YES! That is exactly what is happening to mine! It started out one day to the next; the temperature was 38 and then shot up to 59. The old one was working perfectly before it broke down. This happened before so while I was waiting for the new one to arrive, I used the original old part that was still working sporadically. That one froze my food, so I figured it had to do with it being on the fritz. Then I got the new one which I bought direct from GE, no aftermarket, and exactly the same thing happened. The temperature in the panel says it is 42 and the first 2 shelves don't freeze, but the drawers and the doors are freezing everything. I just tried making the freezer a little warmer (had it at 0 and turned it up to 2). I doubt that will make a difference, but I tired.
Quick update: As I said above, I turned up the freezer from 0 to 2, but it did the complete opposite, it went down to -4 and now the top part says it is at 39! Could this be a software issue?
