Ge Fridge Stopped Working, Hrs Light Blinking!!

My Frdige Stopped Working And The Hrs Light Is Flickering, Nothing Works. I Read A Thread Here From 2009 From People With The Same Issue, Is The Problem The Switchboard Or Mother Board In The Back? Can Someone Please Tell Me What Part Number I Need For My Fridge? Also Are These Parts Available At A Store Like Home Depot? I Would Buy It From This Site But I Need It Today Or My Food Will Go All Bad!!!
Thank You!!
