I went on line and searched what would allow the freezer compartment work but not the refrigerator section. The search gave me several possibilities, so I eliminated each item until I found the evaporator fan was not working. I ordered the part from Appliance Parts Pro because they advertised how fast they shipped their parts. The part left their warehouse on one day and I received it the next. They even had videos how to analysis as well as replace the part. Everything is back to normal. Thanks.
