When using self cleaning, oven door wouldn't open and screen panel went blank.

I searched similar problems on the web and learned that a whole lot of people have Kitchenaid stove with the same problem. They all stated that the thermostat burns when self cleaning. Since technician wanted $190.00, I decided to change it myself. The part cost me $40.00. To instal the thermostat, I removed the panel at the back of the stove and the thermostat is attached with two wires. After I replaced the thrmostat, the screen panel came on and I was able to open the door. I am posting this to tell people that anyone can do this.
