Hi,Welcome to Just Answer, My name isXXXXX will be helping you with your appliance issue today.
Good morning Staci, can you get me the full model number? This should be inside the refrigerator either on one of the side walls or on the ceiling, thanks, Bryan
Okay great, what's going on is your main control board has failed, this is extremely common problem on these refrigerators and GE has had to redesign these boards four times in the last three years, this is the latest board and this is what you need to replace,this is located on the back of the refrigerator if you pull away from the wall you will see a panel 8 x 10" the board is right behind that panel, you can replace this yourself and it comes with instructions but there's no real special knowledge required to do this, the plugs only fit one way so it's pretty easy to replace, you can order this at this blue link.
