I agree with Tom. I had a friend who had the same thing happen. They had cats. I took off the bottom guard in the front and it was completely blocked with hair. With my fridge every 4 months I take the front guard off. Pull it out form the wall. Remove the cardboard covers. And blow air from my compressor from the back and you would believe the stuff that come out. I don't know why they change the air direction. They use to have the fans set so the air would blow from the back out the front. Now they are set up to suck the air from the front, Sucking everything into the coils.
