Hello, and thank you for using this service. I'll be helping you with your problem today.So to clean the condenser coils, you need to remove the vent panel below the doors. Then you can get a condenser coil brush at a hardware store like Home Depot or Lowes. Then you can put the brush through the holes and clean the coils by scrubbing back and forth. Once they are all clean, pull the refrigerator forward and vacuum under where all the dust drops.Also---is the refrigerator or the freezer section too warm?
The refrigerator section is to warm. If cleaning the coils does not do the trick, what else may be the problem?
That won't fix the refrigerator---that would only fix a freezer problem.If you open the freezer door do you hear a fan running inside the freezer? Is there frost build up on the back panel inside the freezer that you can see if you open the freezer drawer?
