I read the comments from others and learned that our freezer was acting similarly to others. Door open errors, interior light flickering, door control panel not responding correctly when buttons pushed, etc. Finally one night the control panel went mostly dark and the freezer temperature alarm went off. A small puddle formed on the floor indicating thawing was beginning. To buy us some time, we went to the local grocery store and bought a couple sheets of dry ice to keep everything cold. Meanwhile, my wife went shopping for a new freezer while I began researching the Internet and found information on AppliancePartsPros.com suggesting the control panel was the culprit and not the mechanical parts of the freezer. So I told my wife to hold off buying a new freezer for 24 hrs while I ordered a new control panel. I received the new panel the next day and thanks to comments from others, I knew that I had to pry off the old one with a couple of putty knives. It was not easy to pry it off, but within 5 minutes I had it off and then it was just a matter of snapping on the new one. Tada' worked like a charm. The entire freezer is now working like new.
For less than $150 our freezer woes are behind us. The estimate for a new freezer, with delivery charges, and removal of the old one was over $850. So this was quite the savings.
