Ice forming on bottom of freezer floor. Has to be broken up and removed daily. Seems to happen every night.

Most times when that happens it is because the condensate drain is blocked from draining into a pan below the refrigerator where warm air blows across the water and the water is returned to air inside your home. The things need to do is unplug the refrigerator and remove contents of the freezer and then the back panel inside freezer. At the very bottom of the evaporator is a pan that collects the condensate during defrost. It has a drain hole in center. Sometimes the refrigerator is leaning a little and after defrost the ice remains on one side of pan and slowly creeps up to cover the hole completely, while other times the drain line slowly gets gunk build up in it causing water to freeze because of the blockage. I will return with a link to Sea Breeze Tips page where there is a collection of other peoples views to approach this. Sea Breeze
