Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today. lets get started.
Okay so you replaced the control board and you are getting power to it? But the control panel will not light up. It sounds like the control panel itself has failed, if you are definitely getting power at the control board and nothing is lighting up on the control itself it's all that's left, it's actually the touchpad is what they call it, you can order this at the following link, touchpad as long as your sure there's power to the control board itself then this is the problem, I hope this helps, thanks, Bryan
