Hi, my name isXXXXX am hoping that I will be able to help you with your problem today..
where is the water line froze in the unit? it this a SxS model or a bottom mount french door model?
About the only thing you can do is unload the unit and unplug it overnight the day before the tech comes out to repair it, leave the doors open during that time, it will be defrosted by the time he gets there...
