Hello, I have a GE side-by-side refrigerator that is around seven years old. Both the frigerator and freezer are too warm. I removed all of the food, let all of the frost melt and cleaned everything. Refrigerator was unplugged and open for 5+ hours. I cleaned all of the dust and lint from the condenser coils and from under the unit. I then put everything back together, plugged it in and set the controls each to 6. After an hour, both sides were proper temperatures. I replaced all of the food. Everything worked great for 2 or 3 days and then both sides started getting less and less cold. Now the freezer is above 35 degrees and the fridge side is too warm as well. Any ideas what would allow the unit to work properly for a couple of days and then stop cooling again? Thanks.
