I have ice buildup on the floor of my refrigerator. Manually defrosted it using a hair drier and ensured the drain hole under the unit was clean. But it started icing up again after a week.
I guess the defrost timer or defrost element is broken. Found them on the parts list but how do I get to them in the refrigerator (through front or back)?
To access the evaporator to change out the defrost heater you would need to remove the lower shelves and pull the evaporator cover off. Most likely the water on the floor is not from the defrost heater being broken or the defrost timer. In most cases the drain is clogged and causes the ice build up. It may be necessary to either snake the drain or if the drain hose can be pulled off to remove the drain hose and clean thoroughly.
