Bottom of freezer icing with thick sheet of ice

You have a froen drain thats why it is allways getting ice on the floor. you need to remove as much as you can then remove the back of the freezer so you can clear the drain pan and clear the drain. its not hard to do just you will have a lot of water on the bottom and your floor maybe. once you remove the ice from the pan have some very hot water and pour it in the pan utill the drain is free and the water go's down into the drip pan. shut the unit off untill tour done and be carefull around the coils. once its clear put the back on and plug the fridge back in. you will now have no more ice build up. make sure there is no food back there that can block the drain either. its a god time to clean the freezer out

We used a hair dryer to melt the ice blockage in drain tube. checked tube to make sure no obstructions, but icing problem continued to happen every few weeks.
