Leak from icemaker shorts electricity in house. Ice maker leaks on 5 yr old side by side fridge

Question

Ice maker leaks on 5 yr old side by side fridge freezer but I dont know why.Ice seems to be made in normal way. Water dispenses OK from door. But the gulley in the bottom of ice bin freezes solid so the auger wont turn and hence trips out the electicity in the house. Water also leaks down back wall of freezer and freezes in little rivers. Invades the fan and causes it to stop working.Water tube is NOT blocked and in any case was replaced with one with an air slot to prevent freezing in the tube.I need to stop the block of ice from forming in the bin, stopping the auger motor and I need to stop the leak down the back of the freezer. I cant live without electricity in the house!
