This is a very easy repair as the sensor had 2 screws and slid out of the back of the inside of the oven just enough to hook up the new one. I never had to back the oven out of the wall. It is a 5 minute repair. Ok I did use my son's head lamp from scouts for better light as you have to kill the power to the oven, so no oven light. And you can't hold a flashlight and do this alone.
However, I ordered the part before I took the old part out. Don't do that. There are 2 froms of Temp sensors that you can order one male and one female. I did not know that and just ordered what looked to be the right part. It turned out that I needed the female sensor. When I called the folks at part select they were terrific! They sent out the new part the next day and a UPS form via email to send the other part back.
I don't know what a service call would have been but this was very easy. I will go here first for appliance parts. Women can fix stuff too!
