Both my fridge and freezer were running way too warm. I removed the back panel from the freezer and the coils were frozen over. After reading the fixes others performed. I ordered the temperature sensor and defrost heater & bracket assembly. They came SUPER quickly. I watched the videos for both fixes and got to work. Replacing both parts took about 30 minutes (perhaps less). It took about 24 hours for my freezer and fridge to get to 0 and 37 degrees (the recommended temps). This was such an easy fix that almost anyone can do. My husband was shocked I figured the issue out and fixed this on my own. Our fridge is 11 years old, so he was sure we were going to have to replace it. Saved us a ton of $$$!
