Jenn Air range touchpad

The touchpaddoes not work all the time but the clock works. When I press bake the clean and Set comes on and there is a lot on beeping. I can’t get either oven to come on, nor can I get the timers to work. After push the numbers and bake then cancel for about 5 minutes the oven may come on. I can set it to a temp but can’t change the temp. For example I set it to preheat to 350but want to change it to 375. It won’t change unless I hit cancel and try the whole process again. The oven appears to not be baking correctly when it does work. I’m not sure what part to order to get my ovens to work
