Query: Used 4 times before it completely stopped working!

This toaster oven worked okay the first 3 times I used it and then it completely stopped working - nothing! I only used it once to toast bread and it worked okay, although didn't brown evenly. I used it 2 times to warm-up/brown pre-cooked chicken patties. The chicken worked great, but not today. Now I have to lug it to the service place. This was the first item I've purchased by Delonghi - will not buy a Delonghi brand again.
