Can anyone recommend someone excellent and reasonable to check out a large Maytag refrigerator that is only 3 years old? Freezer in the bottom. Freezer is working fine, but vents in the back of the freezer keep icing over, preventing cold air flow up into the fridge. Chattooga County area. Fridge cost well over $1000, bought new, what on earth has happened? You're welcome to post here or send me private message. Thanks.
