G.E. Refridgerator Digital read out isn't working

[gtkeith]

G.E came to my house to replace the main board in my refridgerator and since they left my ice and water works but the digital read outs for my temperature controlls when out. When I called and complained about it they told me they had nothing to do with that. They were suppose to send the repair man back but it has been over a year now so I guess they aren’t coming back. Any help would be greatly appreciated because I guess I am going to have to fix it my self. Thanks
