The panel between the freezer and refrigerator

You need to clean the coils under the front of the refrig of dust , lint , pet hair , etc . Pull the refrig out and remove the back panel covering the compressor . Make sure the fan there , next to the compressor is working . Usually , if this fan is not working , the center strip gets very hot , and the compressor may cut off , from getting too hot . The compressor can burn out , if the fan doesn't work for a while .
