We have a GE PDS21SBMABS refrigerator with bottom pull out freezer. Past few days I noticed refrigerator was not as cool and not cooling at all now. The freezer seems to work fine. Any ideas?

I've had this happen before. All the cold is made in the freezer. It is pushed into the refrigerator by a small fan. Sounds like the fan is dead.
I was able to go to the web, order a replacement fan and replace the broken fan.

Thanks Glenn - I think you may be on to it. There is no air coming out of the vent above the temp adjustment, and the wife mentioned some noise that could have been the fan on its last leg. I'll look for some diagrams, but do you remember how you accessed the fan.
