Ice forming around ice maker

Ice forming around ice maker looking at this model GI7FVCXWY62 not sure why there is Ice forming. This Refrigerator is real problem. You say there is a facial heater for the unit. They say there is only a mold heater, when I talked to Whirlpool. They also said they are not having any issues with the unit. There are problems and I don’t know what is real causing the iceing problem. Does the unit have factory problem thats causing this iceing problem. Please let me know I so confused about the whole thing. I just don’t understand why they ever put the ice maker in the upper left side of the refrigerator. I really think it is a bad design. The plastic that you have to pull down is so brittle and you can break a part so easy. All the cold tempatures for years and years of operation. Please let me know if this model of refrigerator does have a fix for ice problem.

Thank You
