I have no idea what brand refrigerator my brother is bringing me when he arrives for Thanksgiving. It was given to him by a friend that purchased a new one. He stated it get's hot on top because it's trying to make ice and not hooked up to water. Since this is going into the utility room as a second fridge, Im not interested in the ice maker, is a ice maker plug and play so to speak, do they just pull out, or is there wiring involved, since we dont know age or brand. What do you think? Thanks alr2903
