I bought a Kenmore microwave oven from a second-hand store. They were about to close and I did not have time to Google it. So I bought it, knowing that I can return it if it does not work.
The model number does not show up online. It is nothing like a Kenmore model number. I called Kenmore and they verified that it is not a valid U.S. model number. They said that it could possibly be a Canadian model number. However, the Canadian division shut down recently and supposedly nobody in that huge company would know the characteristics of a Canadian model number.
The model number is KMCMB809BK09. It says it was manufactured January 2023 in China.
I am pretty sure that it is a fake unit but am curious about this phenomenon and would be grateful for any insights about it. I tried searching online for information about fake microwaves but nothing relevant came up. Is it really a fake? Would you use it? It looks real and works. How common are fake microwaves or other appliances for that matter?
