After viewing a video by Parts Select, I pulled freezer from the wall to gain access to the back where the timer is located. I unplugged the freezer from the wall outlet. I then located the timer and used a screwdriver to turn the plastic screw on timer until it clicked once. I then waited a few minutes to see if heating elements would start working. When I heard water sizzling of the elements, I concluded the timer was bad. I then purchased a new timer from Parts Select and replaced it by removing the 2 screws holding it in place. I unplugged old timer and plugged in the new timer, reinstalling it onto the freezer. My 17 year old freezer is working like new again. Thank you Parts Select for everything.

I had the best luck using pliers to remove the hex top screws. Once the screws were removed I unplugged the old defrost timer and plugged in the new one. Replaced the screws and the freezer worked when plugged in.
