If you look at the bottom of the back panel does the ice cover the vent holes on the bottom?
You have a frozen drain. All that ice has to be removed. The best way is to unplug it and let it thaw with the door open. Place towels around it to catch the extra water. The other will be to use a hair dryer to melt the ice and then remove the rear panel and clear the drain. Either way you will have to remove the panel to make sure there is no debris blocking the drain. If you need for tonight go to the super market and get 3 pounds of dry ice and place it on the top shelf. Make sure that the unit is unplugged when working on it and that the hair dryer is GFCI protected.
