I have had it with my Whirlpool self-cleaning convection oven.
I bought it two years ago for the sum of $1,500 plus tax - Not cheap. And yet, it has been problem-plagued ever since.
The trouble began when I started baking bread using the convection feature. The control panel would freeze up and not respond at the end of baking. It had a "touch-sensitive" glass panel, and no matter what I did, it would not turn off.
Fortunately, I purchased a five-year warranty with the appliance.
