Fridge side warm, freezer side coils frozen over

First off, I am a woman, who did her research, and found that my problem could be fixed by one of two things. Since I heard the refrigerator making a strange noise in the top of the fridge side, I concluded that it was the Adaptive Defrost Timer which had gone bad. I watched the video on how to replace the part, and decided to go ahead and order it (it had already been replaced approx. 4 yrs ago while under warranty). The package came within 2 days - WOW! So, I unplugged, took out the interior roof of the fridge, unhooked the part, plugged in the new part and screwed it all back together. A really easy, inexpensive fix, and it now is cold in the fridge side. Thanks so much for posting the installation video - took all the guesswork out of it. Again, I am a woman, and I did the repair in about 30 minutes!
