Problem is the drawer above the freezer has no lights shining that would turn on when the freezer opens

This is a new one for me. The above fridge is a french door type with the TV monitor, Pandora, and such. Problem is the drawer above the freezer has no lights shining that would turn on when the freezer were to be opened and the touch panel on this deli drawer is unresponsive. Everything else is working in the fridge.All other lights and it is cooling. Best buy told the customer that the rear main control board would need to be replaced. What say you? Thank you for any advise.
