Question: How loud is this oven...because of the convection fan?
Document: But doing so feels like you are going to break it. Feels the same for the manual ON setting. The convection fan? Hah! This oven ought to be classified as an oven and space heater with the thermal loss it radiates. The exterior surfaces get dangerously hot. OH, the power cord! It's so damn short you will need an extension cord to reach. Lousy, cost saving engineering, no consideration for ease of use, no interest in the end user.
I'm tired of buying junk. I thought for sure that I would be pleased with this oven from a trusted name, but I wasn't. I researched this thing for a couple days because I surely didn't want to get something that didn't work as it should.When I received it, the convection fan was so off-balance that the oven 'walked' across the counter and would have gone over the edge had I not stopped it. I spent TWO HOURS taking this puzzle of a device apart to balance the blades.
Also, it is not easy to pull out the baking tray or food (bagel, for example) because the rack has a little lip on it. I'm sure it's so stuff doesn't fall out easily, but it makes it difficult to grab a hot baking tray and pull out to see if your food is brown.Finally, this toaster oven makes a loud "clicking" noise during the toast cycle and while warming up for the oven. It's really annoying.
I like it because it is both convection and regular oven, making it more time efficient if it is needed.
Very good product from well known company.Also that it is not only a toaster oven but a convection oven for a good price.
The engineers equipped this toaster with a mechanical timer that is so loud that my neighbor might notice its sound. Be also warned about the virtually inexistent Cuisinart warranty. After Conair bough Cuisinart, the warranty is now "limited". This means that even a day after you purchased a Cuisinart appliance, you will pay half the price of an appliance to have a manufacturing error repaired.
Larger oven dishes fit in with ease. It heats up evenly and quickly. The convection option is very useful and the manual controls are quality.
Great big rack for toast and nice tray for the oven - we can heat up 2 + slices of pizza - or 8 taco shells - etc at a time - Convection is a +++!
This is the best toaster/oven/convection oven/broiler I have purchased. The toast comes out just right and in a very short period of time. I have used the convection feature and it was great.BonnieNY
This is our second Cusinart Toaster oven. The first one did not have the Convection feature which does make a difference in the cooking times. We are thrilled the the performance and the clean up of this item. I woulld highly recomend this for anyone looking for a reasonably priced Toaster Oven.
Answer: not loud enough to be annoying.  convection is optional.
