Refrigerator and freezer are warm (Kenmore model...

Question

Today I noticed my refrigerator temp was rising. I cleaned out the bottom coild (some dog hair) and thought that might help. It didn't. I calld Sears and the soonest they can get anyone out here is in like a week. Right now the Frezer temp is about 15 and the fridge is about 65-70. Is there any thing that I can try to do to at least help meuntil the repair guy gets here>>
