Hi sometimes thing break, and they will need a service.
In this instance you will need to have a service tech Engineer for appliance repair to come out and do this for you.
The problem is going to be a circuit board, the main processor board that controls everything has failed.
If you could get to the back of the Fridge, I could talk you through the whole repair which is actually quite simple once you get it out from the wall, also I know the best place to get a new board for the best price and a quality circuit board.
There is no soldering needed. It simply plugs in, there are a few plugs but if you take a pic of the locations of the plugs you will have no trouble doing this one;-)
I will help anyway I can all the way through this of you feel up this fix?
Please let me know?
In any case, I will stick with you until this is complete.
