Some buttons on my kitchenaid elect oven don't work

[needhelpwithoven]

Hello, My Kitchen Aid electric stove/oven has a control panel with some buttons not working. The broil button works but not the start button or the maxibroil button. not sure about the other buttons. The stove works fine. I turned off the fuse to the oven for a few minutes and turned it back on - the oven reset and asked me to enter the time, the numbers enter but i can’t press the start to set it - meaning it didn’t fix the problem. It is a white control panel. do i need to replace the whole panel (lots of $$$) or is there a simpler cheaper fix? Any advice would be aprreciated. Thanks
