Your food is still 'safe' by my standards, Norm. I've had similar things happen, even had stuff that I completely thawed and re-froze without any problems.
I did, however, have a refrigerator that the self-defrost unit went 'wacko' on, long ago. It was, I think, one of the original 'frost free' freezer units sold. To keep the freezer frost free there was a heater unit that kicked on once in a while. In my case it didn't kick off. EVERYTHING in the freezer was thawed and made a huge mess when I discovered it when I got home from work one day. I have no idea how long it had been like that or how warm it actually got.
But that was a time when everything got trashed.
But if it's just not frozen solid but still cold, it's OK. I'd put a container of water in there and see if it freezes and stays frozen. It might be just that the door was ajar and you didn't notice.
