The freezer seems to be holding up. After checking it out last night, it seemed to be cold, so I stuck a few packs of buns in there to see if they would freeze and this morning, they were solid.
I risked it and went and picked up our food and loaded it all back in this afternoon. So far, everything is still frozen. I'm keeping my fingers crossed that it just needed to be defrosted and now it's all better.
Happy freezer= happy Mommy.
