The compressor is working fine - cold air in freezer but bottom - refrig. area is not cold . There is ice along back wall of freezer compartment. I felt air flow from freezer into refrig. area near back wall in bottom althought not much, Where is the defrost/timer on this one? It was not in the bottom on back. Is it under cover housing inside refrig that holds light bulb? Any help thanks Merle

It's part 4 in this diagram of the fridge controls. This is a slightly diff. model number so make sure it's yours.

Problem could also be the defrost heater or defrost thermostat. Refrigerator Repair Guide: How To Fix a Refrigerator - ACME HOW TO.com
