Hello, and thank you for using this service. I'll be helping you with your problem today. First, there is only one main board and it's part number(###) ###-#### It does sound like the unit will need a new board if the unit completely stopped cooling and you have no display board. The location of the control board will be up above the refrigerator in a plastic box cover and it's all plug and play so it should be easy to replace. We are on the honor system here. Please remember to rate my service before you leave today. If you need anything else, just let me know. You can continue asking follow-up questions at no additional charge after rating my service if you still need assistance.
