Hi @tonyk2829
Is the compressor motor running, you never said?
If not here's the [document|29347|service manual] for the refrigerator that may help.
Go to p.99 to view the ''When Compressor does not run (Inverter COMP.)'' troubleshooting flowchart.
If the compressor is running, I realize that said that there are no error messages but try running the ''Self-diagnostic function during normal operation'' test for your model series as shown on p.70 and check if any fault codes are being displayed.
Worst case scenario is if there are no fault codes and the compressor is running then it is either a lack of refrigerant in the sealed system due to a leak or a faulty compressor.
