The control panel on my maytag fridge isn't working

I would need to know the model and serial number of the refrigerator to help you. However, Sears quit selling this part. See: http://www.searspartsdirect.com/partsdirect/part-model/Maytag-Parts/Refrigerator-Parts/Model-MTF2455DRQ/3048/0166000/P0504148/00002
The problem is probably not the panel itself, but the wires supplying power. You will have to use a meter to go through it and find out the problem.
