My brother-in-law took a look at the back and wrote down what part I needed to order. I went online and ordered the part from AppliancePartsPros.com. When it came my son and I saw how different it looked (front and back) and decided that we had ordered the wrong part. The replacement part did not have a transformer nor an overlay. I emailed APP.com and told them I had ordered the wrong part. They told me that I needed to send them the Model number and serial number of my stove before they would authorize a return. After I sent them that information they said that I did have the correct part after all. The original part had been discontinued and this was the replacement part. I counted the points (15) on the plug-in and they matched up. I plugged it in and Voila! the oven worked!! Unfortunately, I had no idea what each button did - I needed to order the overlay. I ordered the overlay applied it to the replacement part and replaced the screws, the back of the stove and the other screws and my oven and stove work AND I know how to set the temp/timer/clock, etc. I did the Snoopy Happy Dance because my oven will be functional for Thanksgiving!
