrating book--I really like the Dehydrator Bible.I also recommend getting the sheets so that you can make fruit leather.
It's my first one, and I'm very happy with it and expect to be using it for many years. Love the fact that it's stainless steel and not plastic. This would be a 5-star review if:(1) the controls were located on the *front* of the machine where they could be easily accessed and seen;(2) the side edges of the front cover were thicker or rounded off (thin metal poses a cutting risk)
Seems like TSM has been taking note of customer reviews!I have never written a review and buy from Amazon like it was my neighborhood walmart. So I must say I am pretty impressed with this unit. Unlike the one shown in the pictures there is an updated model of this unit (#30104 D-5) which has addressed most of all the issues that people talk about in the reviews.
This dehydrator is made with great quality. The stainless steal is greatly appreciated as is the spacious interior and moveable shelves. There is a lot of flexibility within what one can do with this machine. The only drawback would be its size. It is quite large. I put it in my basement on top of my dryer, where it quietly does its thing.
When researching which dehydrator to purchase the TSM Stainless Steel dehydrator stood out for a number of reasons:- Front loading square design. Apparently there's a tendency for food to fall into the middle of the cylindrical style dehydrators.- Durable stainless steel construction. The Excalibur which everyone raves about is in the same price range and in made out of plastic.
Answer: I called their customer service and asked about the particular product I ordered.  In my case, they don't even make the unit with chrome shelves in the size that I bought.
