My one year old fridge did a great job keeping bottles cold. So I have recently expanded the dorm size fridge to make space for kegs. I took the door off and added a section the width of the fridge (~19") and 21" long. Not quite finished but sealed enough to test. Anyway the temperature gets down to only 53 F. I have insulation. I put a fan inside to move air. I guess my next step is to cut the new space inside in half. This will be 10" by 19". Anyone have other ideas?
