Ice Maker/Water Dispenser won't light up or work

I have a Maytag Wide by Side and the ice/water dispenser is not working anymore. It does make ice but the lights on the front of the fridge do not light up anymore and I can no longer even turn on the "nightlight" that is under the water dispenser on the door. Any suggestions? Is this a mother board issue? Any help would be greatly appreciated.

Thanks.

PS: I just replaced the Adaptive Defrost Controller for this fridge per the advice of this forum. Thanks for making that an easy job. :-)
