Kenmore 106.52274202 not cooling

Question

No chance of eating too many Thanksgiving leftovers this year. Got up this morning and discovered everything in my freezer melted and everything in the fridge cool at best. Turned the temp controls all the way up and no change. The fan is running as air is coming out inside, albeit not cold air. I took off the front panel and vacuumed the coils which weren't hot or cold. Also looked at the compressor in the back. It was really hot. The fan next to the compressor was running. Sears repair person won't be out for another three days. Any ideas what might be wrong?
