I purchased a side by side Maytag refrigerator about 5 years ago. In the past 6 months the freezer works fine but other side is warm. I tried to unplug it, vacuum dust in back fan at bottom. A bunch of water leaked out on the floor. I plugged it in and it ran fine for about 2 months. Now the same thing is happening. I could use a self-help manual to trouble shoot this problem. Thanks
