Horribly mundane problems

The food in the fridge isn't quite cool enough.  It's still running, and the freezer is staying frozen, so the compressor must still be working.

So, I've spent some time just looking at the interior of the fridge.  I think the problem must be the thick layer of frost covering the vents at the back of the freezer.  It's the easy answer.  Also, and easy solution:  empty the freezer into the fridge, turn it off, and leave the freezer door open while I go to karate.  Once it defrosts, clean it up, load it back up. and see how it is tomorrow.

I hope that is all that is wrong.  I really don't want to shell out for a new fridge right now.
