Question: Will these fit the FD-1040?
Document: When you order this product, the NESCO AMERICAN HARVEST LT-2SG ADD-A-TRAY, you get two (2) expansion trays that will fit Nesco dehydrator models FD-75PR, FD-61, or FD-61 WHC.
Fit my FD-60 perfectly. In fact, I took them directly out the box the afternoon they were delivered, washed them, and put them to use immediately drying mangos. They are not the same color as my dehydrator, but I don't care one bit. The price is right, and the quality exactly what I expected from a Nesco product.
I bought these to use with my FD-75PR and the product I received will not fit with my dehydrator. These replacement trays are not the same exact size despite they claim on the side of the box that they came in. They nest just fine on top of the older trays but the dehydrator top will not sit flush on these trays. The problem lies with the center air passage which is about a 1/2" taller than my original trays.
These trays are made for the FD-75 Nesco dehydrator and are the same stone gray color. However, the LT-2W trays (made for the FD-50 and FD-60) are less expensive and will fit the FD-75 also. Additional trays can substantially add to the price of the dehydrator but are necessary for efficient quantity drying. I have eight trays for my dehydrator and consider that the minimum number to best have.
With the chicken jerky treats we make with the FD-61, he no long itches or butt-scoots. And, the treats are so easy to make with cheap frozen chicken breasts from Wal Mart and this dehydrator. I know I kind of got off subject here but you will not regret getting these extra trays as they fit and work perfectly with the FD-61 as well as some other models of Nesco dehydrators. You will find you need them and they are worth buying, trust me.
I have a Nesco FD-75PR, and these do fit that dehydrator. The color matches the top/lid/blower/heat unit. It does NOT match the original trays, which match the bottom piece.This does not really bother me, though, as I will simply use this for organizational purposes (jerky flavors, etc). I don't need my dehydrator to match.I may actually try trays for another model in hopes I get yet another color lol.
(The FD-61 and FD-61 WHC models can be expanded to 12 trays.)
This fits my FD-75A perfectly! Ive made apple chips and jerky with no problems. Easy to clean and not too expensive.
Great addition to the Nesco Snackmaster Pro Food Dehydrator FD-75A. Fits and works great. Allows for more food items to be added.
Bought these for my FD-75A dehydrator to have more room to dry foods.Shipping was fast, took only three days to get here.Will have extra room for my jerky and other treats
Answer: Yes it worked with my dehydrator very well.
